移动Ad hoc网络中的终端(节点)既具有主机又具有路由器的功能,在网络通信中网络节点的优良对网络的通信质量具有至关的影响。但节点的状态是一个随机变化的动态过程,对节点状态的实时判断具有一些难度。论文视节点状态的动态变化过程为一个马尔可夫链,采用χ2统计量检验了其马氏性;利用马尔可夫预测模型,预测Ad hoc网络节点在下一时刻的运行状态,进而判断该节点的舍取。
MANET(mobile Ad hoc networks) is a kind of network whose terminal unit(s node)are all be used as mainframe as well as rout er.So the node state is in order or out of order is important to the communication.howerve,it is rand dynamic,and to estimate the node state is not easy.This paper gave a model of Markov chain to discuss the nodes’dynamic process.And the function χ2 was used to verify the property of Markov chain.The result of instance showed that Markov chain to discuss the node state of Ad hoc network is valid.
