Accounting for Uplink Traffic in the Design of Schedulers for Multiple Traffic Classes in OFDMA Networks
The research literature in wireless networks contains many examples of proposed MAC protocols. Every such proposed protocol thoroughly addresses downlink traffic from the Base Station (BS) to the Mobile Station (MS). Few, if any, do more than mention uplink traffic. In this paper, the authors look at two MAC protocols, multiclass MLWDF and joint scheduler, from the perspective of uplink traffic in addition to downlink traffic. In recent years that has been a great deal of activity in the area of research and standardization of mobile wireless networks.
