Abstract

This paper is to study how to realize the seamless inter-AP handoff for the express mobile gateway on the train, which not only must execute the handoff rapidly, but also have to make the handoff decision quickly. Hence, the special and general inter-AP handoff concepts presented firstly and then a general inter-AP handoff model is built up. Based on this model, a radio-signal-measurement based handoff decision model and a multiinterface based rapid handoff algorithm are designed, which can decrease the network disrupt time to several milliseconds and maintain the link quality all the time while the EMG is fast moving along the serial APs.
