基于网络分簇和多路径的无线自组织网络匿名通信协议

Cluster-based Multipath Anonymous Routing Protocol in Wireless Ad Hoc Networks

提出了基于网络分簇和多路径的自组织网络匿名通信协议(CMAR),该协议中节点首先在不暴露身份信息的情况下,利用双线性配对技术生成和邻居节点共享的密钥,并以此为基础,秘密地建立用于成员节点和簇头节点之间通信的簇内路由表项,在簇内路由表项的辅助下,完成源节点和目标节点之间多路径的匿名建立,以及数据报文的匿名转发。通过性能分析可以发现,CMAR协议的密码学运算负荷较低,且网络通信性能良好。

Without disclosing the real identities of participating nodes, the shared session keys and secret link identifiers among neighbors are exchanged based on bilinear pairing, and further the local anonymous routing entries between the normal nodes and cluster head are built. With the help of local anonymous routing table, multi-path between source-destination can be constructed and data packets will be anonymously forwarded to destination along these paths. Simulation results show that CMAR achieves perfect anonymous communication with relatively low cost of communication and computation overhead.
