An Efficient Trusted Mobile Router Selection Mechanism for Multihomed NEMO Network

The Network Mobility (NEMO) Basic Support protocol enables support for network mobility for MIPv6 networks, and multihoming technology provides support for multiple mobile routers (MRs) in one mobile network. Due to the critical role in acting as a gateway, the MR is particular vulnerable to various internal and external attacks, even being penetrated and controlled. The mobile nodes (MNs) attaching to a malicious or compromised MR will be under serious security threats. To protect the security of mobile nodes, we propose an efficient trusted MR selection mechanism in which a membership-clouds based trust model is presented for evaluating the trustworthiness of MRs. In the trust mechanism, most of the trust management tasks are assigned to the home agent (HA) that is a fixed router to save the resources and energies of mobile nodes. Simulation results show the effectiveness and efficiency of the proposed mechanism.
