N2 - In this paper, the modified weighted g-fair (MWGF) scheduling scheme with rise over thermal (RoT) filling is proposed for QoS guaranteed services in DS-CDMA uplink networks, in which RoT is directly related to the loading factor of a wireless network. The proposed scheme computes priorities of QoS guaranteed traffic for each slot based upon the weighted values of the QoS factor, channel factor, and fairness factor. Once priorities are assigned, power and rate used for each user are computed within a limited RoT by using RoT filling, which adjusts the transmit rate of the traffic assigned least priority. The proposed algorithm increases more throughput by 6 to 10 % compared to that of the current autonomous rate control (ARC) scheme. It also lowers transmission delays and ensures more fairness in delay outages than the round robin scheduler and ARC scheme.
