Adhoc网络及其路由性能研究

Adhoc是一组无线移动主机组成的一个无需基础设施或集中管理设备的临时网络。网络拓扑易变、带宽、能源有限是其主要特点。主要介绍Adhoc网络及其组网关键技术——路由协议，并对现在的具有代表性的协议性能进行了比较分析，有助于从事Adhoc网络的工作者综合各种路由的优点解决Adhoc网络中存在的问题。

Analysis of Ad hoc network and its routing performance

Mobile Ad Hoc Networks (MANETs) are collections of wireless mobile nodes constructed dynamically without the use of any existing network infrastructure or centralized administration. Due to the limited transmission range of wireless network interfaces, multiple hops may be needed for one node to exchange data with another across the network. MANETs are characterized by limited power resource, high mobility and limited bandwidth. Routing in MANETs is a very important technology. In this paper, the authors introduce the Ad hoc network and the kay technology routing protocol, analyze and compare routing in Ad hoc networks in terms of delay, traffic distribution and connection throughput. The results show that in comparison with AODV, DSR and CBRP,the mechanism creates more delay and overhead but provides better performance in connection throughput.
