多频无线通信网路由协议

针对多频无线通信网的特点,设计了一种多频无线通信网路由协议（MCWN-RP）.协议采用组播扩散机制优化扩散路径,采用非重传确认机制减少报文种类,采用最短路径树构造算法降低扩散内容,采用自适应定时器调整机制减少网络冲突,从而大大降低了协议开销;同时采用差别拓扑更新方式,提高收敛性能.对MCWN-RP进行了协议开销和收敛时间的性能分析,得出协议性能与拓扑更新包大小和协议包发送间隔的关系.OPNET仿真结果表明,与OSPF、OLSR协议相比,MCWN-RP具有非常小的协议开销和较高的收敛性能,是一种高效的动态路由协议.

Multi-Channel Wireless Communication Network Routing Protocol

Based on the characteristics of the Multi-Channel Wireless Communication Network（MCWN）,a MCWN Routing Protocol（MCWN-RP） is designed.The overhead of the protocol is greatly decreased with the multicast diffusion to optimize the diffusion paths,non-retransmission ACK to reduce the packet types,the shortest path tree construction algorithm to lower the diffusion traffic,and the adaptive timer adjusting to avoid network collision.The difference topology update is used to enhance the convergence performance.With the performance analyses of the MCWN-RP＇s protocol overhead and convergence time,their relationships with the size of topology update packets and the interval of protocol packets are given.The OPNET simulation results show that MCWN-RP is an efficient dynamic routing protocol with much less protocol overhead and shorter convergence time than OSPF and OLSR.
