Ad Hoc网络移动模型研究

Research of the Mobility Models in Ad Hoc Networks

无线移动AdHoc网络是一种不依赖任何固定设施的移动无线多跳网络。如何选择最贴近实际、最易于实现的移动模型是研究的基础,也是成功的关键。论文研究了几个典型的用于AdHoc网络中的移动模型。分析各种移动模型的关联和差异,给出了各自适用的范围及选择的依据条件,有利于AdHoc网络协议的研究和评价。

Ad hoc networks consist of mobile nodes interconnected by multihop communication paths.Unlike conventional wireless networks,ad hoc networks have no fixed network infrastructure.The selection of the most realistic and the most easy-to-implement mobility model is very crucial for the validity and feasibility of research.In this paper,we describe several mobility models that represent mobile nodes whose movements are independent of each other and several mobility models that represent mobile nodes whose movements are dependent on each other.We present a number of mobility models in order to offer researchers more informed choices when they are deciding upon a mobility model to use in their performance evaluations.The above work is expected to contribute to selecting mobility models or the design of new protocol and planning of the network.
