摘要: 针对当前大多数据传输协议没有充分利用无线信道的广播特性这一问题,本文提出了基于网络编码的机会路由协议NCOR(Network Coding based Opportunistic Routing protocol).首先,通过分析网络端到端传输代价,本文提出了最优转发集构造机制以最小化传输代价.此后,NCOR在转发集内执行节点协作式编码传输以保证传输可靠性.最后,理论分析了NCOR的传输可靠性结论.仿真实验表明NCOR可适用于不同的链路环境,且在保证可靠传输的同时,大幅降低了网络能耗.

Abstract: At present, most data transmission protocols do not make full use of the broadcast nature of wireless channels.To address this problem, this paper proposes a network coding based opportunistic routing protocol (NCOR). Firstly, by analyzing the end-to-end transmission cost of the network,a mechanism for constructing the optimal forwarding set is proposed to minimize the transmission cost. Then, NCOR performs cooperative coding transmission among nodes in the forwarding set to ensure transmission reliability. Finally, the transmission reliability of NCOR is analyzed theoretically. Simulation results show that NCOR can be applied to different link environments, and it can greatly reduce the network energy consumption while ensuring reliable transmission.
