摘要
对已存的请求路由延迟协议进行改进,引入预测生存时间,用来反映当前网络状况下节点的生存时间;此外,还根据节点预测生存时间把节点分成不同等级,从而采用不同的操作,以保护那些预测生存时间较小的节点,进而延长整个网络的生存时间.仿真结果表明该策略有效地延长节点的生存时间.
To improve the exiting Request Delay Route Protocol, this paper introduces the predicted lifetime of nodes to predict the survival time in the current network situation. Further, the nodes are divided into different levels according to their predicted lifetime, and different operations are taken to protect the nodes with shorter predicted lifetime and thus prolong the survival time of the whole network. Simulation results show that this strategy can effectively prolong the lifetime of nodes.
