A controllable privacy protection framework in position-based routing for suspicious MANETs

The privacy protection is an important issue for suspicious MANETs, a kind of Mobile Ad-hoc Networks (MANETs) that the nodes do not trust each other. One vital problem of the privacy protection in suspicious MANETs is that the malicious nodes may abuse the privacy protection to initiate some attacks that can not be tracked. As a solution to this problem, this paper proposes a universal controllable privacy protection framework in position-based routing for suspicious MANETs. We integrate a Perturbation-based Privacy Preservation (PPP) mechanism and a Malicious Node Revocation (MNR) mechanism with the common position based routing protocols, and achieve the controllable privacy protection to nodes and the controllable security of networks. The analyses show that our framework can achieve the node control location privacy of the nodes, and can defend the malicious insider nodes and impersonation attacks with acceptable overheads in suspicious MANETs.
