| 摘 要： | 本文研究m覆盖与连通的无线传感器网络中的节点调度问题,提出了一种两跳簇的概念,并在此基础上提出了一种新的节点调度算法.该算法可在不知道节点位置信息的情况下,将无线传感器网络中的所有节点较为均匀地指派到k(km)个不同的分组{0,1,...,k1}之中,且可同时保证每个分组中的节点具有全局连通性与较高的网络覆盖率.理论分析与实验结果表明,该算法具有比传统随机调度方法更好的节点调度性能,可更加有效地延长无线传感器网络的生命周期.

| Abstract: | By researching on the node scheduling problem of m-covered and connected sensor networks,a new concept of two-hops-cluster is proposed in this paper,and based on it,a new distributed node scheduling algorithm THCNS for allocating all nodes in the sensor network into k (k m) different groups {0,1,...,k 1} is designed,without requiring location information.Our algorithm guarantees that each group to be connected and maintains the coverage ratio with high possibility.Theoretical analysis and simulation results... |
