DCA Schemes For Differentiated Qos In Microcells

This paper investigates in a microcellularset-up the behavior of a new class of dynamic channelallocation policies, tailored to provide different QoS degreesto distinct user classes of a wireless system. Theperformance achieved by a network employing theseschemes is evaluated in terms of call blocking, taking intoaccount the requirements raised by multi-rate applications.Some design criteria effective to optimize the managementof the scarce radio resources are furnished andthe goal of providing radio users with both low and highspeed connections, suitable for a basic set of audio andvideo applications, is achieved
