Abstract
Future mobile communication systems can support not only voice but also multimedia applications such as data, image and video. It requires greater resources than voice-oriented mobile system. If handoff events are occurred during the transmission of multimedia, the efficient resource reservation and handoff procedures are necessary to maintain the same QoS of transmitted multimedia traffic because the QoS may be defected by some delay and information loss. This paper proposes a resource reservation scheme to accommodate multimedia traffic based on the direction estimation in Mobile Multimedia Networks (MMNs). This proposed scheme estimates the position of mobiles based on a two step estimation comprised of sector estimation, zone estimation. With the position information, the moving direction is determined. Through simulation results, we show that our proposed resource reservation method provides a better performance than the previous methods.
