A Self-healing Protocol Stack Architecture for Bluetooth® Wireless Technology

Bluetooth wireless technology has gained in importance in recent years and can now be found in a multitude of devices ranging from keyboards, mice, and printers to handhelds, laptops, and mobile phones, to name only a few. Despite a complex product qualification process, practical experience shows that there are still situations where two products fail to work together as intended. In this paper we evaluate possibilities to adopt self-healing techniques to increase robustness and present the contours of a new self-healing architecture for Bluetooth protocol stacks. While there is still research to do to narrow down the class of problems which can be tackled that way and to refine our approach, initial experiences with a Java prototype implementation look encouraging.
