Ad Hoc网络移动模型及其应用

现今对Ad Hoc网络的研究如火如荼，基于Ad Hoc的系统性能分析和协议行为设计逐渐成为研究的主流。如何选择最贴近实际、最易实现的移动模型是研究的基础，也是成功的关键。本文总结了几种常用于Ad Hoc网络中的移动模型。其中有节点之间独立移动的实体移动模型，也有由一些节点组成一个整体，按照一定的约束一起移动的组移动模型。。本文通过分析各种移动模型的关联和差异，给出了它们各自的适用范围以及选择的依据条件，为今后在协议设计和网络规划等要求下的移动模型的使用和新的移动模型的设计实现打好了基础。

A Survey of Mobility Models for Ad Hoc Networks

Nowadays, there is tremendous research work about Ad Hoc networks, in which many efforts focus on the performance analysis and protocol behavior design. The selection of the most realistic and the most easy-to-implement mobility model is very crucial for the validity and feasibility of research. This paper presents several mobility models commonly used in Ad Hoc networks, representing mobile nodes whose movements are independent of each other and several mobility models that represent mobile nodes whose movements are dependent on each other. Through analyzing their associations and differences, we describe the application environments of each model and the qualification conditions of selecting models. The above work is expected to contribute to selecting mobility models or the design of new mobility models in order for the protocol design and planning of the network.
