隐式路由协议的一种转发节点快速选择算法

A forwarder fast selection algorithm for implicit routing protocol

文章针对已有隐式路由协议转发节点选择算法效率不高的缺点,提出了一种转发节点快速选择算法。该算法不仅从整体上考虑一条路径上节点的剩余能量,而且还考虑了节点的可选下一个转发节点的数目。仿真实验结果表明,该算法有效地平衡了网络能量,能够快速地选择转发节点,减小了信息传输中的延时,从而延长了整个网络的生命周期。

Aiming at the inefficiency of current forwarder selection algorithms for implicit routing pro- tocol, this paper proposes a forwarder fast selection algorithm. Both the remainder energy of the node in a path and the number of optional forwarders of the node are taken into account in the algorithm. The result of simulation experiment shows that the algorithm can effectively balance the energy of WSN, fasten the forwarder selection and shorten the time delay of information transmission, which prolongs the lifecycle of WSN.
