In this paper, we proposed an indirect-contact ECG measurement system for evaluating driver's fatigue level. The preliminary experiment results reveal that the heart rate variability could be used to estimate fatigue level.
The dynamical network topology is the source of most challenges in VANETs (Vehicle Ad hoc Networks). In urban area, however, it is feasible to meet the challenge by taking advantage of the heavy traffic. This paper proposes a location aware virtual infrastructure (LAVI) based on recognition memory. Combining the memory of past cooperation with the location information, the mobile nodes can construct...
