Channel allocation problem in VoD system using both batching and adaptive piggybacking

Commercial feasibility demands that a large number of users should be accommodated in a VoD (video-on-demand) service with a certain level of QOS (quality of service) given a fixed bandwidth communication channel. Two novel methods to minimize the number of logical channels that are required to support as many users as possible are proposed. They are quasi-optimized batching-by-timeout and quasi-optimized batching-by-timeout with adaptive piggybacking. The effectiveness of the proposed channel allocation strategy is demonstrated by simulation
