Abstract

Wireless ATM(WATM) is expected to provide significantly high bit-rate services to meet the demand for handling multimedia information. In a mobile wireless environment, hand-off provisioning is a challenging problem and much effort has been contributed for efficient utilization of the limited radio resources. In this paper, we propose a capacity maximization method in a multimedia Wireless ATM system, which can be used for handoff prioritization by bandwidth reservation. Specifically, we propose to regulate the buffer by the Selective-delay Push-in (SDPI) scheme, and search for the optimal percentage of total bandwidth to be reserved for handoffs. Simulation results show that our scheme significantly improves spectrum efficiency and reduces handoff failure probability.
