| 摘 要： | 针对传感器网络的特点,提出了一种基于权重负载平衡的选播路由算法.该算法的基本思想是根据路径上传输数据的能量消耗、邻居节点的剩余能量和跳数信息计算权重,并选择最小权重路径.新算法通过利用权重让更多节点分担数据传输以保持网络负载平衡,延长网络生存期和改善选播路由的性能.仿真实验表明,新算法的网络生存期是SARP的2到4倍,具有良好的路由性能.

| Abstract: | A load-balanced anycast routing algorithm based on weight is presented for sensor networks.The algorithm chooses the mini-mum weighted routing path,and the weights are calculated according to the energy consumption of data transfer,remaining energy and the hops of the neighbor nodes on the path.More nodes can transmit data by weight,so that the algorithm can balance the network load and prolong network lifetime.Simulations show that the proposed algorithm prolong network lifetime by 2 to 4 times than SARP,and it is suitable for sensor networks. |
