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。

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.

Key words: MANET, Mobility model, Link, Performance evaluation
