Abstract :
We propose a new framework called dynamic adaptive quality of service (DAQoS) to guarantee the quality of service (QoS) of multimedia traffic generally classified as Constant Bandwidth Service (CBS) and variable Bandwidth Service (VBS). DAQos implements a traffic-based admission control, bandwidth reallocation and reservation schemes to support multimedia traffics. The objectives that DAQoS framework tries to accomplish are minimum new call blocking and handoff dropping rates. This scheme is developed to control the bandwidth operation of ongoing connections when the system is overloaded. VBS can borrow bandwidth from CBS when CBS have spare bandwidth, and can give back in times to avoid call drop and block.
