一种基于网络编码的Ad hoc网络多路径源选路由算法

A MULTIPATH SOURCE ROUTING ALGORITHM FOR AD HOC NETWORKS BASED ON NETWORK CODING

  • 摘要: 根据Ad hoc网络的特性,提出了一个基于网络编码的多路径源选路由算法.算法借鉴了COPE的思想,实现上通过在中间节点缓存短路径,对具有编码机会的中间节点进行标注,从而获得具有最大编码机会的多条路径.由于网络编码可以减少数据传输的次数,因此可以有效的提高信道的利用率.NS2环境下的仿真表明,新算法能够有效地平衡网络负载,提高网络的吞吐量.

     

    Abstract: According to the characters of Ad hoc networks, a multipath source routing algorithm based on network coding is presented. The algorithm refers the idea of COPE. In realization, the multiple paths that have maximum coding opportunity are found by caching short paths in medium nodes and labeling the medium nodes that have coding opportunity. Because network coding reduces data's transmission times, the algorithm can improve channel utilization effectively. Simulations under NS2 environment prove that the new algorithm has better performance in balancing the network load and improving network throughput.
