摘要
无线传感器网络中一个好的路由协议能够大大延长网络的生存时间,提高能量的利用效率。分簇路由协议是一种比较适合传感器网络的协议,但是一直没有一种比较成熟的分簇算法和簇头确定算法。为此,提出了采用部分结点进行表决,根据表决结果利用D-S证据理论最终确定簇头的方法。该方法既提高了计算效率又节省了结点的能量。
A good routing protocol can greatly extend the lifetime of WSN and improve energy utilization efficiency. Cluster-based routing protocol is comparatively suitable to WSN, but there is no a relatively mature clustering algorithm and cluster head node determination algorithm by now. Therefore an algorithm is presented, which votes by using a part of nodes, and then decides the head node by D-S theory according to the voting result. This algorithm not only improves computing efficiency, but also saves node energy.
