Adaptation of Cloud Resources and Media Streaming in Mobile Cloud Networks for Media Delivery

Abstract

Multimedia content delivery is one of the use cases of Mobile Cloud Networks. Cloud Networks are then called Media Clouds. Since mobile devices are becoming increasingly important receptors of Multimedia content, Mobile Cloud Computing is undertaking an important role for delivering Multimedia content from the Cloud through the Internet towards the Mobile users. On the other hand, high requirements of Multimedia content streaming establish the necessity of crossp-layer mechanisms for avoiding or decreasing the effects of, for example, mobile network congestion or cloud congestion. This chapter introduces an exemplary solution, at the application layer, which takes into account the state of the network for efficient Media streaming in Mobile Cloud networks (Media Mobile Cloud). Concretely, the presented solution proposes a novel adaptation algorithm that adapts not only Media bitrate in the case when there is a congestion in Mobile last mille, but also adapts Media content source when the Cloud suffers from congestion.
