摘　　要：移动adhoc网络(Mobileadhocnetworks)是一种由无线移动主机/节点组成的动态自治网络。移动adhoc网络在军事和民用方面都有很大的应用前景。在移动adhoc网络中进行有QoS保证的路由选择有重要的意义。论文讨论了移动adhoc网络中的路由选择、QoS保证,并提出了一种新的带宽保证的路由算法ABGR。ABGR以受限扩散路由方法为基础,采用多种机制避免在全网中进行扩散,同时在路由选择的过程中考虑路径稳定性和节点的电能受限问题。Mobile ad hoc network(Manet)i s a set of wireless mobile hosts /nodes forming dynamic autonomous networks.Mane t technology is very promising in both military and commerce.QoS guaranteed rou ting plays an important role in Manet.In this paper,the authors discuss in de pth routing and QoS guarantee issues in Manet research.Specifically,they addre ss the bandwidth guarantee issue in QoS routing and propose a novel bandwidth-g uaranteed routing algorithm AB-GR based on limited flooding,which deploys mult iple mechanisms to avoid flooding in the whole networks.Meanwhile ABGR conside rs the battery-constrained problem and tries to prevent any node from being ov erused early.
