A new routing algorithm for micro-mobility by using core node

In order to provide fast handover, lots of micro-mobility protocols have been designed and proposed. However, they may cause excessive signal traffic and long latency for handover management. This paper proposes a new routing algorithm for micro-mobility scheme using core node. Core node handles routing information for a mobile host. It does not need to generate unnecessary control messages at each base station and wired node. We have conducted distribution of traffic as messages which create at the old BS and then disappears at the core node for maintenance of the routing table. We have evaluated the performance of our micro-mobility scheme through a series of simulations using the network simulator 2 (ns-2).
