A Novel Packet Level Scheduling Using Class Level Qos In Wireless Systems

摘要

The Wireless Access System is an emerging trend. The sharing of resources in such systems is a complex one due to its heterogeneous nature. Thus Quality of Service in such systems is a crucial one. In this scheme a class based packet scheduling algorithm is proposed. The proposed scheme employs practical economic models through the use of novel utility and opportunity cost functions to simultaneously satisfy the diverse QoS requirements of the mobile users and to minimize the revenue loss of the network operators. Unlike the existing scheme, the proposed scheme is general and can support multiple QoS classes with the users having different QoS and traffic demands. It minimizes the revenues of the network operators. When compared to existing schemes, the proposed scheme satisfies the Quality of Service on different demands such as traffic and user counts. This supports three conditions of traffic situations such as best effort traffic, traffic with minimum data requirements, and traffic with maximum data requirements.
