Smart clustering leach (Sc-leach) protocol for improved network survivability in wireless sensor networks

Abstract

Wireless Sensor Networks (WSN) are becoming increasingly popular by the virtue of its diversified applications. Nevertheless WSN faces various research challenges despite its ease of implementation. One of the major issues of concern is the energy efficiency which is closely related to the lifetime of the network. Low-Energy Adaptive Clustering Hierarchy (LEACH) is proven to be an efficient way to route packets in WSNs. However the performance of the LEACH can be further enhanced by lessening the frequency of cluster reformation. In this paper we propose a novel Smart Clustering LEACH (SC-LEACH) protocol which is an advancement over the traditional LEACH protocol. The results of the proposed algorithm were validated through simulations.
