DESCRIPTION:Wireless Sensor Networks are spreading\, and in many cases\, t
 hese systems are deployed in remote areas for environmental/wildlife monit
 oring purposes\, and involve tens or even hundreds of sensors. They are ex
 pected to work without much human intervention\, and for as long as possib
 le. So far\, the majority of these networks are not reusable or adaptive\,
  in the sense that once the sensors are deployed\, they cannot easily be r
 eprogrammed unless someone collects them and connects them to a computer. 
 This task is even more difficult (if not impossible) if the devices are at
 tached to mobile entities or animals as these cannot easily be recollected
 . The current (few) solutions of the distribution of new code on a mobile 
 sensor networks involved epidemic-like spreading of the code over the netw
 ork. In this talk I present a group-based code-dissemination protocol\, wh
 ich takes advantage of the dynamically built knowledge about the social re
 lationships between the nodes to efficiently distribute the code\; and a p
 roposed system to selectively update specific subsets of the network.\n\nB
 io: I received my BSc in Computer Science from the University College Lond
 on in 2007. I started a Phd soon after graduation\, and transferred to Cam
 bridge in 2008. I've been working on a routing protocols for mobile WSN.
