摘要
由于无线传感器网络中每个节点的能量都非常有限,在选择路由协议时需尽可能地延长网络生存时间。从限制能耗最大节点的功耗出发,提出一种新的负载均衡的集中式能耗树(CCT-LB)算法。仿真结果表明,相比分布式的WRT算法,该算法能使网络不同比例节点的存活时间提高10%~500%,同时提高网络节点的负载均衡性,从而有效地延长网络寿命。
For each node in Wireless sensor networks (WSN) has only limited energy, it is important to design a power-efficient routing protocol to extend the network lifetime. A new Centralized Consumed-energy Tree Load Balanced (CCT-LB) algorithm has been proposed, which is based on the idea of minimizing the maximum node cost. Compared with the WRT algorithm, the simulation results have shown that the dead time of different proportions of nodes are postponed by 10% to 500%, the energy consumption is more balanced, and the proposed algorithm can prolong the lifetime of WSN effectively.
