EFFICIENT NETWORK FLOODING AND TIME SYNCHRONIZATION WITH GLOSSY* ISEP | CISTER Auditorium 11 FEV 2014 | 11:00
In this talk, we will review Glossy, a novel flooding architecture for wireless sensor networks. Glossy performs fast network flooding by making concurrent transmissions of the same packet interfere constructively, allowing a receiver to decode the packet even in the absence of capture effects. Glossy also has the added benefit of achieving implicit time synchronization. The paper includes an extensive evaluation showing that Glossy floods packets within a few milliseconds, and time synchronization with an average error below one microsecond. In most cases, a node receives the flooding packet with a probability higher than 99.99%. Moreover, Glossy´s performance exhibits no noticeable dependency on network node density.
INVITED SPEAKER: NUNO PEREIRA BSc in Computer Engineering from the School of Engineering – Polytechnic of Porto (2002), MSc and PhD from the University of Minho (2005 and 2010). He is a researcher at CISTER, a top-ranked research unit of the Portuguese research system since 2001. He started his research work dedicated to traffic scheduling combining multimedia and industrial communication protocols, and also analyzed the timing behavior of several industrial communication protocols, having developed analysis techniques for them. More recently, Nuno developed novel medium access control protocols for wireless networks and explored efficient ways to obtain aggregated quantities in large scale, dense wireless networks. His research was published in more than 30 technical papers in peer reviewed scientific venues.
