A Mechanism for Quick Bluetooth Device Discovery∗
نویسندگان
چکیده
The device discovery time of Bluetooth is prohibitively long. This may significantly impact many mobile applications. In this work, we start by analyzing the frequency matching of Bluetooth, the major component of delay in its device discovery, for both versions V1.2 and V1.1 specifications. We then propose a new scheme called Dual Inquiry Scan to reduce the delay. The result is a reduction of average frequency matching from 22.98 seconds to 20.63 seconds in typical cases. If a master continuously sends ID packets, the delay can be further reduced from 1.075 seconds to 0.005 seconds.

متن کاملCarrier Sensing Scheme for Device Discovery in Bluetooth Low Energy Networks
Many researchers give attention to Bluetooth Low Energy (BLE) because it has solutions for short range communications. However, there still are many challenging issues which must be resolved before applying to the environment. Therefore, this paper propose an enhanced discovery mechanism for BLE device in order to avoid collisions during advertisement period. We adopt carrier sensing to BLE dev...
متن کاملEnhancing the Bluetooth Service Discovery Protocol
Bluetooth Service Discovery Protocol (SDP) enables a client application on a device to discover information about services on other Bluetooth devices. Every service is represented by a profile, identified by a 128-bit Universally Unique Identifier (UUID). A match occurs on a peer device if and only if at least one UUID specified by the client is contained in one or more of its service records. ...

Bluetooth Low Energy (BLE) is a short-range wireless communication technology aiming at low-cost and low-power communication. The performance evaluation of classical Bluetooth device discovery have been intensively studied using analytical modeling and simulative methods, but these techniques are not applicable to BLE, since BLE has a fundamental change in the design of the discovery mechanism,...
متن کاملThe Impact of Cooperative Learning and Mobile Learning through Bluetooth Device on Vocabulary Learning of Iranian EFL Learners
Cooperative learning has been found to affect different aspects of language learning by many researchers (e.g., Kagan, 1995; Kagan, 1999; Kessler, 1992; McGroarty, 1993). Likewise, mobile assisted language learning (MALL) has revealed significant impacts on the improvement of different language skills and components (e.g., Comas-Quinn et al. 2009; Divitini & Chabert, 2009; Motallebzadeh & Ganja...
