THE APPLICATION OF BLUETOOTH IN THE SMART-ITS SENSOR NETWORK

Abstract

Using reduced power and likely without the support of a central system, potential ubiquitous computing devices would need to connect with other smart devices in an ad hoc manner. However, in the area of ubiquitous computing, no single communication system has so far developed itself: many existing wireless communication systems appear to lack robustness, use too much electricity, or need networks to be a viable contender. We have incorporated a Bluetooth module into the first prototype of a distributed sensor network node, built within the European Smart-Its research project, to test the suitability of the latest and promising Bluetooth protocol for certain connectivity requirements. Although Bluetooth allows stable and easy ad hoc communication, preliminary studies indicate that better support for symmetric communication and slave-to-slave communication may benefit from the Bluetooth standard.
