无线Ad hoc网络的现状研究

无线Ad hoc网络是一种特殊的网络,具有分布式的体系结构.其组网简单灵活,支持随时随地通信.在军事,救灾等领域得到了广泛的应用.但由于它的无线多跳,动态拓扑特性对传统通信协议提出了挑战,它的应用还是受到了很大的局限.本文阐述了无线Ad hoc网络的移动、多跳、自组织特点;平面和分级式体系结构;并对无线Ad hoc的有效路由、MAC协议、网络安全和QoS支持等关键技术的研究现状和缺点进行了分析和介绍.

The Development of Wireless Ad hoc Network

Wireless Ad hoc network has a distributed architecture.This type of networks can be organized voluntarily.It also supports ubiquitous communication,and be applied in military affairs,disaster-saving fields broadly.However,some of its performances such as wireless multi-hop,dynamic topology are challenging conventional protocols.This paper analyzed the mobile,multi-hop,self-organized performances of wireless Ad hoc network and its two types of architectures as well as the core technologies such as efficient routing,MAC,security of network and QoS guarantee.
