Abstract
This paper proposes a data collection scheme for the two-tier vehicle sensor network, which is comprised of high-speed WLANs surrounded by the ubiquitous cellular network, aiming at improving the accuracy and speed of event detection out of bunch of sensor data. Each vehicle reports periodically summary data including its location, timestamp, and alarm data via the cellular network, while it sends whole set, entering the WLAN range. For event detection, the information server locates the vehicles whose data must be further investigated according to the legacy spatio-temporal query or the trajectory comparison method. The WLAN can give precedence to the vehicle which might have the important data by operating two different frequencies. We are currently refining this framework and planning to test in Jeju area.
This research was supported by the MKE, Korea, under the ITRC support program supervised by the NIPA. (NIPA-2010-(C1090-1011-0009)).
