基于空间位置和场景的Ad Hoc路由协议

在移动Ad Hoc网络中,基于拓扑的路由易发生链路断开,基于地理位置的路由易产生拓扑洞,这都会大大降质路由算法的性能,甚至会出现路由失败的问题.为此文中提出了基于空间位置和场景的Ad Hoc路由协议.该协议算法采用构建空间模型,将场景知识引入路由过程的方法,通过在路由前规避拓扑洞来改善和提高路由性能.仿真结果表明在网络连通度适当的条件下,新的路由协议算法可行和有效的.

Ad Hoc Routing Protocol Based on the spatial Location and Scene

In the mobile Ad Hoc network, the link which governed by the routing protocol based on topology disconnected easily, and topology holes easily happened in the link which governed by the routing protocol based on geographical location. These two type routing protocol significantly degrade the performance of routing algorithm, even lead to routing failure problems. In this paper, the routing protocol based on spatial location and scenes has been presented. Through constructing spatial model which introduce the scenes knowledge in routing process and bypassing the topology holes before routing, the routing performance are improved. The simulation results show that the new routing protocol can effectively improve the performance of routing in the proper conditions of network connectivity.
