A performance study on context-aware real-time multimedia transmission between smartphone and cloud

Due to the increasing amount of mobile devices such as smartphones and pads, the bandwidth requirements in the mobile networks are increasing exponentially. To reduce the traffic load between the smartphone and the application server on the cloud, we propose a context-aware mechanism where the smartphones and the network nodes report their contexts to the application server. The application server selects suitable video stream to deliver in order to reduce the bandwidth requirement and maintain good display quality.
