Abstract

The network routing could be simplified by clustering algorithm in wireless sensor network (WSN). Aimed at the occasion with a large amount of nodes but without whole-network time synchronization mechanism, a self-adaptive clustering algorithm for network topology control is proposed. In this algorithm, the cluster structure can be adjusted automatically according to the nodes distribution and network traffic. By adopting loop-avoidance mechanism, the correctness of routing selection is ensured when adjusting the cluster structure. The simulation results demonstrate that the proposed algorithm can reach the expected effect of self-adjustment.
