基于区域划分的无线传感器网络生命周期路由算法OA北大核心CSCDCSTPCD
Lifetime routing algorithm based on regional division in wireless sensor networks
为了解决能量密度路由算法的路由空洞问题,均衡网络中的节点负载,延长网络的生命周期,提出利用节点间的耦合性对监测区域的传感器节点进行划分的方法,采用区域内与区域间两种数据传输方式,并且不同子区域使用不同的路由更新频率.仿真实验表明,新算法在网络运行前期能够成功地避免空洞,均衡网络能量消耗,延长网络的生命周期.
In order to solve the routing holes problem of energy density routing algorithm and to balance the load of nodes in network as well as to extend network lifetimes, this paper proposed a method to divide nodes in surveillanc'e regions according to their coupling relations, and took advantage of regional and interregional data transmissions, with different route updating frequencies in. different sub-regions. Simulation shows that the new algorithm can success…查看全部>>
