A Wireless Multicast Opportunistic Routing Based on Double Direction Network Coding

  • 摘要: 针对现有机会网络编码中存在的编码机会依赖于不同数据流间的连接节点个数和编码效率等问题,结合机会通信和网络编码的特点提出一种新的路由解决方案.首先在传统无线路由算法中引入流内编码和流间编码的概念,并设计合理的网络编码策略和响应机制,以提高编码的机会和网络的吞吐量等性能.仿真实验显示,新的优化算法可显著提高网络的吞吐量和编码增益.

     

    Abstract: A practical multicast routing is presented, which utilizes the broadcasting nature of wireless signaling to create coding opportunities for the wireless network.The proposed algorithm increases the opportunities for coding by applying dual network coding, an Intel-flow coding and an Intra-flow coding scheme. The simulation shows that the proposed algorithm is a better multicast routing by comparing with none coding algorithm and MORE-M in terms of coding gain, transmission reduction and throughput.
