针对多UUV编队控制系统水声通信的特点,提出了一种基于传输成功率、传输时间和传输方向加权的路由协议算法;根据所设计的路由协议结构,将设计路由的具体实现过程分为路由发现、路由维护、路由应答以及异常处理四个过程;最后对无路由协议算法及采用设计的路由协议算法后的分组数据发送成功率和网络时延进行了仿真对比;仿真结果表明,数据的传输成功率明显升高,传输延迟有了一定的降低;该算法提高了系统资源的利用率,改进了现有的路由协议算法。

For the underwater acoustic communication characteristic of multiUUV formation control system, a routing protocol is pro posed based on the transmission ratio, transmission time and transmission direction weighted. According to the structure of the routing pro tocol, the implementation process of the routing process is divided into route discovery, route maintenance, route response and abnormity handle. Finally, the simulation results of no routing protocol＇ s data transmission ratio and network time delay and routing protocol＇ s data transmission ratio and network time delay is compared. The simulation results show that the success rate of data transmission significantly in creased, transmission delay reduced. The algorithm improves the system resource utilization and the existing routing protocol algorithm.
