移动AODV路由协议的设计与性能评估

Mobile AODV Routing Protocol Design and Performance Evaluation

无线Ad Hoc网络,又称移动自组织网络,它无需基础设施支持,部署灵活,具有良好的移动性,因而得到了广泛的应用。实现移动多跳Ad Hoc网络关键在于建立可靠的无线通信信道以及实现其所需的路由协议。基于无线视频传输的应用需求,本文选用了WM-G-MR-09芯片设计并实现了WiFi通信模块,用Win-dows CE操作系统平台和IEEE802.11b/g无线网络接口搭建了移动网络环境,通过调用NDIS的API,增加NDIS功能模块的方式,实现了AODV路由算法。然后,对该模块的多跳路由功能进行初步的验证。在此基础上,实现了视频传输,并进行了视频传输实际性能测试,为进一步的研究和改进奠定了基础。

Wireless Ad Hoc networks,also known as mobile Ad Hoc networks,does not require fixed infrastructure.This widely used network has good mobility and can be flexibly deployed.Wireless communication module and routing protocol are the foundation and key property for mobile multi-hop Ad Hoc Networks.To meet the actual requirements,this paper used WM-G-MR-09 chip,designed and implemented WiFi communication module to set up a mobile network environment based on Windows CE operating system platforms and IEEE 802.11b/g wireless network interface.This approach obtained AODV routing algorithm module by calling the API of NDIS.Then,the function of the module for multi-hop routing preliminary was verified,and the video transmission performance was tested.It lays the foundation for the further research and improvement.
