A Weighted Leach Algorithm for Energy Efficiency in WSN

This research work is related to energy consumption efficiency in wireless sensor networks. Here, we have considered a weighted or Hybrid LEACH-C algorithm in the selection of Cluster Head (CH) in such a way so that its energy is used uniformly with efficient CH selection among clusters for delayed disintegration of network. LEACH-C algorithm based clustering approach has been replaced by multi-objective CH selection method where we not only considered the residual energy of nodes but the position of CH in cluster structure and distance of CH from BS. The Hybrid LEACH-C protocol has been compared with random LEACH and Max Energy LEACH or existing LEACH-C algorithm for energy equi-distribution, network life, stability and throughput. Wireless sensor network (WSN) is simulated using a MATLAB programming and power consumption algorithms take into consideration all aspects of power consumption in the operation of the node. Simulating different algorithm schemes on the same network system, same initial power sources, and routing protocol, an increase of overall system lifetime is demonstrated. The performance of hybrid LEACH-C routing protocol shows improvements in lifetime but at the cost of network stability criterion.
