Abstract

Present mobile multimedia networks have different Quality of Service (QoS) requirements for diverse applications starting from voice to Multi Media Services (MMS) with major objectives such as better admission control, effective bandwidth utilization, support for real- time and non- real time applications content transfer, mobility etc. So the network aims at satisfying their demands without much degradation of quality in terms of delay call dropping and call blocking. It is possible by admission control algorithms and by optimizing the existing resources in an effective way. It improves the overall performance of the network system. This paper addresses different Quality of Service (QoS) requirements of the users of a cellular network with a focus on fuzzy based Call Admission Control Scheme (CAC) and optimized bandwidth allocation using Linear Programming (LP) analytical model. For comparison, Meta heuristic technique- Simulated Annealing (SA) is also used. We propose a novel combined framework model to address resource allocation problem. This problem can be dealt with two critical issues in a cellular mobile multimedia networks namely Admission control and Transmission control. The admission control – the decision to admit or reject the calls based on fuzzy logic concepts. Transmission control – Bandwidth allocation using LP technique and SA method. We demonstrate the efficiency of the proposed framework model by combining fuzzy based admission control scheme and optimized techniques in bandwidth allocation, which provide better QoS differentiation and efficient usage of scarce radio resource such as bandwidth in multimedia cellular networks.

 Keywords: Call admission control, fuzzy logic, bandwidth allocation, linear programming, QoS, simulated annealing.
