    164157 1) Resource allocation with fairness.  With physical layer measurements, such as signal-to-noise ratio (SNR) over different sub-channels, optimal resource management can be performed in the MAC layer for SSs at different locations. We will implement several conventional schedulers, e.g., Modified Deficit Round Robin (MDRR) to efficiently support different types of WiMAX traffic flows (UGS, rtPS, nrtPS, Best Effort).  This work will focus on maximizing the overall system throughput, while assuring that each SS of predefined fairness in terms of data rate and delay constraint. [[BR]]
    165158 2)  Cooperative transmission (multihop).  One SS (here it may be a second BS or a virtualized second BS) may act as intermediate relay between an end SS and the BS. In the uplink, the relaying SS (second BS or a virtualized second BS) can intercept the signal from the end SS and then forward to the BS. Thus, the single-hop transmission is partitioned into two hops. By implementing and testing this function, we can show the performance enhancement of two-hop delivery over one-hop delivery in terms of either coverage extension or throughput improvement.[[BR]]
     
    170163 7)  Teaching purposes.  Finally we are planning to use the WiMAX facility for teaching classes on wireless networks, wireless video applications and for several labs.[[BR]]
