Seminars at the Faculty of Informatics

The Faculty of Informatics is pleased to announce a seminar given by Jacob Chakareski

DATE: Thursday, June 16th, 2011
PLACE: USI Università della Svizzera italiana, room SI-008, Black building (Via G. Buffi 13)
TIME: 10.30

ABSTRACT:
The Internet has evolved from the mere academic curiosity it represented at its inception, interconnecting just a few universities on the West Coast, to the present user and content centric behemoth network delivering a wide array of services to millions of people across the globe. The ongoing technological advances that are the driving force behind the Internet innovation today promote a remarkable convergence of people, devices, and content that in turn exhibits a plethora of contextual information. The goal of my research is to take advantage of this convergence to optimize information systems and design novel services thereby opening the road to the next generation context-driven data networking. The talk will overview three related investigations in which I have used contextual information to provide enhanced performance and cost efficient operation. Specifically, I will show how node and link weighted maximum spanning trees can be constructed for broadcast of user generated content in online communities. I will also show how peer-to-peer systems can be optimized in terms of topology construction and data packet scheduling for the goal of live media streaming. Finally, in the context of IPTV I will overview our optimization framework for allocating bandwidth and forward error correction resources across the client population such that substantial performance advances are achieved over conventional techniques. At the end of the talk, I will summarize my recent research on multiple view imaging in the context of immersive multimedia environments.
