    154 3)  Locations service, assuming multiple WiMAX BSs.[[BR]]
    156 Columbia Univ (1770): ?  [[BR]]
    158 NYU Poly (1751) on 3/17:[[BR]]
    159 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]]
    160 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]]
    161 3)  Cooperative Multicast real-time services.  We will study the performance of multicast services in different setup of the testbed. We will measure the PER in different locations and study several schemes for the improvement of the QoS in different groups of stations, including cooperative schemes where particular clients will operate as relays and will forward the multicast streams to groups of stations with poor link quality. Video over wireless schemes will be developed and tested where application layer FEC or/and layered video schemes will be implemented. [[BR]]
    162 4)  Rate adaptation.  We can test rate adaptation function in the open-source MAC layer driver. In response to the variation of physical layer channel, we can adjust the transmission rate of each SS adaptively such that a certain level of QoS can be guaranteed while the optimal data rate is maintained over time.[[BR]]
    163 5)  WiMAX/WiFi interconnection.  Based on the fact that in the same Lab we operate a WiFi testbed similar to ORBIT, we are planning to investigate the dynamics of coexisting WiMAX and WiFi testbeds. In particular, we are planning to develop schemes where the clients of the network have two interfaces: one WiMAX and one WiFi. The clients are located relatively close to each other (in the same building) and they receive a video stream from the WiMAX BS. However, each client experiences different video quality due to the different packet errors at different locations. In order to improve the video quality, the clients setup an ad-hoc WiFi network. Each client buffers the video stream and figures our which packets are missing in a particular time window. Then it broadcasts requests to the ad-hoc network asking for the missing packets. Nodes that have those packets, reply by sending them to the node that initiated the process. In this way the wireless nodes recover the packets lost in their WiMAX interface though their WiFi interface.  [[BR]]
    164 6)  Management of the WiMAX testbed.  Since the WiMAX testbed will be used by several researchers in the University we will develop a managerial tool in order to give to researchers remote access and to make available particular parameters for defining and running experiments,  collecting the results and monitoring the whole process.
    165 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]]
