Distributed order queuing and dynamic bandwidth allocation for QoS control in CDMA system
M. Ogawa, T. Sueoka, Takahiro HATTORI · 2002
The introduction of QoS (quality of service) control is demanded in wireless networks. A reserved MAC protocol with QoS scheduling is necessary in order to satisfy user demands, because mobile terminals send packets of various lengths at random in the uplink (mobile terminal to base station). We define QoS as allowable delay time in the uplink and propose a new QoS control scheme for CDMA. The proposed scheme is composed of distributed order queuing and dynamic bandwidth allocation. Simulation results show that the proposed control guarantees delay time and the performance is better than priority queuing.
