无线传感器网络分簇拓扑控制算法的研究

Wireless Sensor Network is a densely deployed resource stress network. Topology control is one of the most fundamental problems in wireless sensor networks．Excellent topology construction could improve the efficiency of routing protocol and MAC protocol，provide the basis for data aggregation、time synchronization and object localization，also prolong the lifetime of network．For large-scale deployment of sensor networks， Cluster-Based Topology Control Algorithm mechanism has been presented．Several representative algorithm are analyzed and compared with each other，LEACH algorithm is well researched particularly. Finally, existing problems ,open issues are analyzed and summarized, the further research trends are also pointed out.
