摘要
传统ZigBee网络路由协议中没有保护剩余能量低的节点,在路由发现中进行广播RREQ等问题。考虑传播路径上的能量消耗,RREQ的发送方向,节点之间的邻居关系,提出一种基于能量的高效路由算法,算法仿真结果表明,改进后的算法有效地减少RREQ的发送数量,增加节点的存活率,延长网络的生存时间。
Traditional ZigBee network routing protocols do not protect the low residual energy of nodes, broadcasting in the routing discovery RREQ, etc. Considers the energy consumption of the propagation path, the sending direction of RREQ, relationship between neighbor nodes, puts forward a kind of efficient routing algorithm based on energy, the algorithm simulation results show that the improved algorithm effectively can reduce the number of sending RREQ, increase the survival rate of the node, prolong the survival time of the network.
