Networked Embedded Systems

Relative Localization with GPS

In many mobile wireless applications such as the automated driving of cars, formation flying of unmanned air vehicles, and source localization or target tracking with wireless sensor networks, it is more important to know the precise relative locations of nodes than their absolute coordinates. GPS, the most ubiquitous localization system available, generally provides only absolute coordinates. Furthermore, low-cost receivers can exhibit tens of meters of error or worse in challenging RF environments.

Vodafone Wireless Innovation

Recently ISIS teamed up with the Clinton Climate Initiative and submitted an idea of a mobile green house gas and air pollution monitoring system to the Vodafone Foundation Wireless Innovation Program. The proposal made it to the final, where Ákos Lédeczi presented it to a panel of judges. Unfortunately, it was not picked up as one of the three winners.

ISIS in the News

 The Mobile Air Pollution Monitoring Network developed at ISIS was recently featured at the ScienceNews website. The system makes it possible to obtain a detailed picture of the air quality in a city. The project was sponsored by Microsoft Research.
