Call admission control (CAC) is a key factor in quality of service (QoS) provisioning for adaptive multimedia services in high-rate WPAN. In this paper, three functions, namely bandwidth satisfaction function, revenue rate function and bandwidth reallocation cost function, are firstly introduced. Based on these functions, a simple and efficient CAC scheme: reservation-based and revenue test CAC with bandwidth reallocation (Rev-RT-BRA CAC) scheme is proposed. The main idea is that it reserves some bandwidth for service classes with higher admission priority. The performance of the Rev-RT-BRA CAC scheme is analyzed by solving a multidimension Markov process. Both the numerical and simulation results are given. The advantages of the proposed Rev-RT-BRA CAC scheme are as follows, (i) It maximizes the overall BSF at any system state, (ii) It solves the unfairness problem in admitting multiple classes of services with different bandwidth requirements, (iii) The required admission priority level can be guaranteed for various classes of service.
