一种改进的短波Ad Hoc最优链路状态路由协议

Improved OLSR protocol for HF Ad Hoc

针对最优链路状态路由(OLSR)协议在短波Ad Hoc网路中开销大的缺陷,结合短波Ad Hoc网络特性,对OLSR的拓扑控制(TC)消息的泛洪机制进行了改进,提出了一种基于Fisheye机制的OLSR协议(F-OLSR协议).最后在构建的OPNET短波网络环境下进行了仿真分析.仿真结果表明,该机制的引入有效地减少了网络中TC消息的数量,降低了路由开销,提高了网络的性能.

Aimed at the drawback of huge cost in the HF Ad Hoc network, the flooding mechanism of topolo- gy control （TC） message of OLSR is improved by integrating the characteristics of HF Ad Hoc network, and the OLSR protocol based on the fisheye mechanism, namely F-OLSR protocol, is proposed in this paper, and finally, the simulation analysis is performed under the environmental of OPNET HF network constructed, Simulation re- sults illustrate that the proposed mechanism can reduce the amount of TC messages effectively in the network, thus reducing the routing cost and improving the network＇ s performance.
