| 摘 要： | 提出一种基于最优簇头数的无线传感器网络安全LEACH路由协议,该协议模拟真实传感器网络情况建立了三维空间模型,通过理论分析和仿真实验方法得到LEACH协议的最优簇头数,使网络能耗达到最优.在能量优化的同时把增强安全性作为设计目标,根据LEACH协议的特点,采用预置共享密钥对的方法,在簇头选举和数据传输阶段采用在数据包尾部捎带加密信息的方法,实现数据加密,在只增加少量能量开销的情况下数据机密性得到了实现.仿真验证了新协议的有效性,在能量优化的同时提高了路由安全性,延长了网络生命期.

| Abstract: | In this paper we put forward a secure LEACH(Low Energy Adaptive Clustering Hierarchy) routing protocol based on optimal number of head nodes for wireless sensor network.This protocol establishes a three-dimensional space model by simulating real sensor network,and achieves the optimal number of head nodes through theory analysis and simulation testing of LEACH.Thus,the optimized energy consumption can be obtained.At the same time,the enhanced security is also regarded as the design goal.According to the cha... |
