An Analytical Study of the Delay in Bluetooth Networks Using the Personal Area Network Profile

Bluetooth is the most employed technology to develop wireless personal area networks. This letter studies the performance of Bluetooth transmissions that make use of the PAN (personal area network) profile. In particular, the study offers an analytical model that defines the optimal bound for the end-to-end data delay. The proposed 'delay budget' takes into account the overhead and segmentation provoked by the protocols involved in the transmission of user data. The model is empirically validated by comparing its results with those obtained through the measurements of actual Bluetooth connections.
