Bluetooth communication reliability of mobile vehicles

Bluetooth technology is a short-ranged wireless communication technology which is open, low-cost and a good replacement of the cable. It is now more and more wildly used in computer and its accessories, mobile phones. With Bluetooth sensors development, this kind of communication is implied as wireless data acquisition of control systems, whether the data can be transferred correctly and timely directly influence the control performance of the system. The data reliability has been defined as the possibility of the receiver successfully receives the packet which is sent by the sender in certain conditions. Three data protection methods are defined in Bluetooth transmission (1/3FEC (Forward Error Correcting), 2/3FEC and ARQ scheme)^[1]. This paper analyzed the effect of these three schemes in the two typical working method of Bluetooth, and the reliability of the data transmission is calculated.
