【摘要】：针对采用Epidemic机制的机会网络路由算法在数据分组传送阶段存在通信冗余的问题,提出了一种基于网络编码的高效路由算法——NCBER(network-coding-based epidemic routing)。NCBER在传送数据分组的过程中使用主动异或网络编码和多播,并取消了Request(请求)控制分组,从而减少数据分组的转发次数和控制分组数量,降低网络开销,缩短分组传输时延。理论分析和仿真结果表明,NCBER算法在网络开销和数据分组端到端时延性能方面优于经典的Epidemic路由算法及其改进算法MRRMR(message redundancy removal of multi-copy routing),并且使数据传送成功率保持在100%。
[Abstract]:Aiming at the problem of communication redundancy in the data packet transmission phase, the opportunistic network routing algorithm based on Epidemic mechanism is proposed. In this paper, an efficient routing algorithm based on network coding is proposed. NCBER-network-coding-based epidemic routing).NCBER uses active XOR network coding and multicast in the process of transmitting data packets, and cancels the request control packet. In order to reduce the number of data packets forwarding and control the number of packets, reduce the network overhead, The theoretical analysis and simulation results show that the NCBER algorithm is superior to the classical Epidemic routing algorithm and its improved algorithm, MRRMR(message redundancy removal of multi-copy routing, in network overhead and end-to-end delay performance of data packets, and makes data transmission. The success rate is kept at 100.
