A Study on Scalable Bluetooth Piconet for Secure Ubiquitous
2005Due to the changes in the wireless information environment, there has been an increased demand for various types of information. Accordingly, many wireless communication technologies have been studied and developed. In particular, studies on ubiquitous close distance communications are well underway.

A Sniff Scheduling Policy for Power Saving in Bluetooth Piconet
11th International Conference on Parallel and Distributed Systems (ICPADS'05), 2005After deeply analyzing sniff mode which is a low power operation mode of Bluetooth, a learning function is used to approximate the distribution of the incoming traffic at a master-slave pair. Based the inter-arrival times of data packets obtained from the learning function, the mean of these inter-arrival times is the possible sniff interval; according

Differentiated Priority Scheduling and Adaptive Segmentation for Bluetooth Piconets
Proceedings of the 39th Annual Hawaii International Conference on System Sciences (HICSS'06), 2006Bluetooth is a wireless communication technology, aimed at supporting connectivity among close proximity mobile devices. Bluetooth enables the design of low-power, low-cost, and small-size radios. Bluetooths MAC is a polling based protocol, where a central Bluetooth unit (master) determines channel access to all other nodes (slaves) in the network ...

Performance of PHY and MAC layers of a bluetooth piconet in multi-bluetooth interference environment
IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005Operating in the 2.4 GHz unlicensed ISM band, a Bluetooth piconet inevitably encounters interference from other Bluetooth piconets. In the literature, the focus has been mainly on the analysis of the collision probability ( P/sub c/) of a Bluetooth packet.

Mutual interference between independent bluetooth piconets
IEEE Transactions on Vehicular Technology, 2003The Bluetooth wireless communication technology provides wireless solutions applicable for a number of communications needs. In addition, multiple independent piconets are possible and likely to occur within the same location, either intentionally or by chance.

Performance of a Bluetooth piconet in the presence of IEEE 802.11 WLANs
The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003Bluetooth is a digital wireless data transmission standard in the 2.4 GHz ISM band aimed at providing a short range wireless link between laptops, cellular phones and other devices. The IEEE 802.11 wireless local area networks (WLANs) also operate in this frequency band.

Video streaming over overlaid bluetooth piconets (OBP)
Proceedings of the 1st international workshop on Wireless network testbeds, experimental evaluation & characterization, 2006In a large scale Bluetooth network, scatternet has been regarded as the only interconnection method among piconets. But, most Bluetooth devices do not support scatternet connection. Moreover, in high mobility situations, scatternet is not useful because of frequent disconnections and reconnections.

WIRELESS EARPHONE FOR USE IN BLUETOOTH PICONETS
The Journal of the Acoustical Society of America, 2013An audio device includes a Bluetooth receiver, a Bluetooth transmitter, a speaker and a housing. The Bluetooth receiver is capable of wirelessly receiving signals in at least two audio channels. The Bluetooth transmitter is capable of wirelessly retransmitting at least a first one of the two audio channels.

Improving the performance of bluetooth piconets with synchronous and asynchronous traffic
GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004The Bluetooth specification allows both asynchronous (ACL) and synchronous (SCO) links to be present in a piconet. However, the performance of ACL traffic rapidly deteriorates when an SCO link is present. This paper investigates the possibility of replacing the Bluetooth SCO connection with a QoS-constrained asynchronous link that uses multi-slot ACL ...

An efficient link polling policy by pattern matching for Bluetooth piconets
36th Annual Hawaii International Conference on System Sciences, 2003. Proceedings of the, 2003Bluetooth has a master-slave configuration, called a piconet. Unspecified in the Bluetooth standard, the link polling policy adopted by a master may significantly influence the bandwidth utilization of a piconet. Several works have dedicated to this issue by A. Capone et al. (2001), I. Chakrabory et al. (2001), A. Das et al. (2001), M.
