摘要:

提出一种适用于无线多跳网络的基于地理位置的多阶邻节点辅助的编码感知路由协议(LFCR).LFCR基于数据流间编码思想,借助地理位置信息,在建立路由时,综合考虑编码机会和传输能够带来的数据包正向前进位移,在创造具有编码机会路径时,避免了路由过度绕远.仿真结果表明,相比于经典编码路由协议COPE,LFCR能够显著提高网络性能.

Abstract:

We propose a location-based multi-level-neighbor-assisted coding-aware routing protocol (LFCR) for wireless multi-hop networks. LFCR is based on the concept of inter-flow network coding and utilizes location information for establishing routes, which takes into account not only the potential network coding opportunities but also the positive progress brought by each transmission. Simulation results show that, compared to COPE, LFCR significantly improves performance of the network.

Key words: wireless multi-hop networks, location information, routing protocol, network coding
