移动自组网DSDV协议的移动模型和网络负载评估

Evaluation of Varrying Mobility Models & Network Loads on DSDV Protocol of MANETs

C. P. Agrawal, O. P. Vyas, M. K Tiwari

摘要:

移动自组织网络(MANET)是一组相互通信的移动主机组成的自发网络,不使用已建立的网络基础设施。与具有连接基站的有线骨干的蜂窝或基础设施网络不同,移动自组网既没有固定的路由器也没有固定的位置。它们的性能在很大程度上取决于路由机制和移动性的性质。早期的研究表明,目的地顺序距离矢量(DSDV)路由协议是最有效和最流行的协议之一,就一般参数而言。[1,6]我们使用NS2 Simulator对DSDV协议的网络负载、分组投递率和端到端延迟的性能指标进行了实验评估。本文给出了DSDV协议在四种不同移动模型下的性能,即:随机路点、参考点组移动、具有不同网络负载和速度的高斯马尔可夫和曼哈顿移动模型。实验结果表明,基于RPGM移动模型的DSDV协议在网络负载和速度变化的情况下具有较好的性能。

英文摘要:

A mobile ad-hoc network (MANET) is collection of intercommunicating mobile hosts forming a spontaneous network without using established network infrastructure. Unlike the cellular or infrastructure networks who have a wired backbone connecting the base-station, the MANETs have neither fixed routers nor fixed locations. Their performance largely depend upon the routing mechanism & nature of mobility. Earlier research hints that the Destination Sequenced Distance Vector (DSDV) routing protocol is one of the most efficient and popular protocols, as far as general parameters have been concerned.[1,6] We have experimentally evaluated, the performance metrics for network load, packet delivery fraction and end-to-end delay with DSDV Protocol using NS2 Simulator.This paper presents, the performance of DSDV protocol for four different mobility models namely: Random Waypoint, Reference Point Group Mobility, Gauss Markov & Manhattan Mobility Model having varying network load & speed. The experimental results suggest that DSDV protocol with RPGM mobility model has optimized results for varying network load and speed.
