The ever greater advances in technology enable a multitude of pervasive computing applications:
Smart homes like the TUD's surPLUShome, for instance, enable the injection of energy into the power grid by intelligently managing the energy generated and consumed.
In logistics, the status of millions of items, containers or transporters is monitored in near real time to enable timely and well informed business decisions.
In disaster scenarios, emergency responders can better coordinate their actions through the support from autonomous robots and the additional information from infrastructure(less) wireless sensors.
Human activities can be monitored, e.g. to enable better tracking of fitness exercises, but also to follow the health course of the elderly, thereby reducing attention costs.
To enable the deployment of these applications, we at DVS work on different aspects of the distributed systems involved and their associated research challenges. While centered on the middleware and its subsystems, we look at the entire stack, spanning from the bottom-end, low-power tiny sensor node platforms, to the top-level delivery of meaningful services and data.
