摘要
Adhoc网络是由一群随机移动的用户终端组成的无须任何固定网络设备的自组织网络。位置辅助路由是Adhoc网络中有别于基于拓扑路由的一种路由方式。它能利用节点的位置信息来指导路由发现、路由维护和包的转发,从而提高了路由的效率。Adhoc网络包括限制性泛洪路由和分层路由两种类型,本文介绍了Adhoc网络及其优缺点,并分析和定性比较了现有的位置辅助路由协议。
Ad hoc network is a kind of self-organized network composed of a group of end systems which can move randomly. Location-Aided Routing is a routing mechanism different from the topology-based routing in ad hoc networks, and it can use nodes’ location information to guide the route discovery, route maintenance and the packets forwarding.In this paper, ad hoc networks, its merits and defects are introduced. Two catalogues of routing algorithms, namely, the restricted flooding routing and hierarchical routing, existing location-based routing protocols are introduced, analyzed and qualitatively compared.
