We propose an optimistic quality-of-service (QoS) provisioning scheme for multimedia traffic in wireless networks. The scheme uses the standard classification of network traffic into two priority classes based on their bandwidth requirement and delay tolerance. We classify the users as local or departing based on their current coordinates in the cell. A call admission algorithm, a call management algorithm and a prediction based resource reservation algorithm which reserves the specified bandwidth (by borrowing channels from neighboring cells, if required) in the predicted destination cell(s) of a departing user are presented. A novel approach called bandwidth compaction is proposed which enables more efficient spectrum utilization. Simulation experiments show improvements of about 24% in the call blocking probability and 12% in the connection dropping probability over other bandwidth reserving schemes. An overall improvement of 24% in bandwidth utilization over other schemes not employing any bandwidth management technique, is also observed.
