Admission control framework to provide guaranteed delay in error-prone wireless channel

An admission control mechanism is a key component of any framework that provides guaranteed delay service to heterogeneous real-time traffic. In this paper, we propose a general framework for admission control to provide delay guarantees in the error-prone wireless systems. By "general" we mean that the scheduling policies from a large class can be plugged in this framework and an admission control condition can be obtained for general arrival processes. The generality of the framework will enable us to use many scheduling policies that have not been considered yet for the error-prone wireless systems. The designed framework only assumes statistical knowledge of channel state and instantaneous knowledge of channel state is not required. Apart from providing delay guarantees in the presence of channel errors, the proposed framework provides (1) a good balance of packet drop and session blocking (2) isolation in the sense that once a session is admitted, then its guarantees (delay and packet drop) are not affected by other sessions.
