摘要

网络编码为提高无线网络的性能提供了一种强大的机制。本文研究了MAC协议对无线网络编码性能的影响。为了对MAC协议进行建模，我们引入了一个虚拟的无线网络拓扑图(DTG)，它可以很好地描述无线信道的广播特性。在DTG的基础上，利用网络演算理论推导了计算流的端到端延迟的理论公式。数值结果表明，MAC协议的公平性有助于提高无线网络编码的性能。

Effects of MAC protocols on the performance of wireless network coding

Network coding provides a powerful mechanism for improving performance of wireless networks. In this paper, we study the effects of MAC protocols on the performance of wireless network coding. To model the MAC protocols, we introduce the dummy topology graph (DTG) of a wireless network that can properly describe the broadcast property of wireless channels. Based on the DTG, we derive theoretical formulations for computing the end-to-end delay of flows using the theory of network calculus. Numerical results show that the fairness of the MAC protocols can help to improve the performance of wireless network coding.
