| 摘 要： | 对现有的LEACH算法进行了简单的介绍,分析了此算法的不足之处并进行了研究和改进.首先,从簇头数目的最优化入手对原有的LEACH算法进行了改进.其次,针对原有LEACH算法会造成簇头节点分布不均这一问题,以节点剩余能量为主要依据来选择簇头节点的改进算法,并采用多跳方式传输数据.仿真结果表明在网络生存时间方面,所提出的多跳能量感知路由算法优于LEACH协议.

| Abstract: | Based on the analyzing of LEACH protocol,this paper mainly studies the shortages,and then puts forward some improvements to LEACH protocol.Firstly,this study improves the formula by optimizing the number of cluster-head node.Secondly,there is a problem of unbalanced distributing of cluster-head nodes which are improved by resetting up the probability parameter,so a new protocol,multi-hop adaptive protocol,which depends on residual energy of every node is promoted to select clusters periodically.The result of this study shows that this new protocol can prolong lifecycle. |
