Development of Communication Interfaces between the Base-Station and the User Device for Wireless Automotive Sensor Network System

This paper designs and develops the communication interface between base-station and user device (e.g., smart-phone, smart-pad) which are components of the wireless automotive sensor network system. The wireless automotive sensor network system provides a variety of driver assistance information for drivers by using wireless sensor network technologies. The communication interfaces are needed to provide driver assistance information through the user device. This communication interfaces have a basic message format and consists of the command, state, ACK (acknowledgment), and data message formats according to message type. The base-station transmits a variety of sensor and vehicle information by the command message transmitted from the user device. Drivers are provided with various driver assistance services (e.g., tire pressure monitoring, parking assistance, air conditioner service) by using these communication interfaces. The communication interfaces are applied to wireless parking assistance system to verify usefulness and effectiveness of these communication interfaces.
