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

Modeling interference in bluetooth piconets

(ICEEE). 1st International Conference on Electrical and Electronics Engineering, 2004., 2005
In this work, we model the interference in Bluetooth asynchronous piconets by obtaining the analytic and the simulated cumuhtive distribution function (CDF) and the probability density function (PDF) of the interference received by a Bluetooth device of a reference piconet and produced by asynchronous piconets which are present in the same region.

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).

Time-synchronised multi-piconet Bluetooth environments

IEE Proceedings - Communications, 2006
Multiple Bluetooth piconets operating in the globally available 2.4 GHz industrial, scientific and medical (ISM) band are likely to co-exist in a physical environment, supporting applications such as wireless earphones, keyboards etc. An independently operating Bluetooth piconet will inevitably encounter the interference from collocated piconets, which

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.

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.

New bluetooth inter-piconet schedule with a slave-to-slave piconet formation

5th European Personal Mobile Communications Conference 2003, 2003
The 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 ...

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.
