On Resource Scheduling of Wireless Converged Broadcasting and Cellular Networks with Popular Services Being Preferentially Delivered
This paper studies on Resource Scheduling (RS) of Wireless Converged Broadcasting and Cellular Networks (CBCN) with popular services being preferentially delivered. In the proposed model of CBCN, the popular services are preferentially delivered by Wireless Broadcasting and Buffering Network (WBBN), and the other less popular services are delivered by Cellular Network (CN) with point-to-point (p2p) mode. With the help of return channels in CBCN, WBBN, which is the broadcasting part of the CBCN, can preferentially broadcast the most popular services to users. As a result, the efficiency of the CBCN is improved. The capacity of the WBBN is studied. We prove that the capacity of the WBBN subjects to Power Law distribution. The minimal time to schedule all the services in the CBCN is researched. Simulations show that we can properly choose the broadcasting bandwidth in the CBCN and the numbers of the most popular services to be delivered by the BN to minimize the scheduling time. Simulations also show the more popular of the services the larger broadcasting bandwidth is preferred to and the smaller of the minimal scheduling time of the CBCN.
