Development of vehicular base-station for wireless parking assistance system

In this paper, we develop vehicular base-station for wireless parking assistance system. We introduce in-vehicle wireless sensor network system which can provide the convenience/safety-related services by applying wireless sensor network technology. We develop wireless parking assistance system to verify usefulness and effectiveness of the in-vehicle wireless sensor network system. The wireless parking assistance system greatly consists of vehicular base-station and vehicular wireless sensor nodes. We present the vehicular base-station which is sub-system of wireless parking assistance system in this paper. The vehicular base-station carries out roles which process ECU information obtained from OBD (On-Board Diagnostics) module and sensor information received from wireless ultrasonic sensor nodes.
