| 摘 要： | 在深入分析分布式簇头选择路由协议LEACH和集中式簇头选择路由协议LEACH—C的基础上，提出了一种改进的基于分簇的路由协议ILEACH。通过对簇头节点的产生区域进行限定，保证了簇头数目的最优化及簇头的合理分布，以节点剩余能量为主要依据来选择簇头节点。经过NS2仿真平台的测试，改进后的路由协议ILEACH使得整个网络在较低的能耗水平下获得了较长的生命周期，具有较好的能量优化特性。

| Abstract: | Based on the extensive analysis of typical routing protocols,such as LEACH and LEACH-C,an improved clustering-based routing protocol named ILEACH was proposed.The optimal number and the reasoned distribution were ensured by limiting the formative zone of cluster-head and the cluster-head was selected according to the residual energy.Simulation on NS2 platform demonstrated that the improved routing protocol enabled the whole network had long lifetime on the low energy consumption level and had comparatively ... |
