随机网络编码具备提高无线传感器网络的传输可靠性,降低网络能量消耗等特点,其应用设计缺少网络仿真验证方法。在OMNET++仿真平台上设计了数据包缓存处理机制,并实现了有限域编码运算。在此基础上设计了独立于其他节点模块的随机网络编码模块,将其添加到网络节点模型中。使用该网络节点模型建立传感器网络,在多路径路由方式下,对应用随机网络编码模块前后数据包传输可靠性、延时和有效吞吐量网络特性进行评估,为设计应用随机网络编码提供一种仿真设计思路。
Abstract：The application of RNC( Random Network Coding) can improve the transmission reliability and reduce energy consumption for wireless sensor network. But network simulation method is lacking for the application and design of RNC. Packets buffer mechanism is designed and finite field calculation is implemented on OMNET + + platform. Based on this work,a RNC module is designed,which is independent of other node modules. The RNC module is applied into network node model which is used to establish a sensor network. Applying multipath routing,the packet transmission reliability,delay and efficient throughput are evaluated with / without application of RNC. Our work provides a network simulation method for the application of RNC.
