摘要: 通过研究在无线网络中分别处于不同节点内的独立信息源,如何利用网络编码进行更加有效、可靠的信息交换,证明了网络编码技术的引入对信息交换过程中的网络吞吐率和鲁棒性的改善。基于此结论,设计了一种无线网络中基于网络编码的多源间信息交换方案,量化地分析了该方案对网络性能的提高,并提出了一种该方案在实际无线网络环境中的分布式应用策略。

Abstract: This paper shows that mutual exchange of independent information between nodes in a wireless network can be efficiently performed by using the network coding technology. Based on this conclusion, this paper provides a method for multi-source information exchange in wireless networks with network coding and analyzes the improvement of the network performance, including a better robustness and a higher throughput, introduced by this method. This paper also proposes a distributed scheme of this new method for the practical application.
