Media-aware proxy: Application layer filtering and L3 mobility for media streaming optimization

The explosive growth of new multimedia applications over mobile networks has attracted intensive research over the years. The main problem in this area is posed by the immense data rate required for multimedia applications in conjunction with the scarcity of wireless resources. To alleviate this shortcoming, this paper proposes combining mobility management and application layer filtering in order to optimize and maintain video quality. The design of the proposed solution is described in depth, as well as the integration of this approach within the LTE Evolved Packet Core architecture. Finally, experimental results are presented to demonstrate the performance of the proposed mechanism.
