An integrated system for QoS provisioning in cellular networks

Abstract

One of the most challenging issues for next generation cellular networks is the provision of Quality of Service (QoS) guarantees to the high number of multimedia applications with different Service Level Agreement (SLA). To improve the utilization of network resources and facilitate management and control, source types are organized into different traffic classes. Each traffic class requires different treatment from the network in terms of allocated bandwidth, delay, jitter, and packet loss. Due to this, traffic classification/differentiation is a main issue in network level QoS. Hence it is required to analyze the issues related to the design of AC, service class differentiation, scheduling mechanisms and compensation scheme. This paper proposes a framework for QoS provisioning and also considers how the key requirement of coexistence between fuzzy based admission control, scheduling and compensation technique could be accommodated in a cellular network system with experimental results.
