This paper addresses the problem of mobility in large scale wireless sensor networks (WSNs). Our objective is to propose an improved routing algorithm based on LEACH protocol when the nodes are mobile. We, firstly, redefine the analytical energy model when nodes are mobile. According to this model, we calculate the corresponding nodes' energies and the round time length for both mobile single-hop...
In wireless sensor networks (WSNs), reducing sensor node energy consumption and increasing network lifetime are becoming more and more challenging due to large scale. Hierarchical protocols, especially Low Energy Adaptive Clustering Hierarchy (LEACH), are considered as the best energy-efficient for WSNs. However, LEACH need to be enhanced to support scalability in large WSNs. In this paper, we propose...
