Data generation rates of sensors are rapidly increasing, reaching a limit such that storage expansion cannot keep up with the data growth. We propose a new big data archiving scheme that handles the huge volume of sensor data with an optimized lossy coding. Our scheme leverages spatial and temporal correlations inherent in typical sensor data. The spatio-temporal correlations, observed in quality...
Dedicated short-range communication (DSRC) plays an important role in sensor networking for intelligent transportation system applications. How to achieve a higher hardware efficiency becomes an attractive issue to design each critical building bock in sensor node. DSRC standards usually adopt either FM0 code or Manchester code as a coding technique to enhance signal reliability. In this paper, a...
