On intra- and inter-session channel provisioning for video distribution in wireless networks with heterogeneous users

This paper presents a formal study on channelized bandwidth resource provisioning for multi-rate and multi-session video broadcast in a broadband wireless network with heterogeneous users. The formulation is generic in that it considers both inter-session and intra-session wireless resource allocation. It also takes into account the most fundamental issues associated with video transmission including encoding complexity, transport overhead, non-linear relationship between the receiver perceived video quality and the delivered bandwidth, and intra- and inter-session fairness. In addition, we derive an optimal allocation scheme to manage the scarce wireless resources
