| 摘 要： | 传统网络编码方案使用固定的传输速率,没有考虑传输速率自适应对网络性能的影响,使得无线网络的性能不能进一步提升。文中提出一种基于传输速率自适应的网络编码协议,使得网络中的节点可以根据数据传输特性和无线链路质量作出路由决策,充分利用网络中空闲节点的传输能力,有效降低了节点间的通信开销,减少了重复数据包发送的概率。仿真结果表明,优化后的路由协议能够有效提升网络的吞吐量同时降低包的端到端时延。

| Abstract: | Traditional network coding scheme adopts a fixed transmission rate without considering the impact of diverse rate on the performance of the network,which limits the performance of wireless network.Thus,a network coding scheme based transmission rate adaptation routing protocol TRANC for wireless mesh network was proposed,in which each node makes the routing decision according to the characters of data transmission and the wireless link quality,making full use of the transmission capacity of idle nodes in th... |
