DESCRIPTION:Wireless Sensor Networks are spreading\, and in ma
 ny cases\, these systems are deployed in remote ar
 eas for environmental/wildlife monitoring purposes
 \, and involve tens or even hundreds of sensors. T
 hey are expected to work without much human interv
 ention\, and for as long as possible. So far\, the
  majority of these networks are not reusable or ad
 aptive\, in the sense that once the sensors are de
 ployed\, they cannot easily be reprogrammed unless
  someone collects them and connects them to a comp
 uter. This task is even more difficult (if not imp
 ossible) if the devices are attached to mobile ent
 ities or animals as these cannot easily be recolle
 cted. The current (few) solutions of the distribut
 ion of new code on a mobile sensor networks involv
 ed epidemic-like spreading of the code over the ne
 twork. In this talk I present a group-based code-d
 issemination protocol\, which takes advantage of t
 he dynamically built knowledge about the social re
 lationships between the nodes to efficiently distr
 ibute the code\; and a proposed system to selectiv
 ely update specific subsets of the network.\n\nBio
 : I received my BSc in Computer Science from the U
 niversity College London in 2007. I started a Phd 
 soon after graduation\, and transferred to Cambrid
 ge in 2008. I've been working on a routing protoco
 ls for mobile WSN.
