Multihoming and mobility protocols enable computing devices to stay always best connected (ABC) to the Internet. The focus of our study is on handover latency and rehoming time required by such protocols. We used simulations in OMNeT++ to study the performance of the following protocols that support multihoming, mobility or a combination thereof: Mobile IPv6 (MIPv6), Multiple Care-of Address Registration (MCoA), Stream Control Transmission Protocol (SCTP), and Host Identity Proto- col (HIP). Our results indicate that HIP shows best performance in all scenarios considered.
