Modified Leach Protocol for Wireless Sensor Network

Wireless Sensor Networks (WSNs) is an emerging area belonging to the wireless technologies that has recently developed interest among the industry and academic researchers and is expected to hold the market in the recent future. In WSN, transferring the data packets with efficient energy during transmission takes the most crucial role in this area, which on failure will result in problems like Single point failure, packet loss and Hot Spot Problem. It may lead to the reduction of network longevity. Grouping the sensor nodes into Clusters will be a better solution for the problem of efficient transmission of data packet with least energy to increase the network longevity. LEACH is the self-organized, adaptive clustering Protocol, which is the most suited algorithm to achieve the network scalability. This paper proposes a modified version of the LEACH protocol, in which the Cluster formation and the Data routing are totally Energy-based. Thus the proposed system first identifies the Cluster Heads and then forms the clusters based on the distance measure. Also the data transmission happens through the most energy-efficient path. The simulation analysis of the LEACH over the existing system shows the improvement in performance attained through the proposed LEACH protocol.
