| 摘 要： | 利用区域分割的方法建立了一种覆盖区域冗余节点的优化调度机制,实现对完全覆盖区域内冗余节点的休眠调度,并将该机制引入无线传感器网络的分簇结构中,提出一种基于分簇拓扑的节点调度优化算法。算法通过控制簇内冗余节点进行休眠,减少簇首的数据通信量和簇成员中工作的冗余节点个数,降低了网络能耗。仿真结果表明,与未考虑冗余节点休眠调度的分簇算法相比,该算法有效提高了网络能量利用率,延长了网络生命期。

| Abstract: | In this paper,an optimal scheduling mechanism of redundancy nodes in coverage area is built by applying the method of regional division.And the scheduling mechanism of redundancy nodes is achieved to ensure complete coverage of the region.By introducing the scheduling mechanism to clustering topology of wireless sensor networks,an algorithm of nodes optimal scheduling based on clustering topology is proposed.The algorithm controls the redundant nodes' sleeping in order to reduce the data transmission of clu... |
