QoS Based Adaptive Admission Controller for Next Generation Wireless Networks

Executive Summary

In 4G networks admission control will need to deal with many heterogeneous networks and admit new sessions to a network that is most appropriate to supply the requested QoS. In order to avoid the degradation of the QoS of low priority sessions, in this paper the authors propose a QoS Based Adaptive Admission Controller (QAAC). The service request is classified into two types new or handoff and the traffic is classified as real-time and non real-time. Then depending on the traffic class and type of service, the request is finally classified into four categories and priorities are assigned for each category. The admission control algorithm manages the various service requests in their queues and adaptively schedules them as per their assigned priorities.
