Abstract

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.
