Comparative Analysis of Topology Control Algorithms to Enhance Network Lifetime

Topology issues have received more and more attentions in Wireless Sensor Networks . WSN applications are normally optimized by the given underlying network topology. Topology control is an effective method to improve the energy efficiency of wireless sensor networks. Due to the severe resource limitations of the sensor nodes (e.g., small battery, limited computation capabilities, inexpensive transceiver etc.), Lifetime extension is one of the most critical research issues in the area of wireless sensor networks. One of the key approaches for prolonging the sensor network operable lifetime is to deploy an effective topology control protocol. In this survey paper, we provide a full view of the studies in the area of topology control in Wireless sensor network. By summarizing previous achievements and analyzing existing issues, we also point out challenges and research directions for future work.
