Recommendation scheme based on converging properties for contents broadcasting

Popular videos are often clicked by a mount of users in a short period, and take most of the network traffic. With content recommendation, the popular contents could be broadcast to the potential users in wireless network, to save huge transmitting resource, as described in Content Aware Soft Real Time Media Broadcast (CASoRT) system. With the users´ communication log in the Chinese commercial cellular network, the contents propagation model is analyzed due to users´ historical behavior, location, and the converging properties in wireless data transmission is shown in this paper. Then, a recommendation scheme is proposed to achieve high energy efficiency in CASoRT system.
