| 摘 要： | GAF算法是现阶段提出的一种以地理位置为依据的路由算法,但没有描述具体的底层通信协议.按照GAF算法的思想,结合AODV,DSDV,DSR三种路由协议作为底层协议,比较其性能优势.仿真时利用了NS2网络仿真软件,选取包传送概率和网络总能耗两个指标对引入GAF算法后的三种新协议与三种传统协议进行性能评估,并通过改变节点密度和单元格数量等参数分析比较了这两个参数对六种协议的性能影响,仿真结果表明GAF算法在节能方面优势明显.

| Abstract: | GAF is a routing algorithm based on the location of nodes in wireless sensor networks,but it doesn't describe the lower communication protocols.Firstly this paper introduces the theory of GAF in order to reflect the performance advantage of GAF,the simulation soft tool NS2 is used and the average packet delivering rate and the energy conservation are chosen to evaluate the performance of the protocols with GAF and the traditional protocols AODV,DSDV,DSR.Then the effects of these parameters on the performanc... |
