摘要: 对无线传感器网络的路由协议进行了分析研究,重点对LEACH协议进行了深入的探讨,发现LEACH协议的随机选择簇头的方案没有做到最优,因为它在选择过程中没有考虑节点剩余能量,且簇头节点在与基站通信时采用单跳通信,针对LEACH存在的不足,进行了改进,提出了EECH协议。通过NS仿真比较表明,改进的协议有效地延长了网络的生存时间,提高了网络的效率。

Abstract: The paper studies the WSN routing protocols and analyzes the performance of LEACH in-depth.It is found that the cluster heads selecting arithmetic in LEACH is not the best,because it dose not take the residual energy of the nodes into account.And when it communicates with the sink,it is in the form of one-hop routing.Then the paper makes the improvement and presents the EECH arithmetic according to the shortage of LEACH.The new present protocol has a better performance on the lifetime of the network than LEACH through the simulation with NS2.
