Performance Comparison of IAODV and OLSR Protocols under Black Hole Attack
-Mandeep singh ; Gagangeet Aujla
A wireless ad-hoc network is a collection of mobile/semi-mobile nodes with no pre-established infrastructure, forming a temporary network.. MANET is a self organized and self configurable network where the mobile nodes move arbitrarily. The mobile nodes can receive and forward packets as a router. Each of the nodes has a wireless interface and communicates with each other over either radio or infrared. Laptop computers and personal digital assistants that communicate directly with each other are some examples of nodes in an ad-hoc network [4]. Nodes in the adhoc network are often mobile, but can also consist of stationary nodes, such as access points to the Internet. Semi mobile nodes can be used to deploy relay points in areas where relay points might be needed temporarily. Routing is a critical issue in MANET and hence the focus of this thesis along with the performance analysis of routing protocols. We compared two routing protocols i.e. IAODV and OLSR. Our simulation tool will be Network stimulator 2. The performance of these routing protocols is analyzed by three metrics: End to End delay, Packet delivery fraction and throughput. Read More...

-Venkat Reddy ; O. D. Hebbal; S. C. Hiremath
Continuous rise in the conventional fuel prices and shortage of its supply have increased the interest in the field of the alternative sources for petroleum fuels. Biodiesel is one such alternative source which provides advantage of pollution control. In the present work, experimentation is carried out to study the performance, emission and combustion characteristics of Rice-Bran biodiesel and diesel. In this experiment a multi cylinder, four stroke, naturally aspired, direct injection, water cooled, eddy current dynamometer, TATA Indica V2 diesel engine is used at variable speed condition. Crude oil is converted into biodiesel and characterization has been done. The experiment is conducted at variable speed condition. The engine performance parameters studied were brake power, brake specific fuel consumption, brake thermal efficiency. The emission characteristics studied are CO, CO2, UBHC, mean gas temperature, exhaust gas temperature and smoke opacity. The combustion characteristics studied are cylinder pressure, mass fraction burned, net heat release rate, cumulative heat release rate and rate of pressure rise. These results are compared to those of pure diesel. These results are again compared to the corresponding results of the diesel. From the graph it has been observed that, there is a reduction in performance, combustion characteristics and emission characteristics compared to the diesel. This is mainly due to lower calorific value, higher viscosity, lower mean gas temperature and delayed combustion process. The present experimental results show that Rice-Bran biodiesel can be used as an alternative fuel in diesel engine. Read More...

Implementation of Solar Powered BLDC Motor Drive
-Deepa A. B. ; Maheshkant Pawar
Renewable energy sources are being increasingly implemented in many applications due to the growing concern of environmental pollution. The PV (Photovoltaic) system appears to be most promising one because it is environmentally clean in nature and it directly converts solar energy into electrical energy. This paper presents the FPGA (Field programmable gate array) based speed control of PMBLDC (Permanent magnet Brushless DC) motor & this BLDC motor is driven by the solar energy. The solar panel is used to obtain the energy needed to run BLDC motor. The voltage obtained from solar panel is stored in battery due to the non-constant nature of solar energy. The voltage from battery is not sufficient to run BLDC motor & hence boost converter is used to boost the voltage required to run BLDC motor. Commutation is implemented on FPGA. FPGA based speed control scheme reduces the complexity of motor control hardware & in turn boost the demand for mobile applications. Read More...

-Dev Raj ; Prof. Kirti Choudhary
Cloud computing has been envisioned as the next-generation architecture of IT enterprise. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, cloud computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. This unique attribute, however, poses many new security challenges which have not been well understood. In this article, we focus on cloud data storage security, which has always been an important aspect of quality of service. To ensure the correctness of users' data in the cloud, we propose an effective and flexible cryptography based scheme.

A Simplied Bit-Line Technique for Memory Optimization
-Revansiddayya ; Siddarama R. Patil
High fan-in and fan-out in read-write of memory requires more area, power, and causes large propagation delay .The number of transistor counts also increases due to large fan-in and fan-out. A simplified bit line technique for power optimization of memory proposed consumes steady power, requires less number of transistors and hence reduces the propagation delay for any fan-in and fan-out of read-write memory. Adopting simplified bit line technique, we implemented 32-word 16-bits/word, 32-word 16-bits/word and so on, 1-read, 1-write ported register files in a 1.2-V/2.5V. By using this technique 2n word x m-bits/words can be achieved with steady power consumption of 2.4mW for 1.2V/2.5V, this power consumption can be further reduced to half of present level by constraining the parameters such as temperature, speed, frequency of operation etc for processing technology.

A Critical Review on the Concept of Effect on Scavenging and Fuel Injection Timing on Two Stroke Engine
-Ravikant Sahu ; Eklabya Gupta ; Deepak Kumar Dewangan; Prakash Kumar Sen; Shailendra Kumar Bohidar
In present study, A spark ignition and a compression ignition engine with uniflow valve scavenging of the cylinder and a transfer valve in the piston crown have been described. A great disadvantage of two-stroke engines is ports which are made in the cylinder bearing surface. Under the heat which is realised during the combustion, the thermal extension of the range in proximity of the ports and other parts of the cylinder is different and so the distortion of the geometry of the cylinder liner surface force the designer to make the clearance between the piston and the cylinder liner bigger. This paper presents the critical review to study the effect of fuel injection timing and scavenging using diesel on the combustion and emission characteristics of a single cylinder, two stroke, air cooled direct injection diesel engine. It is well known that injection strategies including the injection timing and pressure play the most important role in determining engine performance, especially in scavenging emissions. However, the injection timing and pressure quantitatively affect the performance of the diesel engine. Read More...

-Tanushri Mukherjee ; Prashant Bijawat
Microstrip antennas are suitable for mobile and satellite communication systems. This is particularly due to their main characteristics such as low volume and weight, as well as because they are easy to fabricate and to be installed on plane and curved surfaces. Nevertheless these antennas present some disadvantages like narrow bandwidth, low power operation, and radiation loss. There are some methods such as increasing the height of the substrate, which can be used to extend the efficiency and bandwidth. In this communication design and performance of a novel rectangular with finite ground is proposed to achieve wide band performance and circular polarization. “The proposed structure consists of a rectangular patch and the ground plan†Read More...

Trustworthy Service Enhancement in Mobile Social Network
-Ms. Deepa Bagde ; Prof. Sulabha Patil
Mobile Social Network is network which allows mobile users to discover and interact with existing and potential friends. A Trustworthy Service Evaluation (TSE) system is a system that enables users to share service reviews in Service oriented mobile social networks (S-MSNs). Each service provider should independently maintain a TSE for itself that collects and stores users’ reviews about its services without requiring any third trusted authority. These service reviews can be made available to interested users to make service selection decisions. In this three unique service review attacks are identified, i.e., link ability, rejection, and modification attacks, and then develop security mechanisms for the TSE to deal with these attacks. In this we extend the bTSE(basic TSE) to a Sybil-resisted TSE (SrTSE) which enable the detection of two typical sybil attacks. In SrTSE if a user generates multiple reviews toward a vendor in a predefined time slot with different pseudonyms, the real identity of that user will be revealed. Hence a Trustworthy Service in Mobile Social Network is introduces so that users can access services securely. Read More...

An Efficient Interpolation-Based Chase BCH Decoder
-D. Prabhakar ; B. Rajesh; B. Shirisha
Error correction codes are the codes used to correct the errors occurred during the transmission of the data in the unreliable communication mediums. The idea behind these codes is to add redundancy bits to the data being transmitted so that even if some errors occur due to noise in the channel, the data can be correctly received at the destination end. Bose,Ray Chaudhuri, Hocquenghem (BCH)codes are one of the error correcting codes. The BCH decoder consists of four blocks namely syndrome block, chien search block and error correction block. This paper describes a new method for error detection in syndrome and chien search block of BCH decoder. The proposed syndrome block is used to reduce the number of computation by calculating the even number syndromes from the corresponding odd number syndromes. Read More...

Prediction of Fault in Distribution Transformer using Adaptive Neural-Fuzzy Interference System
-Altamash N. Ansari ; Sanjeev B. Jamge
In this paper, we present a new method for simultaneous diagnosis of fault in distribution transformer. It uses an adaptive neuro-fuzzy inference system (ANFIS), based on Dissolved Gas Analysis (DGA). The ANFIS is first “trained†in accordance with IEC 599, so that it acquires some fault determination ability. The CO2/CO ratios are then considered additional input data, enabling simultaneous diagnosis of the type and location of the fault. Diagnosis techniques based on the Dissolved Gas Analysis (DGA) have been developed to detect incipient faults in distribution transformers. The quantity of the dissolved gas depends fundamentally on the types of faults occurring within distribution transformers. By considering these characteristics, Dissolved Gas Analysis (DGA) methods make it possible to detect the abnormality of the transformers. This can be done by comparing the Dissolved Gas Analysis (DGA) of the transformer under surveillance with the standard one. This idea provides the use of adaptive neural fuzzy technique in order to better predict oil conditions of a transformer. The proposed method can forecast the possible faults which can be occurred in the transformer. This idea can be used for maintenance purpose in the technology where distributed transformer plays a significant role such as when the energy is to be distributed in a large region. Read More...

Investigation of Flow Behaviour of Gases in Coal Matrix Sample by Simulation Model in Comsol Multi-Physics
-Lalit Sirvi
Carbon capture and storage (CCS) projects require an accurate evaluation of the sealing potential of faults and highly fractured zones to minimize the potential for CO2 leakage. A study on the control exerted by fracture and fault networks on fluid flow, and in particular on CO2 leakage, should be based upon a representation of discrete fracture networks (DFN) that is as close as possible to that observed in the field. Due to post-lithogenetic fracturing or weathering, coal matrix can contain complex dual porosity structure, which makes it difficult to identify the fluid flow behavior through it. Although CO2-enhanced coal bed methane (ECBM) recovery has been comprehensively investigated, the impact of coal matrix-fracture interactions on the evolution of coal permeability under in-situ conditions is still unclear. In this studies laminar flow models was developed to explicitly quantify the flow behavior of CO2 gas through dual solid media (coal matrix and fracture). A numerical simulation model was developed to simulate flow profiles and fluid flow in COMSOL Multiphysics. The COMSOL Multiphysics model closely predicts the gas flow through the porous coal matrix sample for the range of confining and gas injection pressures studied in low gas flow rates (laminar flow). COMSOL Multiphysics model uses Darcy’s law and Frick’s law for flow simulations. The graphical relations between velocities, pressure, shear stress etc. with Height and Width displacement was studied in this investigation. Read More...

Optimizing the Performance of I-mod Leach-PD Protocol in Wireless Sensor Networks
-Sheetal Kumar Dixit ; Dr. Narendra Yadav; Dr. Saroj Hiranwal
Wireless Sensor Networks (WSNs) is a networks of thousands of inexpensive miniature devices capable of computation, communication and sensing. WSN is being been attracting increasing interest for supporting a new generation of ubiquitous computing systems with great potential for many applications such as surveillance, environmental monitoring, health care monitoring or home automation. In the near future, wireless sensor network is expected to consists of thousand of inexpensive nodes, each having sensing capability with limited computational and communication power which enables to deploy large scale sensor networks. Large scale WSN is usually implemented as a cluster network. Clustering sensors into groups, so that sensors communicate information only to cluster-heads and then the cluster-heads communicate the aggregated information to the base station, saves energy and thus prolongs network lifetime. LEACH (Low Energy Adaptive Clustering Hierarchy) protocol is one of the clustering routing protocols in wireless sensor networks. The advantage of LEACH is that each node has the equal probability to be a cluster head, which makes the energy dissipation of each node be relatively balanced. In LEACH protocol, time is divided into many rounds, in each round, all the nodes contend to be cluster head according to a predefined criterion. This paper focuses on how to set the time length of each round, how to adjust threshold based on the residual energy, and the measurement of energy required for transmission, based on the distance of cluster head from the base station, to prolong the lifetime of the network and increase throughput, which is denoted as the amount of data packs sent to the sink node. The functions of residual energy and required energy, and the time length of each round are deduced, thereby modifying the threshold value calculation. These functions can be used to enhance the performance of cluster-based wireless sensor networks in terms of lifetime and throughput. Read More...

Measurement of Multiparameters using Anaesthesia Injector Based on Arm Processor
-V. Ramesh Kumar ; V. Santhana Lakshmi; G. Merlin Christy Rani; K. Mottaiyasamy
generally the patient should be anaesthetized while major operations are done. If the operations are performed for longer run, the anaesthesia cannot be given at a stretch. The amount of anaesthesia that is delivered to the patient is very important because the over dosage can threaten the life of the patient. If lower quantity is injected then at the time of surgical procedure patient may get conscious and they will feel the surgical pain. To overcome these problems, an automatic anaesthesia machine was designed using an ARM processor. This anaesthesia machine will be very much helpful in delivering the correct amount of anaesthesia in a particular period of time. In this method, a keypad is used for setting the amount of anaesthesia by the anaesthetist and it is delivered using a syringe pump. As soon as the value is entered, the microprocessor accesses the values and starts delivering the anaesthesia through the syringe pump by initiating the stepper motor. The stepper motor is used to drive the syringe pump. According to the stepper motor rotation the amount of anaesthesia will be administered to the patient and if anything goes wrong the alarm will turn on to indicate that there is some problem with the machine.

A Survey on Different Data Hiding Techniques in Encrypted Images
-Sanju Sharma ; Saranjeet Singh
In this paper, we are going to have survey on different data hiding techniques and our main focus is on†Reversible data hiding in encrypted imagesâ€. In recent year the security of the sensitive data has become of prime and supreme importance and concern. To protect this data or secret information from unauthorized person we use many data hiding techniques like stegnography, cryptography and RDH. In this paper we will discuss on one such data hiding technique called Reversible Data Hiding (RDH). In this instead of embedding data in encrypted images directly, some pixels are estimated before encryption so that additional data can be embedded in the estimating errors. Without the encryption key, one cannot get access to the original image. A RC4 algorithm is applied on the rest pixels of the image and a special encryption scheme is designed to encrypt the estimating errors.Our paper presents a survey on various data hiding techniques and their comparative analysis.

Bridge-Stage Framework for the Smartphone Application Development using HTML5
-Mukesh Vijay ; Prateek Diwan; Manoj Raman
Now a days, the Web has become an integral part of our everyday lives. The rapid growth of the smart phone market has brought the Web from our home desks to anywhere we are, and enabled us to access this vast source of information at any time. The mobile operating systems (OS) used by modern smart phones are too diverse such as Google's Android, Apple's iOS, Microsoft's Windows Phone, and so on. Smartphone application development is done using native platform such as iPhone using Objective-C, Android using Java, Windows Mobile using C# and so on. Therefore, a bridge stage framework which supports 'Write once and deploy everywhere' is required to support the development of Smartphone applications. This paper presents the HTML5-based bridge stage framework which uses Phone Gap and Web kit to support the development of Smartphone applications that are written as Web applications. A big problem with developing applications for mobile devices is platform fragmentation [6]. That means that there are many different mobile platforms that are further divided by the different versions available [5][2]. Users with older hardware are left without support and updates as newer devices are put out on the market [9]. This means that the developer has the choice between limiting the solutions and only aim for a minor part of the spectra or to develop for more platforms to reach as many users as possible. To maximize the amount of possible users, the developer has to create an application for each platform and make sure that they are backwards compatible so that users with older devices can use them.

Encryption and Compression of Audio-Video Data Using Enhanced AES and J-Bit Algorithm
-Manpreet Kaur Grewal ; Ms.Sukhpreet Kaur
AES is considered a good encryption algorithm in terms of providing security to a network in passing information (data) in form of audio, string, and video and in any other form. However it yields a low throughput resulting in slowness and increasing energy dispensation of server or an application. The Enhanced AES algorithm is proposed in this paper which works by using sequence counters and provides improved throughput as compare to conventional AES algorithm. The J-Bit Encoding is being a compression algorithm in lossless category which doesn't decrease the quality but reduce the size of data to some extent. It has been observed that the proposed encryption algorithm integrated to J-Bit Encoding algorithm will provide the effective security measures as well as increased throughput as a parameter and less bandwidth usage as the actual size of data shall not be sent along the network.

Fast Sequential Rule Mining
-Bharat Parmar ; Prof. Gajendra Singh Chandel
In this paper, we have proposed a novel sequential mining method. The method is fast in comparison to existing method. Data mining, that is additionally cited as knowledge discovery in databases, has been recognized because the method of extracting non-trivial, implicit, antecedently unknown, and probably helpful data from knowledge in databases. The information employed in the mining method usually contains massive amounts of knowledge collected by computerized applications. As an example, bar-code readers in retail stores, digital sensors in scientific experiments, and alternative automation tools in engineering typically generate tremendous knowledge into databases in no time. Not to mention the natively computing- centric environments like internet access logs in net applications. These databases therefore work as rich and reliable sources for information generation and verification. Meanwhile, the massive databases give challenges for effective approaches for information discovery. Read More...

High Speed Low Power Veterbi Decoder Design for TCM Decoders
-V. Venkanna ; D. Spoorthy
It is well known that the Viterbi decoder (VD) is the dominant module determining the overall power consumption of TCM decoders. High-speed, low-power design of Viterbi decoders for trellis coded modulation (TCM) systems is presented in this paper. We propose a pre-computation architecture incorporated with -algorithm for VD, which can effectively reduce the power consumption without degrading the decoding speed much. A general solution to derive the optimal pre-computation steps is also given in the paper. Implementation result of a VD for a rate-3/4 convolutional code used in a TCM system shows that compared with the full trellis VD, the precomputation architecture reduces the power consumption by as much as 70% without performance loss, while the degradation in clock speed is negligible.

Comparative Analysis of En 45 Steel & Thermoplastic Polyimide (30% Carbon Fibre Reinforced) Used In Mono Leaf Spring Under Static Loading Condition Using ANSYS
-Chetna Wahane ; Abhisek Jain; Vivek Khare
This paper describes design and FEA analysis of mono leaf or single-leaf spring that consists of simply one plate of spring. The performance analysis of spring is under static loading condition. Due to the absorb and release property it is become a major factor in designing the leaf spring which is showing the replacement of steel springs with composite leaf springs. A current leaf spring is made up of a steel material which is having high weight, high corrosion, more noise and the property of material is changing when the load is acting and gives low natural frequency. Therefore, composite materials become the predominant alternative material for replacing the spring steels. The objective of this paper is to compare the load carrying capacity, strength and weight saving of composite leaf spring with that of EN45 steel leaf spring. The design constraints are stress, deflection and weight saving for comfort riding and enhancing durability of spring. Dimensions of the composite leaf spring are to be taken as same as conventional EN45 steel leaf spring used in TATA SUMO GOLD for rear suspension. A Finite element approach for analysis of mono leaf springs using ANSYS R15 software is carried out. Using CATIA V5R20 for modelling the leaf spring. The results are compared with the properties of EN45 steel and thermoplastic polyimide with 30% carbon fibre composite material. Read More...

A Smart Approach to Number Plate Recognition in Tollgate System using FPGA
-S. Lokesh ; N. Ashok Kumar
This paper reveals about the design and development of smart card for automated toll collection through number plate recognition. Since it is simpler and faster than the traditional token based ticket system, it has all the potential to replace the existing system. Moreover, it saves users valuable time by reducing the queue length in front of the toll counter. It is used to pay the amount automatically and open & close the toll gate automatically. We aim to reduce the time consumed to pay the toll gate amount and also to help the police department to trace the vehicle, incase if it was stolen or used for any illegal activities. As well as we are going to increase the security features in the toll gate because now a day's toll gate are the entrance to the main cities. If the Vehicle passed before paying the money the buzzer will automatically ring & the alert will be given to the police also. If any vehicle carries suspicious gas means the buzzer will ring so improved security than the existing systems. The entire system is developed as hardware based system using SPARTAN3 FPGA kit and associated devices. The software for this system has been developed using VHDL language developed in the Xilinx tool. Read More...

An Analytical Model of Latency and Data Aggregation Tradeoff in Cluster Based Wireless Sensor Networks
-Naresh Kumar ; Arvind Sharma; Gajendra Sajedia
Sensor networks are collection of sensor nodes which co-operatively send sensed data to base station. As sensor nodes are battery driven, an efficient utilization of power is essential in order to use networks for long duration. Therefore it is needed to reduce data traffic inside sensor networks, thereby reducing the amount of data that is needed to send to base station. The main goal of data aggregation algorithms is to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. In wireless sensor network, periodic data sampling leads to enormous collection of raw facts, the transmission of which would rapidly deplete the sensor power. A fundamental challenge in the design of wireless sensor networks (WSNs) is to maximize their lifetimes. Data aggregation has emerged as a basic approach in WSNs in order to reduce the number of transmissions of sensor nodes, and hence minimizing the overall power consumption in the network. Data aggregation is affected by several factors, such as the placement of aggregation points, the aggregation function, and the density of sensors in the network. In this paper, an analytical model of wireless sensor network is developed and performance is analyzed for varying degree of aggregation and latency parameters. The overall performance of our proposed methods is evaluated using MATLAB simulator in terms of aggregation cycles, average packet drops, transmission cost and network lifetime. Finally, simulation results establish the validity and efficiency of the approach. Read More...

A New Intelligent Low Cost Mobile Phone Based Irrigation System using ARM
-K. Divya ; D. M. K. CHAITANYA
The major occupation of rural India is agriculture. Insufficient rains at various stages of growth are one of major causes of losses to farmers. Many farmers use induction motor pumps to irrigate their farms from wells, rivers and streams nearby. However, shortage of electric power in many states has resulted in unplanned load shedding of long durations in rural areas. So there is a need to ensure that water is distributed to field whenever normal conditions exist. So a remote monitoring is required. Internet based monitoring is one of common approaches of remote monitoring. This approach requires additional devices like modems, buffers, etc. with TCP/IP protocols support and Internet connection. The cost of such system varies greatly depending on speed and bandwidth requirements and hence is justified normally for bio-medical and industrial applications where intensive data transfer of parameters and images are required. Due to the drastic reduction in call and messaging rates makes cellular networks best choice for this. Moreover, simple cell phones having just messaging facility are available at throwaway prices due to migration of population towards higher end models. Such simple models can be easily adapted for remote control applications. So, a low cost system is developed for optimum water distribution in the fields by providing proper amount of water at suitable time intervals based on climatic conditions and at the real time.
