Abstract
The increasing demand for multimedia services combined with the resource constraints of the wireless networks indicate the need of efficient admission control schemes to achieve a complete resource management combined with adequate quality of service(QoS) levels for end users. QoS provision in wireless networks is closely related to the exploitation of available network resources and the maximization of the number of users. Call Admission Control(CAC) is one of the key issues in wireless mobile communications, concentrating great interest in research work about QoS. CAC algorithms are employed to ensure that the admission of a new call into a resource limited network does not violate the Service Level Agreements concerning ongoing calls.
