2. D. Goodman WICAT Wireless Internet Center for Advanced Technology A new National Science Foundation Industry/University Cooperative Research Center David Goodman, Director Faculty and students at Poly and Columbia Univerisity Departments of ECE and Computer Science

3. D. Goodman RESEARCH GOALS Prof. David Goodman oMake efficient use of scarce resources in wireless communications: oRadio bandwidth oBattery energy in portable devices

4. D. Goodman PROJECTS oMaximize throughput and battery life of cellular data transmission: oAdjust transmitter power oAdjust bit rate oSchedule transmissions to and from different terminals oMaximize battery life in wireless video transmissions oAdjust compression oAdjust transmitter power oWi-fi access points configured as Infostations efficiently manage information on campus and other local areas

5. D. Goodman APPROACH oIn a wireless system many terminals share the same transmission medium oEach one competes or interferes with the others oMathematics of game theory and microeconomics lead to optimum allocation of resources (power and bandwidth) oDevise algorithms and protocols that enable practical terminals to achieve optimum results
