Stream-based Traffic Management for Mobile Devices in Wireless LAN

Abstract

Nowadays, as a number of mobile devices are increasing rapidly, each user may use multiple traffics at the same time in wireless environment. The optimal traffic scheduling of mobile networks for multicasting and unicasting between various mixed mobile traffic is a challenging problem. Therefore, there are various researches concerning with traffic scheduling methods in order to have efficient transmission rate and to reduce traffic’s bottleneck at Access Point (AP) for mixed traffic. In this paper, the various scheduling methods in wireless network are analyzed and the framework of a new scheduling method, a two-step stream-based traffic scheduling method is proposed to satisfy efficient some Quality of Services (QoS) parameters: throughput, fairness and delay. In the first step, stream based scheduling adaptively balances between unicast and multicast traffic and in the second step, compound scheduling combines Proportional Fair (PF) for non-real time traffic and Delay Related Scheduling for real time traffic.
