中文摘要：

在无线网络中利用信号的全向传输特性,结合网络编码技术可以提高信道的传输效率。然而无线传输过程中链路的不可靠性会造成分组传输失败,进而影响无线传输的效率。针对该问题提出一种传输算法并且进行仿真验证。该算法根据传输业务的时延要求动态管理缓存队列,并且根据网络链路状态判断是否进行基于网络编码的传输,使网络的吞吐量在网络业务传输时延可接受的范围内达到最大。

Abstract： In wireless networks, the coexistence of signal＇s omnidirectional transmission characteristic and network cod- ing technique can improve the transmission efficiency in wireless channels. However, the transmission efficiency would decrease due to the potential failure of packet transmissions in unreliable wireless transmission links. To address this problem, a novel transmission algorithm was proposed, which was verified in the conducted network simulation. Particu- larly, the proposed algorithm can dynamically manage the buffer queue according to the delay requirements of specific transmission tasks, and decide whether encoding the transmission based on the network link status. The simulation results demonstrate that the proposed algorithm can maximize the network throughout capacity with the acceptable network transmission delay.
