Analytical Investigation on the Coexistence of Bluetooth Piconets
IEEE Communications Letters, 2004In this letter, we address the issue of Bluetooth (BT) piconets coexistence by analytically deriving a lower bound on the aggregated throughput offered by BT piconets deployed in the same region and by evaluating the optimal number of piconets as a function of the region dimension.

An efficient algorithm for scheduling in bluetooth piconets and scatternets
Wireless Networks, 2009Bluetooth is a short-range radio technology operating in the unlicensed industrial-scientific-medical (ISM) band at 2.45 GHz. A piconet is basically a collection of slaves controlled by a master. A scatternet, on the other hand, is established by linking several piconets together in an ad hoc fashion to yield a global wireless ad hoc network.

Basic relationship on capacity of bluetooth piconets
2007 International Symposium on Intelligent Signal Processing and Communication Systems, 2007This paper analyzes the capacity of medium access in a Bluetooth system. A random model of data transmission has been developed, establishing the relationship between data rate and transmission success rate (or data loss rate) for the first time, i.e., in a piconet, too large data rate will surely bring data loss for any scheduling.

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.

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

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.

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.
