基于MAODV协议的网络编码方案

摘要

Currently the research of the network coding used in the Ad hoc multicast networks was lack, this paper proposed one scheme of network coding, used in the Ad hoc multicast networks based on MAODV protocol, and introduced the solving scheme of network coding to solve the question how to decode. These schemes applied network coding in Ad hoc multicast networks, and improved the network performance. Theoretical analysis and simulation results show that the two proposed schemes reduce the number of data packets, and reduce the consumption energy of node in Ad hoc networks.%目前网络编码在Ad hoc组播网络中的应用研究比较缺乏,针对这个问题,提出了一种在由MAODV协议(multicast Ad hoc on-demand distance vector routing protocol)组建的Ad hoc组播网络中使用网络编码的网络编码策略,并且为了解决如何解码的问题提出了网络编码处理策略,使得网络编码可以应用在Ad hoc组播网络中,提高了网络性能.理论分析和仿真结果表明,基于网络编码的Ad hoc组播网络与普通Ad hoc组播网络相比,减少了数据包发送次数,降低了网络能量消耗,保护了节点能量.
