A New Reliable and Energy Efficient MAC Protocol for Wireless Sensor Networks

In wireless sensor networks (WSN) the important parameter which is used to measure the performance of protocols is the energy efficiency. As the applications of WSN are in remote areas it will almost be impossible to recharge or replace the batteries of sensor nodes. Also the number of sensor nodes in a network may be very large. Therefore the aim of this research paper is focused upon an energy efficiency in medium access control (MAC) protocols for improved lifetime of sensor nodes.This research paper tries to focus on design and development of an energy efficient and reliable MAC protocol based on the TDMA, IEEE 802.15.4 wireless-MAC and physical layer provisions for WSN. MAC protocols for WSN have problems of consuming high energy in communication algorithms and processing techniques. MAC protocol proposed in this paper will achieve good energy efficient performance in terms of reducing unnecessary execution and optimizing transmission algorithm. MATLAB simulation has been used to test the performance of proposed MAC protocol. Simulation results shows the comparison of proposed approach with existing approaches and depict that proposed approach have good performance
