OPTIMIZATION OF ON DEMAND SERVICE PROVISIONING WITH MULTICAST COST SHARING
In this paper, a dynamic scheduling scheme is proposed for delivery of on demand multimedia contents (e.g. movies) for internet service providers (ISP). The ISP is interested in assigning available resources to the requests in such a way that the lead time remains lower than a threshold, and the profit is maximized. Therefore, since the ISP dynamically receives the requests, postponing transmission of videos to some customers can provide the opportunity to increase the profit by reducing cost of distribution paths via multicast cost share without violating delivery time constraint. Performance of the proposed heuristic algorithm is evaluated and compared with a popularity based scheduling algorithm for a wide range of parameters via extensive simulation experiments.
