Abstract

Mobility models play an influential role in the simulation studies of mobile ad hoc networks (MANETs). Realism and simplicity are two attractive properties of mobility models, and achieving both together in modeling mobility has been a challenging task. Recently, a framework of moblity models called destination guided mobility (DGM) models for MANETs was proposed. This framework can be used to develop several simple DGM models with increased realism. Connectivity is a fundamental requirement for communication between nodes. In this paper, we investigate the connectivity in two basic DGM models in comparison with the widely used random waypoint (RWP) model. Specifically, first we expand the DGM models development and analysis software tool to include connectivity analysis. Second, we provide the experimental evaluation of connectivity in the two basic DGM models in comparison with RWP model. Finally, through NS2 simulation, we study the performance impact of these mobility models on the Ad-hoc On-demand Distance Vector (AODV) routing protocol - one of the most popular routing protocols for MANET.

基于目标导向移动模型的移动Ad Hoc网络连通性分析

移动性模型在移动自组网(manet)的仿真研究中起着重要的作用。现实性和简洁性是机动性模型的两个吸引人的特性，在机动性建模中同时实现这两个特性一直是一项具有挑战性的任务。近年来，提出了一种面向manet的目的地引导移动模型(DGM)。这个框架可以用来开发几个简单的DGM模型，增加真实感。连接性是节点间通信的基本要求。本文研究了两种基本DGM模型的连通性，并与广泛使用的随机路径点(RWP)模型进行了比较。具体来说，首先我们扩展了DGM模型的开发和分析软件工具，以包括连通性分析。其次，我们对两种基本DGM模型的连通性进行了实验评估，并与RWP模型进行了比较。最后，通过NS2仿真，我们研究了这些移动模型对自组织按需距离矢量(AODV)路由协议的性能影响，AODV路由协议是MANET中最流行的路由协议之一。
