无线Ad hoc网络的现状研究

The Development of Wireless Ad hoc Network

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。

Wireless Ad hoe 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.
