Optimized inquiry mechanisms for Bluetooth devices

In this paper, we propose a simple and practical scheme for optimization the inquiry process in Bluetooth standards in order to achieve fast, reliable and controlled responses. We show how the inquiry process is related to clock setting in Bluetooth devices and how clock optimization could be used to shorten the inquiry process time. Theoretical analysis and simulation results shows the efficiency of the proposed optimized scheme. We also develop a traffic transportation application, i.e. speed measurement, as an example of many applications where this scheme could benefit. Results show how the proposed optimized scheme outperforms in comparison with others.
