Models and methods for wireless, reconfigurable, ring topology free space optical networks
Dr. Steven Gabriel, Dr. Stu Milner and various graduate students (Yohan Shim, Ph.D. Candidate CEE; Jaime Llorca, Res. Asst., Center for Networking of Infrastructure sensors) and others have developed models and methods for wireless, reconfigurable, ring topology free space optical networks used in telecommunications. These methods which need to determine optimal new networks in near-real time, can be used for congestion minimization as well as for network reconfiguration after man-made or natural disasters such as hurricanes. The work has shown that traditional optimization approaches on realistic networks are too slow relative to the near-real time demands of reconfiguration. Consequently, heuristic approaches have been developed which produce high quality solutions in seconds. This work was funded by a grant from the National Science Foundation.
