Anonymous Communication Scheme for Wireless Mesh Network Based on Network Coding

Abstract

Wireless Mesh Network, holding the features of self-organization, strong scalability, low deployment
cost, is considered to be the most competitive technology for broadband wireless access service.
However, the security and privacy issues become the bottleneck for WMN’s rapid popularization.
Network coding, which can improve both network throughput and anonymity, is adopted for the
communication security in WMN recently. However, the related network-coding based anonymous
communication schemes suffer from the efficiency and security issues. In this paper, an efficient
anonymous communication scheme for WMN is proposed, which combines the opportunistic routing
protocol and network coding approach. The global coding vector is protected with the lightweight
permutation encryption mechanism. In addition, the security and performance analysis demonstrate
that the proposed scheme can provide strong privacy protection for WMN communication with high
network throughput.
