(English Abstract) |
This paper presents a dynamic connection admission control (CAC) algorithm for adaptive multimedia services. The proposed algorithm is mainly devoted to finding the best possible QoS levels for all the connections (i.e., QoS vector) that maximize resource utilization by fairly distributing wireless resources among the connections while maximizing the statistical multiplexing gain (i.e., minimizing the blocking and dropping probabilities). The problem itself is formulated as a multi-objective optimization problem. The algorithm employs a Hopfield neural network (HNN) for finding the QoS vector. Hardware-based HNN exhibits high (computational) speed that permits real-time running of the CAC algorithm. Simulation results show that the algorithm can maximize resource utilization and maintain fairness in resource sharing, while maximizing the statistical multiplexing gain in providing acceptable service grades. Furthermore, the results are relatively insensitive to handoff rates.
