A network-based seamless handover scheme for multi-homed devices

Terminal-based mobility protocols require mobile devices to participate in mobility signaling that consumes lots of processing power and memory. Network-based mobility protocol solves this problem by excluding low-end mobile devices from signaling requirement. We earlier proposed SEMO6, a terminal-based mobility protocol which exploits multiple network interfaces to achieve seamless handover. In this paper, we have proposed a network-based mobility solution for SEMO6. We have performed a thorough cost analysis of its major mobility entities that participate in mobility management and also obtained their efficiency based on signaling overhead. Results show interesting relationships among various network parameters. Our signaling analysis can be used by network engineers to estimate the resource requirements of its entities in actual deployment.
