基于位置路由算法的基本思想是基于节点的位置信息来选择下一跳,将包向目的节点的方向上进行转发。由于不必维护明确的路由,基于位置的路由协议即使在网络高度动态的情况下也具有很好的扩展性。这是在拓扑经常变化的MANET网络中的一个主要优点。文章对基于包的目的节点的地理位置做出路由决定的算法进行了总结,并对这这些方法进行了定性的比较。
The basic idea of position based routing algorithm is to select the next hop based on the position information of nodes, and forward the packets to the direction of destination. The position based routing protocols are adaptable to the dynamic mobile Ad hoc networks due to not maintain explicit routing, and this is an advantage in the topology changing frequently MANET. This paper reviews the routing algorithms that make routing decisions based on the position information of desation in mobile Ad hoc networks, and compares their performance qualitatively.
