【摘要】 移动模型决定节点如何移动,它是对节点运动方式的抽象,已被广泛应用于无线网络相关研究中。首先介绍了当前常用的移动模型,并对其进行了分类比较;接着论述了当前研究主要集中在提出新的适合各种移动环境的移动模型、对移动模型的节点移动特征进行分析、对追踪移动模型的追踪策略研究和对移动模型的评估等;然后给出了移动模型目前存在的问题;最后指出了移动模型的研究趋势。更多还原

【Abstract】 Mobility model decides how the nodes move and describe mobility manners of nodes.Hence it has been widelyused in research on wireless network.This paper firstly introduced,classifies,and compares the current familiar mo-bility models.Secondly,it was discussed that current research focus on new mobility models,analysis of nodes mobility features,trace strategy,and evaluation of mobility model.Next,it was covered the existing problems of mobility models.Finally,this paper involved what calls for further study.更多还原
