Utility Based Model for Optimized Resource Allocation for Adaptive Multimedia Services

The problem of dynamic Quality of Service (QoS) management for multimedia services has been addressed from two complementary, yet interrelated directions ; one mainly dealing with designing adaptive or “elastic” services, and the other, dealing with “smarter” resource allocation. We adopt this approach in this paper, by performing a graceful quality degradation and the corresponding resource (re)allocation for multiple multimedia sessions in case of decreasing network resources. We introduce a mathematical model which optimizes overall system utility by taking user satisfaction and operator profit into account.
