Modified Distributed Energy-Efficient Cluster for Heterogeneous Wireless Sensor Networks

Abstract

Abstract. The existing information collection system is a heterogeneous communication system which includes WSN (wireless sensor network) and wired network. In a heterogeneous information collection system, the survival time of nodes is very important for the stability of the network. How to reduce unnecessary energy consumption and make energy consumption more balanced requires special consideration. In this paper, we firstly explore the necessity of using clustering algorithms, and then analysis the existing heterogeneous wireless sensor network clustering algorithms, finally modify the existing DEEC (distributed energy-efficient clustering algorithm). The modifications of DEEC algorithm aims at the unstable performance. Simulation results show that the MDEEC (modified DEEC) has a greater network lifetime than DEEC.
