Research On Energy Efficient Hierarchical Clustering-Based Leach Protocol for Wireless Sensor Networks
Abstract
The aim is to reduce the energy consumption of nodes and maximise the lifetime of the sensor network. The original LEACH (Low Energy Adaptive Clustering Hierarchy) protocol selects the head cluster based on random number generation and does not consider the residual energy of the nodes. In this paper, we propose a modified head cluster selection algorithm and cluster formation algorithm. Cluster formation is based on the nearest neighbour distance algorithm, which is an improvement over the k-means algorithm for forming the clustering structure. The simulation results show that the proposed protocol has improved the occurrence of nodes in a non-working state, the percentage of alive nodes, the residual energy, and the throughput of the sensor network.
