In recent years, the rapid proliferation of wireless networks, usage of wireless devices and deployment of many mobile computing devices and applications has changed the shape of network security. One field which needs more security is the mobile ad hoc network (MANET). The term “ad hoc” means self-organized nodes that do not have a central entity to govern them. Network security plays a crucial role in this MANET and the traditional way of protecting the networks through firewalls and encryption software is no longer effective and sufficient. Denial of service attacks include deliberately dropping packets instead of forwarding them, as well as actively interfering in the communication of neighbouring nodes. A malicious node could attempt to flood the network with its own unicast data packets, potentially using many different destination addresses. In this paper, we analyze the performance of OLSR routing protocol under two different DDOS attacks namely fake hello link flooding and low rate TCP target attack over MANET. we also evaluate the effect of RED-a defense mechanism, against low rate TCP target attack.

Recommendation agents (RAs) are software agents that elicit the interests or preferences of individual consumers for products, either explicitly or implicitly and make recommendations accordingly. Recommendation Agents have the potential to support and improve the quality of the decisions consumers make when searching for and selecting products online. In this paper, a model of recommendation agents is proposed which query over distributed knowledge bases with heterogeneity for our web-based intelligent query answering systems. Ontologies which are the key technology used to describe the semantics of information exchange are also introduced. These Ontologies provide a shared and common understanding of a domain that can be communicated across people and application systems and thus help knowledge sharing and reuse. This model improves the relevance of the query results.

VMS (Video Management System) is a system which manages access and controls the IP cameras. VMS software running on a Windows or Unix/Linux server, supplies the basis for video monitoring via GUI. In General people have VMS on their desktops so they have to stick in front of desktop but here we are introducing a system which runs on Android based phones and tablets and even on web browsers so people don’t have to stick with their desktops they can walk over the premises (where Wi-Fi is necessary) and see the streaming of any IP camera in their android based phone or tablet so you are under surveillance every time even if the controller of VMS is not on their spot. Even ifthey can stream the particular IP camera on the web browser they just need to run the HTML from the server and give the IP of camera on edit text field in browser.Here in this Paper we have introduced “GStreamer Based VMS”, the design is based on GStreamer which is a multimedia framework. The System we have developed is compatible with Windows & Linux desktop (It’s a desktop based VMS made with Java), Android phones & Tablets and All the browsers which has enabled Java plugin (It’s a Java Applet).

Single Sign–on is a new authentication mechanism for user to use multiple services provided by service provider in distributed computer network. It is a one type of application in that allows users to log in once and access to multiple independent applications without being asked to log in again at every application. It enables a legal user with a single credential to be authenticated by multiple service providers in distributed computer networks. In this paper, however, it is shown that most existing SSO schemes have not been formally proved to satisfy credential privacy and soundness of credential based authentication. To overcome this drawback an efficient verifiable encryption of RSA signatures has been proposed.

Sentence clustering plays an important role in many text processing activities. In comparison with hard clustering methods, in which a pattern belongs to a single cluster, fuzzy clustering algorithms allow patterns to belong to all clusters with differing degrees of membership. This is important in domains such as sentence clustering, since a sentence is likely to be related to more than one theme or topic present within a document or set of documents. For example, consider web mining, where the specific objective might be to discover some novel information from a set of documents initially retrieved in response to some query. By clustering the sentences of those documents intuitively can expect at least one of the clusters to be closely related to the concepts described by the query terms. However, because most sentence similarity measures do not represent sentences in a common metric space, conventional fuzzy clustering approaches based on prototypes or mixtures of Gaussians are generally not applicable to sentence clustering. It is a novel fuzzy clustering algorithm that operates on relational input data; i.e., data in the form of a square matrix of pair wise similarities between data objects. The algorithm uses a graph representation of the data, and operates in an Expectation-Maximization framework in which the graph centrality of an object in the graph is interpreted as likelihood. Results of applying the algorithm to sentence clustering tasks demonstrate that the algorithm is capable of identifying overlapping clusters of semantically related sentences, and that it is therefore of potential use in a variety of text mining tasks. It also includes results of applying the algorithm to benchmark data sets in several other domains.

With improvement in sensor technology 3d face recognition has become an imminent technology due to its non co-operative nature. Many researches in 3d face recognition have been dealing with the problem of pose variation, expression, aging and occlusion. We show that under utmost occlusion due to hair, hands, scarves, hates, glass typical 3d face recognition system exhibit poor performance. This paper presents restoration strategy for effective 3d face recognition. In this paper we propose two algorithms for occlusion detection and face recognition. First the occluded face region is detected by matching blocks with the original face. The non occluded regions are then used to restore the missing information. BMA used to restore occluded face. Then apply PCA for recognition. The experimental results show the higher computational efficiency and robustness to occlusion.

In this research paper the focus will be on the Junction­based Multipath Source Routing. It is a geographic routing protocol, in the sense that it exploits the location of the nodes and also of the street junctions, known via digital street maps. The main idea is that it maintains concurrently two paths from the source to the destination as a series of junctions the packets should pass through, and not as a series of nodes­relays. JMSR injects the routing information inside each packet, according to the source routing paradigm, so that every node on the path is aware of the route the packets should follow. In this paper the ananlysis of this algorithm is done, merits and demerits of the algorithm are derived.

TCP is a transport layer protocol which provides reliable and connection oriented transmission. The main problem of TCP is in wireless networks. In wired network, packet loss is mostly due to network congestion, while in wireless network the packet loss may be due to network congestion or may be due to mobility of nodes. TCP starts its back off procedure when it detects packet loss, if the packet loss is due to node movement then the back off procedure will be unnecessary and it will create delay in the network. There are many TCP variants available. TCP Westwood (TCPW) is a sender-side-only modification to TCP New Reno that is intended to better handle large bandwidth-delay product paths (large pipes), with potential packet loss due to transmission or other errors (leaky pipes), and with dynamic load (dynamic pipes). In this paper a better mechanism for congestion avoidance is suggested for TCP Westwood to increase throughput.

Friction welded joints are formed in the solid state by the heat generated by friction. As the technological advancements take place on daily bases the advancements in automobiles are not out of the race. Any form of boosting for engine power leads to increased temperatures and pressures in the combustion chamber, and much higher exhaust gas temperatures. The exhaust valve, which already has much higher temperatures to deal with than the inlet valve in a naturally aspirated engine, will see its temperature increase still further. So bi-metal valves made of Inconel 718 and SS 304 are under development. Exhaust valves are required to be very precise. They are produced by friction welding. The objective of the following study is to study the effects of the parameters on the on the burn-off of friction welded In conel 718 and SS 304 for production of Bi-metal Poppet Exhaust Valve. The study here discuses the use of Design of Experiments by Taguchi Method. Here Orthogonal Array of L25 is used. Using multiple linear Regression and ANOVA effects on the burn-off of welding by Welding Parameters (Rotational Speed, Friction Pressure and Time) are analyzed using MINITAB 17.

Digital communication systems usually represent an increase in complexity over the equivalent analog system. Digital communication has become the most preferred option because of the increased scale of integration, sophistication and reliability of digital electronics for signal processing. In the proposed system the discrete data are EX-OR'ed with randomizer and Convolutionally encoded to transmit data securely. The data is rearranged in Block Interleaver and it is modulated by QPSK (Quadrature Phase Shift Keying) for increasing the signal strength by adding carrier signal and transmitted over to a AWGN (Additive White Gaussian Noise) channel. In the receiver side the received signal is demodulated using QPSK. The scrambled bits are rearranged by Block De-Interleaver and these bits are decoded by Viterbi Decoder. The extra bits decoded by Viterbi Decoder is removed by de-Randomizer which results in original discrete source data. The viterbi decoder increases the channel capacity by adding redundant bits to original bits, it performs Euclidean Distance approach to calculate the distance between the neighbouring signal points, so it performs complex operations. Efficient and secure data transmissions helps to achieve minimum computation.

Digital designs are partial without transmission lines. It has no usually suffered by issues related with transmission line effects. At lower Frequencies the signals remain within data description and the output data same as input data. But as system speeds increase, the higher frequency impact on the system output means that not only the digital properties, but also the analog effects within the system are not ignorable. These problems are likely to come to the forefront with increasing data rates for both I/O interfaces and memory interfaces. Transmission line effects can have a considerable effect on the data being sent. At low speeds, the frequency response has little influence on the signal, unless the transmission medium is particularly long. However, as speed increases, high-frequency effects take over and even the shortest lines can suffer from problems such as ringing, crosstalk, reflections, and ground bounce, seriously hampering the response of the signal. How you can overcome these issues that described in this manuscript for good design techniques and simple layout guidelines.

In this paper, A company (data owner) lacking in expertise or computational resources can outsource its mining needs to a third party service provider (server) taking the advantage of cloud computing. However, a business can have many suppliers and/or customers and may have a set of transactions associated with each one and also the items in the outsourced database and the patterns of items that can be mined from the database are considered as the private property of the corporation (data owner). To protect the corporate privacy, the data owner transforms its data and ships it to the server. The server sends extracted patterns to the owner in response to the mining queries. The owner recovers the true patterns from the extracted patterns received. Here the problem of outsourcing the association rule mining task within a corporate privacy-preserving framework is studied. Proposed model based on background knowledge of Fast Encryption Algorithm (FEAL) Cryptosystem an encryption/decryption strategy for providing security and hence enabling privacy-preserving of outsourced mining task, and protection against the privacy violation attack.

This study presents the application of the GALDIT method, for the mapping of ground water vulnerability to sea water intrusion in the Morbi- Maliya region of the saurashtra coast line. Chachadi andLlobo-ferreira initially in 2001 had developed the GALDIT method. Later in 2005, they had modified the method which is specific for coastal aquifers. The GALDIT index is based on four intrinsic hydrogeological parameters, one spatial parameter and one boundary parameter. The parameters of GALDIT index are: Ground water Occurrence (aquifer type), aquifer hydraulic conductivity, depth of ground water level above the sea level, distance from the shore, impact of existing status of sea water intrusion in the area, and thickness of the aquifer. Each GALDIT parameter has been evaluated with respect to the other to determine the relative importance of each factor. GALDIT index is calculated after deciding the Weightage, range and rate of each factor. GALDIT index is used for study of the Ground water Vulnerability to sea water intrusion. Results shows that Maliya taluka is more prone to sea water intrusion as compare to Morbi taluka.

During the past decade, one clear trend has been observed in the production of metal components. That is every industry work hard to minimize the time required to launch the new product in the market and reduce the cost of operation to maximize profit. As blanking process is the most widely used separation technique in the world but the analysis of blanking process is not done up to that instinct. And also in present day product should be dimensionally so accurate produced by blanking processes, hence it is necessary to study the factors or parameter which are directly or indirectly affect the dimensional tolerance of the blanking product. Metal blanking is a widely used process in high volume production of sheet metal components but after blanking, burr formation at edges of the product is observed and it is not match with the close dimensional tolerance and hence it is need to do the debarring process which is increasing the cost of production and time require for production. Fine blanking is process which helps us to minimize the burr size and like conventional blanking process there are so many parameter which influence the burr height of the product so our main objective of this is to develop a model to predict optimum value of such parameter which influence the burr height of product in fine blanking process and developed the model. The model investigates the effect of potential parameters influencing the blanking process and their interactions. This helped in choosing the process leading parameters for two identical products manufactured from two different materials blanked with a reasonable quality on the same mold.

Since the beginning of the human civilization mankind is trying to communicate with the others. It’s the communication process i.e. the sharing of feelings, emotions and information has made us the greatest creation of God on this green earth. It all started with hand gestures, then sounds. Communication. in wireless communication we mainly exploit the Electromagnetic Spectrum. Earlier systems were narrowband long range systems but in order to extend the use of available spectrum we are now using UWB (ultra-wide band) short range systems which require low power and these are built using in expensive digital components. A microstrip antenna is a narrowband, wide-beam antenna fabricated by etching the antenna element pattern in metal trace bonded to an insulating dielectric substrate, such as a printed circuit board. Microstrip antenna is used for implementing UWB systems as it shows good broadband characteristics. We propose a Slotted MSA (Microstrip Antenna) for UWB (Ultra-Wide Band) applications. The aforementioned antenna is designed using IE3D SOFTWARE. This design consists of a rectangular patch U-shape antenna, two slots have been used which are at the ground. The technique used for feeding is the aperture feeding technique.FR4 substrate has been used because of its lost cost and good reproductivity. The proposed Antennas were successfully designed, simulated and measured showing broadband features, stable radiation patterns and consistent gain. Measured results and graphs show validity of our suggested design.

ECC has gained a lot of focus over a past ten years in literature simply because of its performance. The reason behind this is that ECC when compared with RSA and some other cryptographic algorithm it provides equal security for a smaller key bit size so with this it has less work in processing part. this project, we present a novel mapping of text message into multiple points on Elliptic Curve by using addition table. Then, we describe a new method for encryption and decryption based on matrices. Further, this project also attempts to utilize the properties of invertible matrices in encryption and decryption process with more flexible and efficient. The proposed method enhances the security of ECC with multi fold encryption.
