Role Based Privacy-Aware Secure Routing in WMNs

Wireless Mesh Networks (WMNs) have drawn much attention for emerging as a promising technology to meet the challenges in next generation networks. Security and privacy protection have been the primary concerns in pushing the success of WMNs. However, the solutions proposed to ensure the security of the routing protocol and the privacy information in WMNs are still not robust. In this paper, we propose a role based privacy-aware secure routing protocol (RPASRP), which combines a new dynamic reputation mechanism with the role based multi-level security technology and a novel hierarchical key management protocol to defend against the internal attacks and to achieve better security and privacy protection. Simulation results show that RPASRP implements the security and privacy protection against the inside attacks more effectively and efficiently and performs better than the classical hybrid wireless mesh protocol (HWMP) in terms of packet delivery ratio.
