Abstract:
From hierarchical routing protocols, Low-Energy Adaptive Clustering Hierarchy (LEACH) has been considered as one of the effective algorithms that optimize energy and prolong the lifetime of network. In this paper, we propose a new approach of electing Cluster Head (CH) based on LEACH protocol. The selection of Cluster Head (CH) in LEACH is carried out randomly. In our proposed approach, we consider three fundamental criteria: the remaining energy, the number of neighbours within cluster range and the distance between node and CH. In fact, in our algorithm, we include these factors in calculation of threshold. Simulation results shows that our proposed approach beats LEACH protocol in regards of prolonging the lifetime of network and saving residual energy.
