Description
Summary:In this paper, the performance of dynamic resource allocation and channel de-allocation in integrated voice/data wireless networks with link adaptation is mathematically analyzed and evaluated. To our knowledge, all previous related works published in the literature have considered only link adaptation (LA) or dynamic resource allocation (DRA) separately. Additionally, a DRA strategy with link quality-aware prioritized channel de-allocation (called DRA LA DAS) is proposed. With the DRA LA DAS scheme that calls with the greatest number of channels and the worst link quality are degraded first. In this way, in DRA LA DAS preference is given to data users with good quality link which, on average, retain resources less time than data users with bad quality link. Numerical results show that the proposed DRA LA DAS strategy significantly improves system performance. The GSM/GPRS system is used as a case study. The GSM voice new call blocking and forced termination probabilities, GPRS packet dropping probability, average GPRS packet transmission time, and channel utilization are analyzed
