An Improved LEACH Protocol by Using Two Suitability Functions

Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is the first hierarchical cluster based routing protocol successfully used in the Wireless Sensor Networks (WSN). The low-energy adaptive clustering hierarchy (LEACH) protocol is one of the Famous protocols used in the wireless sensor networks. The LEACH protocol suffers from many Bugs and many researchers proposed different methods to mitigate them. In this paper, we propose two ideas for improving LEACH protocol. Cluster head election with use a likely attributable function, there is in this function a factor. This factor helps to farther nodes not election for cluster head. This significantly decreases the energy consumption and increases the lifetime of associated nodes. In next stage, for election cluster member, using one other suitability function. Simulation is conducted in using MATLAB results are analyzed for energy consumption.
