This work presents a measurement-based dependability evaluation of the Bluetooth data communication channel, i.e., the Baseband layer. The main contribution is the definition of the Baseband's error/recovery model according to the Markov chains formalism. The model is derived by analyzing field data, which are collected via a commercial air sniffer deployed over real- world Bluetooth piconets. The model is parametric and actual values for its parameters are estimated by analyzing the field data. The paper also proposes the evaluation of dependability statistics (e.g., the error and failure times distributions, and the availability estimate), and the study of the failing behavior of the Bluetooth communication channel under Wi-Fi interferences.

Abstract
This work presents a measurement-based dependability evaluation of the Bluetooth data communication channel, i.e., the Baseband layer. The main contribution is the definition of the Baseband's error/recovery model according to the Markov chains formalism. The model is derived by analyzing field data, which are collected via a commercial air sniffer deployed over real- world Bluetooth piconets. The model is parametric and actual values for its parameters are estimated by analyzing the field data. The paper also proposes the evaluation of dependability statistics (e.g., the error and failure times distributions, and the availability estimate), and the study of the failing behavior of the Bluetooth communication channel under Wi-Fi interferences.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
