| 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 realtime
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.
