Mitigation of Co-Channel Interference in Bluetooth Piconets

IEEE Transactions on Wireless Communications, 2012
In 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 new efficient scheduling algorithm in bluetooth piconet

IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005
Bluetooth 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).

Load and QoS-adaptive scheduling in Bluetooth piconets

37th Annual Hawaii International Conference on System Sciences, 2004. Proceedings of the, 2004
A novel polling scheme for intra-piconet scheduling in Bluetooth piconets, dubbed adaptive cycle-limited scheduling, is described. The scheme allocates the time to each slave according to its current traffic, whilst trying to limit the maximum piconet cycle time. This approach makes scheduling of mixed asynchronous and CBR traffic much easier than with

Piconet security in IEEE 802.15.3 WPAN

IEEE Wireless Communications and Networking Conference, 2005, 2005
IEEE 802.15.3 is designed for short-distance wireless connectivity within a wireless personal area network (WPAN). It has great significance for applications such as home networking. Security is one of the fundamental issues in IEEE 802.15.3 WPAN. Although several security mechanisms have been defined in the standard, there are many others open and ...

Analytical Investigation on the Coexistence of Bluetooth Piconets

IEEE Communications Letters, 2004
In 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.

Basic relationship on capacity of bluetooth piconets

2007 International Symposium on Intelligent Signal Processing and Communication Systems, 2007
This 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.

An Efficient and Optimized Bluetooth Scheduling Algorithm for Piconets

2007
Bluetooth is a short-range radio technology operating in the unlicensed industrial-scientific-medical (ISM) band at 2.45 GHz. A scatternet is established by linking several piconets together in ad hoc fashion to yield a global wireless ad hoc network.

An efficient algorithm for scheduling in bluetooth piconets and scatternets

Wireless Networks, 2009
Bluetooth 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.

Differentiated Priority Scheduling and Adaptive Segmentation for Bluetooth Piconets

Proceedings of the 39th Annual Hawaii International Conference on System Sciences (HICSS'06), 2006
Bluetooth 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. Bluetooth’s MAC is a polling based protocol, where a central Bluetooth unit (master) determines channel access to all other nodes (slaves) in the network ...

Mutual interference between independent bluetooth piconets

IEEE Transactions on Vehicular Technology, 2003
The 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.
