An access-based energy efficient clustering 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. We developed an access-based energy efficient clustering protocol (ABEE), whose clustering algorithm is based on the outcome of the multiple access to the public channel. ABEE retains the advantage of access-based scheme such as self-organization, flexibility and stability. Also by considering the energy dissipation during 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 to judge the robustness of the network as well as the number of active nodes. Simulation is used to compare ABEE with the exclusively access-based clustering protocol in terms of rationality of the cluster structure, system lifetime and the coverage area. Our result shows that the ABEE can partition the large scale of nodes more rationally, efficaciously improve the system lifetime and the coverage of the whole network.
