| 摘 要： | 节点移动模型对容延容断网络(Delay/Disruption Tolerant Networks,DTN)中路由算法性能有着重要影响.本文分析校园环境下学生所携带移动节点的运动特点,采用半马尔科夫过程模拟节点运动并建立相应的DTN节点移动模型,对模型进行仿真和分析,将仿真结果与随机路径点(RandomWay Point,RWP)模型及实际路径信息进行对比,可以看出半马尔科夫过程模型能够更准确地描述实际网络环境.

| Abstract: | Node mobility model has great impact on performance of the routing algorithms in Delay/Disruption Tolerant Networks(DTN).This paper analyzes movement characteristics of mobile nodes carried by students in campus.The Semi-Markov Process is used to imitate node movement.And the mobility model of the corresponding nodes is established.Then the simulations and analysises are made about this model.The simulation results show that,in contrast to RandomWay Point(RWP) model and real traces information,the Semi-Mark... |
