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。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 plat- form demonstrated that the improved routing protocol enabled the whole network had long lifetime on the low energy consumption level and had comparatively good power optimum property.
