Mitigation of Co-Channel Interference in Bluetooth Piconets
IEEE Transactions on Wireless Communications, 2012In this letter, we consider the mitigation of co-channel interference in Bluetooth piconets. Prior to sending packets, the proposed scheme checks whether the next channel for the frequency hopping (FH) is in use by other signals or not. Then, it periodically detects busy channels subject to WLAN interference based on the packet error rate and ...

A practical approach to multicasting in Bluetooth piconets
IEEE Wireless Communications and Networking Conference, 2006. WCNC 2006., 2006This work studies a special multicasting problem in Bluetooth networks supporting point-to-point connections and piconets. The reason for the topic choice relies in the fact that Bluetooth, a de-facto proximity communication technique widely available in smart phones today, supports piconets, but sending content to more than 7 nodes is cumbersome.

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.

A new efficient scheduling algorithm in bluetooth piconet
IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005Bluetooth is a system for providing short-range, small size, low-power and low-cost connectivity operating in the ISM (industrial scientific medicine) band at 2.4 GHz (http://www.bluetooth.com). Bluetooth has been seen as a promising candidate for ad-hoc wireless networking and wireless personal area networks (WPAN).

New Bluetooth inter-piconet schedule with a slave to slave piconet formation
5th European Personal Mobile Communications Conference 2003, 2003The growing use of information intensive consumer devices such as cell phones, personal digital assistants (PDAs), and laptop computers have called for a new networking paradigm for their interconnection. Up to 8 Bluetooth devices can form a centralized network, called a piconet, controlled by a master node, which allocates transmission slots to all ...

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 ...

Building a dark piconet upon Bluetooth interfaces of computers
MILCOM 2009 - 2009 IEEE Military Communications Conference, 2009In this paper we demonstrate an attack scenario in which Bluetooth enabled computers are remotely controlled by an attacker without any security software detecting the connection. We describe in detail the methods to deliver malware, evade detection, elevate permissions, and transport critical information out of the network via Bluetooth connections. A

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.

Packet Error Rate Distribution Between Random Bluetooth Piconet Pairs
Wireless Personal Communications, 2005The packet error rate between two piconets depends on the temporal alignment of their packets and the spectral alignment of the intervals from which the frequencies in their hop sequence are chosen. The relationship between two randomly paired piconets is one of over 828 billion possible relationships.

Innovation on Bluetooth intra-piconet scheduling algorithms
2014Intra-piconet scheduling is one of the factors that affect performance of Bluetooth networks. In this thesis, we present two new intra-piconet scheduling algorithms that offer better performance than the existing ones. In case Bluetooth is used to carry voice traffic using the SCO packet types proposed in the official standard, the performance of ...
