Optimization of Broadcasting Scheme for the CASoRT System

Content Aware Soft Real Time Media Broadcast (CASoRT) is a new solution for information service of cellular network. As the similar distribution of user´s interest, the data of same content may be accessed and retransmitted frequently in cellular network during certain period of time, which caused the dissipation of both energy and spectrum efficiency. With the development of Data Mining, the CASoRT system could discovers the user´s common interests and broadcast such content to users who may be interested in. With those users accessing the content locally, the poential retransmission could be avoided and thus it could save energy from carrier´s view while providing the same real time experience to the users. In this paper, we propose a set of algorithm for the optimization of broadcasting scheme for the CASoRT system to achieve more energy efficiency.
