A Mobility-Resistant Efficient Clustering Approach for ad hoc and sensor networks

Abstract

This paper presents a Mobility-Resistant, Efficient Clustering Approach (MRECA) for ad hoc and sensor networks. MRECA can provide robustness against moderate node mobility and at the same time render energy-eficiency. The identified clusterheads cover the whole network and each node in the network can determine its cluster and only one cluster. The algorithm terminates in deterministic time without iterations, and each node transmits only one message during the algorithm. We prove analytically the correctness and complexity of the algorithm, and simulation results demonstrate that MRECA is energy-efficient, resilient against node mobility, and robust against synchronization errors
