Efficient Resource Utilization for Multi-Flow Wireless Multicasting Transmissions

Wireless multimedia services are major applications 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 and the channel aggregation policy in both single-hop and multi-hop wireless networks with the motivation of ameliorating the trade-off between limited channel resources and multiple flow transmission. To increase the number of performance guaranteed multimedia flows, based on the dynamic states of wireless channels and the profiles of multimedia flows, the two policies fully utilize the performance gap to schedule concurrent flows for transmission in turn and aggregate multiple channels' residual capacities for useful flow transmissions.
