An access-based energy-efficient protocol for ad hoc wireless sensor network

The ad hoc wireless sensor network is usually deployed in severe environment with limit power supply, whose topology is dynamic and flexible without any fixed infrastructure. In order to facilitate the management and routing, many algorithms have been proposed to partition mobile sensor nodes into clusters. In this paper we developed an Access-Based Energy Efficient clustering protocol (ABEE), whose clustering algorithm is based on outcome of the multiple access to the public channel. ABEE retains he advantage of access-based scheme such as self-organization, flexibility and stability. Also by considering the energy dissipation the compression and transmission of the collected data, ABEE can provide uniformly distributed and energy efficient infrastructure for the upper lever protocols. We also propose to use coverage area to judge the robustness of the network instead of the survival number of nodes. Simulation is used to compare ABEE with the exclusively access-based clustering protocol in terms of rationality of the cluster, system lifetime and the coverage area. Our result shows that the ABEE can more rationally partition the large scale of nodes, efficaciously improve the system lifetime and the coverage area of the whole network.
