Jitter Detection for Connection-Level and Packet-Level QoS support in Mobile Multimedia Networks

Multimedia traffic which are generally VBR in nature require efficient adaptive resource allocation schemes when supported over Mobile Networks. Admission control schemes that satisfy the desired/guaranteed QoS for multimedia applications under different traffic loads to achieve high utilization need to be designed. Packet level QoS parameters include delay, packet loss probability and jitter while the connection level QoS parameters are those related to connection establishment and management. Jitter is a packet-level QoS parameter that models the degradation in the timing relationship among packets in a single media stream and between packets from different media streams and could create problems in multimedia synchronization. In this paper we have proposed a Jitter Sensitive Dynamic Admission Control(JSDAC) scheme that dynamically adapts itself based on its packet loss and jitter tolerance capability during admission control, thus ensuring better Quality of Service(QoS) Support.
