基于网络编码的无线路由技术研究进展

网络编码是近年来通信领域所取得的重大进展之一,其核心思想是网络节点对于接收的分组不是采取的传统的存储-转发的简单路由方式,而是存储-编码处理-转发的方式。网络编码已被证明是改善无线网络性能特别是吞吐量性能方面的下一代关键技术之一,特别适合战场环境下广播和组播信息的高效传输。本文综述了近年来基于网络编码的无线路由技术的相关研究进展,分析了现有研究的局限性与不足,并对下一步研究方向进行了展望。

A Survey of Network Coding in Wireless Networks Routing Protocols on Throughput Gains

The Network Coding is one of the most important progress in recently years in field of communications. The core idea of Network Coding is that every node in a network doesn＇t function as a switch which just forwards the packets after it has received several packets, but it has the ability to code packets before forwarding. The Network Coding has been proved as one of the key technologies to improve the performance of wireless networks especially for the transmission of broadcast or multicast information in tactical environment..This paper focuses on latest research results of network coding which combined with network layer in wireless networks to increase throughput gains. In conclusion, the shortages of existing researches are pointed out, and some suggestions for future research work are proposed.
