Biographical Sketch:

Goce Trajcevski obtained his BS from the University of Sts. Kiril and Metodij in Skopje, and his MS and Phd from the department of Computer Science at the University of Illinois at Chicago, under the mentorship of Ouri Wolfson. He has published 40 papers in refereed conferences, workshops and journals, has been on program committees of numerous conferences and frequently served as journal reviewer, in addition to being Associate Editor for ACM-DiSC. He has received the Best Paper Award at the CoopIS conference, and was US Geological Survey scholar. Currently, he is Assistant Chairman of the Department of Electrical Engineering and Computer Science at Northwestern University. His main research interests are centered around mobile data management, reactive behavior, and information management in wireless sensor networks.

Abstract:

Moving Objects Databases have become an enabling technology for a variety of applications that require some type of Location Based Services: military, environmental, medical/assisted living, traffic management - to name but a few. However, the management of the large amounts of mobile objects, in addition to the efficient processing of some typical queries (e.g., range, nearest-neighbor), may require other kinds of context-awareness. In many applications settings, given the current state and the history of the spatio-temporal evolution of the mobile entities, certain activities may need to be undertaken - e.g., increasing the quality of tracking; re-routing of mobile resources, etc. In such cases, in addition to reacting to a particular event (primitive and/or composite) and (pending the condition) executing the corresponding action, the available resources may need to be reorganized and steered towards monitoring different events than the ones in the recent past. In this talk, we will present several application scenarios and demonstrate that they "converge" in the sense that in all of them it is essential to efficiently detect whether a particular type(s) of spatio-temporal predicate is satisfied. More importantly, the satisfaction of such predicate has subsequent implications on how the application requirements are monitored and managed. In addition to the processing algorithms, we will present a formalism for context-aware management of the reactive behavior with pro-active impacts in such mobile dynamic systems.
