| 摘 要： | 针对无线传感器网络(WSN)路由协议LEACH 算法中簇首分配不均以及簇首与Sink节点直接通信的问题,提出一种新的无线传感器网络LEACH路由算法.该算法通过节点能量分簇,并在簇首的数据发送过程中引入了改进的多跳路由算法.仿真结果表明,改进后的算法在网络生存时间和节省能量上比LEACH 算法有了很大提高.

| Abstract: | An ant-colony based routing algorithm of wireless sensor network(WSN) was proposed to solve the problems of uneven listribution of cluster-heads and direct communcation between cluster-heads and sink node.The algorithm selects cluster-heads according to nodel energy,and an improved multi-hop routing algorithm was further introduced during the stage of cluster-heads data sending.The results of simulation show that the algorithm is of better characteristic in cluster load balancing than LEACH and can prolong ... |
