Abstract. Wireless sensor network protocols and applications, including those used for localization, topology control, link scheduling, and link quality estimation, make extensive ...
The home environment becomes ready to host distributed devices dynamically adapting to service availability and reacting to user location and user activity. Sensors, high definiti...
We describe and evaluate a distributed architecture for the online recognition of user activity sequences. In a lower layer, simple heterogeneous atomic activities were recognised ...
