Scheduling method for a real time data service in the wireless ATM networks

Abstract

This paper proposes an improved Traffic-Controlled Rate Monotonic (TCRM) priority scheduling algorithm as a scheduling method in order to transmit real-time multimedia data in a wireless ATM networks. A real-time multimedia data transmission scheduling policy is applied using a different method to uplink or downlink states according to the wireless communication environment, and guarantees the requirement of QoS for both real-time and non-real-time data. In addition, it deals the issue of fairness to share and distribute insufficient wireless resources. Moreover, an issue of inefficiency for non-real-time data, which is a demerit of a TCRM, can be solved using an arbitrary transmission speed by configuring a Virtual Control (VC) in a Base Station (BS). © Springer-Verlag Berlin Heidelberg 2005.
