Wireless multimedia applications are major services of next generation wireless networks. This paper is one of the first to study the efficient utilization of network resources for increasing the number of concurrent multimedia flows when a channel becomes saturated. The authors theoretically study the flow scheduling policy with the motivation of ameliorating the trade-off between limited channel resources and multiple flow transmission. Based on the dynamic states of wireless channels and the profile of multimedia flows, the policy fully utilizes the performance gap for increasing the number of performance guaranteed multimedia flows, by scheduling multiple flows in turn without interference.
