— In this paper, we propose a theoretical framework for the analysis of the impact of ultra–wideband (UWB) interference on systems that use the popular combination of bit– in...
By integrating wireless wide area networks (WWANs) and wireless local area networks (WLANs), mobile hotspot technologies enable seamless Internet multimedia services to users on-bo...
Existing wireless networks usually provide multiple data transmission rates. This paper presents a simulation study on the performance of multiple-rate mobile ad hoc networks (MAN...
The objective of this paper is to present the recent development of the ring sensor to monitor a patient 24 hours a day for a tele-nursing system. The ring sensor is worn by the p...
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 ...
