在对自组织网络协议进行性能评估时，该协议应在现实条件下进行测试，这些条件包括但不限于合理的传输范围、用于存储消息的有限缓冲区空间、有代表性的数据流量模型以及移动用户的实际移动情况（即移动模型）。本文是对自组织网络模拟中所使用的移动模型的综述。我们描述了几种表示移动节点相互独立移动的移动模型（即实体移动模型）以及几种表示移动节点相互依赖移动的移动模型（即群组移动模型）。本文的目的是介绍一些移动模型，以便研究人员在决定其性能评估中使用何种移动模型时能有更明智的选择。最后，我们给出了模拟结果，这些结果说明了在自组织网络协议模拟中选择移动模型的重要性。具体而言，我们说明了自组织网络协议的性能结果如何因所模拟的移动模型的改变而发生巨大变化。版权所有 (C) 2002 约翰威立父子有限公司
In the performance evaluation of a protocol for an ad hoc network, the protocol should be tested under realistic conditions including, but not limited to, a sensible transmission range, limited buffer space for the storage of messages, representative data traffic models and realistic movements of the mobile users (i.e. a mobility model). This paper is a survey of mobility models that are used in the simulations of ad hoc networks. We describe several mobility models that represent mobile nodes whose movements are independent of each other (i.e. entity mobility models) and several mobility models that represent mobile nodes whose movements are dependent on each other (i.e. group mobility models). The goal of this paper is to present a number of mobility models in order to offer researchers more informed choices when they are deciding on a mobility model to use in their performance evaluations. Lastly, we present simulation results that illustrate the importance of choosing a mobility model in the simulation of an ad hoc network protocol. Specifically, we illustrate how the performance results of an ad hoc network protocol drastically change as a result of changing the mobility model simulated. Copyright (C) 2002 John Wiley Sons, Ltd.
