A new micro-mobility scheme using core node in all-IP-based wireless systems

This paper proposes a new micro-mobility scheme using core node. This node manages routing information for a mobile host and not to generate unnecessary messages at each base station and wired node. This scheme can prevent control traffics from all networks and reduce packet loss & handover latency because these messages can be sent to only the core node. We have conducted distribution of traffic as messages which created at old BS and then disappeared at core node for maintenance of routing table. We have evaluated the performance of our micro-mobility scheme through a series of simulations using the Network Simulator 2 (ns-2).
