A cluster-based topology control algorithm for wireless sensor networks

Abstract

Wireless sensor networks and limitation of their energy resources are big challenges for the researchers at present. Topology control is one of the mechanisms for improving energy consume of these networks. The protocol which is presented is a Neighbor-based Clustering Topology Control Algorithm which is called NCTC. NCTC uses centralized and distributed algorithms. For this reason, it is regarded as a hybrid approach. In addition, it doesn’t need local information for topology construction. NCTC consumes low energy and also it has low complexity message. Simulation results show that in NCTC algorithm network lifetime is prolonged significantly.
