超短波电台通信网络中的自组网路由协议应用研究

针对临时组网通信过程中使用超短波电台作为常用的通信手段,讨论了自组网技术在超短波电台通信网络过程中,组网路由协议在实现高效组网和有效数据传输所起的关键作用。进而设计了一种适用于军事指挥、抗震救灾等野外临时性工作的应用场景,对不同自组网路由协议进行了比较研究,并通过仿真和评估测试路由协议在超短波电台通信网络中负载情况及数据投递情况,从数据投递率和归一化路由负载两方面对路由协议进行了性能比较和分析。实验数据表明,DSR协议的性能表现具有明显的优势,分组投递率高,路由负载较小,比较适合移植到超短波电台通信网络中使用。此外,AODV协议具有较小的路由负载,也可应用于低带宽的超短波电台通信网络。

RESEARCH ON APPLICATION OF AD HOC NETWORK ROUTING PROTOCOL IN ULTRA-SHORTWAVE RADIO COMMUNICATION NETWORK

This paper focus on the application of ultra-shortwave radio as a common means of communication in temporary network communication, discusses the function of ad hoc network technology in ultra-shortwave radio communication network and the key role of network routing protocols in efficient networking and efficient data transmission. Furthermore, this paper designs an application scenario which is suitable for field work such as military command and earthquake relief, and compares the performance of the routing protocols of different ad hoc networks. The routing protocols are compared and analyzed in two aspects:packet delivery fraction and normalized routing load, by simulating and evaluating load conditions and data delivery of routing protocol in ultra-shortwave radio communication network. The experiment shows that the performance of DSR protocol has obvious advantages, such as high packet delivery fraction and less normalized routing load, so it is more suitable for transplanting into ultra-shortwave radio communication network. In addition, AODV protocol has smaller routing load, which can also be applied to low-bandwidth ultra-shortwave radio communication network.
