【摘要】 移动自组网的节点运动模型描述了节点的运动情况,采用合适的运动模型对于分析各种协议性能具有重要的意义。该文结合移动自组网络中路由协议的相关属性,提出了邻居节点比率、链路生存时间和平均链路保持时间3种评价指标,并通过大量的模拟实验分析和比较了随机行走运动模型、随机停留运动模型、高斯-马尔可夫运动模型和无边界运动模型4种运动模型,这对于考虑不同运动模型下路由协议的设计十分重要。更多还原

【Abstract】 Mobility model is used to describe the movement of node in MANET.Utilizing a proper mobility model is important for performance evaluation.The paper gives three evaluations— neighbor ratio,link life time and average link life time based on correlative properties of routing protocol.Under a lot of simulation,it analyzes and compares the random walk,random waypoint,Gauss-Markov and boundless simulation area mobility models.These results are helpful to protocol designation,especially to the routing protocol in MANET.更多还原
