Position and orientation information of individual nodes in ad hoc networks is useful for both service and application implementation. Services that can be enabled by availability...
Due to the limited energy supplies of nodes in many applications like wireless sensor networks, energy efficiency is crucial for extending the lifetime of these networks. This pape...
As the number of wireless devices sharing the unlicensed 2.4 GHz ISM band increases, interference is becoming a problem of paramount importance. We experimentally investigate the e...
Networks of small devices, such as environmental sensors, introduce a number of new challenges for traditional protocols and approaches. In particular, the extreme resource constr...
We describe a practical vision of ubiquitous computing with tangible interfaces, that orbits around an individual and is mediated by his or her personal consumer electronic device...
