摘　　要：提出了一种基于权重的DSR路由改进算法。该算法利用跳数与能量参数构造一个路由权重函数,选择权值最大的路由作为源节点到目的节点之间的路径,以提高整个网络的生命周期。仿真结果表明,该算法可以有效地节省网络能量,延长网络生命,同时减小了网络的端到端延时,提高了网络的性能。A weight-based routing algorithm is proposed in this paper.A routing weight function is constructed by two key elements （energy and hops） in this algorithm,and then the route with maximum weight is chosen as the route between source node and destination node to prolong the lifetime of the networks.The simulation results show that the algorithm can save more energy efficiently and prolong lifetime of the networks.In the meanwhile,it reduces the end-to-end delay and improves the network performance.
