Abstract: Network coding can greatly improve the throughput of network and reduce average end-to-end delay.But previous network coding schemes’ complexity made themselves difficult to be implemented.Meanwhile,as a special network,Ad Hoc’s secure routing protocol is a hot research area.This paper introduces a simple network coding scheme to improve the performance of SAODV a better secure routing protocol in Ad Hoc network.The scheme is easily realized,involves no complicated coding,and has big utility value.

Key words: network coding, Mobile Ad Hoc network, Secure Ad Hoc On-demand Distance Vector(SAODV) routing protocol

摘要: 网络编码可大大提高网络吞吐量、减少延迟。然而,由于编码意义上网络信息流的复杂性,实际应用中仍存在困难。另一方面,Ad Hoc网作为自组织形式的特殊网络,其安全路由协议是研究重点。针对Ad Hoc网安全路由协议中较优秀的SAODV,提出一种基于网络编码的优化方案,较传统编码易于实现、具有较强实用性。
