A Four-Layers Hierarchical Clustering Topology Architecture with Sleep Mode in a Wireless Sensor Network

Abstract

In this paper, our proposed architecture involve new four-layer clustering topology architecture based on LEACH architecture. We propose four-layer clustering topology architecture: the Random Cluster Head and Maximum Energy Sub-cluster Head with Relay node and Sleep mode (RCHMESHR-S) architecture, the aim is to improve energy efficiency and extend the lifetime of wireless sensor networks. The RCHMESHR-S architecture considers the residual energy of wireless sensor nodes when selecting the sub-cluster head and relay node, in order to increase the energy efficiency of a wireless sensor network. Furthermore, the RCHMESHR-S architecture uses correlations among sensor data within wireless sensor nodes to develop a sleep mode that can effectively reduce energy consumption. Simulation results show that the performances of our proposed RCHMESHR-S architecture is better than that of the LEACH architecture in terms of initial node death and the number of nodes alive.
