摘要: 针对无线传感器网络中节点的能量效率和能耗不均衡问题,提出一个组播路由方法。通过把簇以一跳相邻节点为单位重分为更小的子簇,并根据接收消息的延迟把子簇分为不同的等级。对不同等级中的子簇头使用同步非对称休眠机制,对子簇内部的节点使用同步对称的休眠机制,使节点在不接收信息时尽量处在节能的休眠状态。仿真结果表明,该算法能减少能耗并延长网络生存时间。

Abstract: The issue of the unbalanced energy consumption and energy-efficiency of nodes in the Wireless Sensor Network(WSN) are studied and a new multicast routing is proposed. The method makes nodes in the position of energy-saving dormant state when they don’t accept information. It is realized by re-dividing cluster into smaller ones with the one-hop adjacent nodes for the unit and according to the delay of received messages to divide the sub-cluster into different grades, and for different grades of sub-cluster’s head using asynchronous dormancy mechanism and the synchronous dormancy mechanism in cluster’s internal node. The results of simulation show that the algorithm can reduce energy consumption and prolong the network lifetime.
