Abstract

 In wireless sensor networks in which the topology change is small, to reduce energy consumption in cluster head selection, a cluster-based topology control algorithms is proposed. The cluster head is made much more powerful, partitioning a cluster into two rings. The outer ring is further divided into smaller sectors. This algorithm has advantages of both high efficiency in controlling cluster head center, and flexibility of multi-hop
nodes. A system based on HCTCA can reduce the average transmission radius of nodes and inter-cluster interferences, and improve the network throughput.

Key words： wireless sensor network; topology control; heterogeneous cluster; inter-cluster interference
