Energy Efficient Topology Control for QoS of ad hoc wireless network

This paper we discusses the energy efficient topology control issue in ad hoc wireless networks. In order to find an optimal network topology that has maximal network lifetime meet QoS requirements, which is involved with traffic requirements, hop bound and bandwidth, we design an Energy Efficient Topology Control algorithm that integrates a relevant QoS Routing algorithm. In the course of comparing most of algorithms concentrated on how to minimize energy consumption, the combined analytical and numerical results indicate this optimal algorithm can obtain an optimal network lifetime, which is a genuine time value and more significant and reasonable than taking minimizing energy consumption into account purely.
