Secure and Multihomed Vehicular Femtocells

Operators must ensure seamless voice and data session continuity even when subscribers are on move. Service continuity is one of the most critical quality parameter in a cellular system. QoS during handover is always hindered by the handover latency and packet loss. Among several approaches, IP multihoming is a promising solution to achieve throughput increment and packet loss reduction. Theoretically, it can ensure no interrupt or packet loss during the handover. In this paper, we present a novel Host Identity Protocol (HIP) based secure vehicular femtocell scenario. For the evaluation, we have developed a simulation model on top of HIPSim++ framework (simulation framework for HIP) integrated into INET/OMNeT++. Finally, we investigate the feasibility to use HIP in a vehicular femtocell which is new in the context and measure the performance in terms of handover latency, packet loss and throughput to compare multihomed and singlehomed communication.
