An Adaptive VCT Based Handoff Scheme for Mobile Base Station in Wireless ATM network

As broadband multimedia services and wireless services become popular, it is believed that ATM is widely accepted as a backbone network. In a small cell radius structure, handover occurs more frequently as the mobile base station moves. Therefore, it is necessary to have high-speed handover control. To support network mobility, we introduce a new optimum handover scheme using the overlayered tree structure based on the virtual connection tree (VCT) for the handover involving several call connections. Then the handover delay could be reduced, we describe ATM signaling capabilities supporting this scheme and present UNI.NNI protocol extensions. According to simulation results of static and proposed adaptive VCT schemes in the circumstance of mobile network, proposed scheme has smaller handover delay compared with conventional schemes.
