A Priority-Based Adaptive Scheme for Wireless Multimedia Delivery

In wireless multimedia streaming, there is a need to allow for client prioritisation in order to enable provision of end user perceived quality in direct relationship with client device importance. Currently, the same priority is given to all clients, independent of their characteristics, often resulting in unfair distribution of throughput. This paper proposes a priority-based wireless adaptive multimedia delivery scheme that enables client prioritisation during multimedia distribution over IP networks. The paper presents simulation results outlining the benefits of applying the algorithm, illustrating the improvement in bandwidth allocation and in overall end user perceived quality. The algorithm focuses on a residential wireless local area network and assigns static priorities based on device characteristics
