Multimedia support over bluetooth Piconets

Proceedings of the first workshop on Wireless mobile internet, 2001
In this paper we explore the ability to support multimedia traffic in indoor, wireless ad hoc PANs (Personal Area Networks) using the Bluetooth technology. We first define the representative ad hoc networking applications such as wireless access to the Internet, document distribution, videoconferencing, webcasting, interaction with sensors and ...

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.

On Bluetooth piconet traffic performance

The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003
The performance of a single Bluetooth piconet is analyzed using the theory of M/G/1 queues with vacations. Analytical results for probability distributions of packet access time and service cycle time are derived. Two scheduling policies, limited and exhaustive service, are considered.

Impact of polling on bluetooth piconet performance

IEEE Communications Magazine, 2011
Bluetooth has become a ubiquitous technology present in almost every electronic device. A question often asked by manufacturers and final users is whether it can be used for uses other than the ones for which it was designed; in particular, for improved multimedia traffic support, with the fewest modifications in the implementation of the protocol ...

Performance of Bluetooth piconets with finite buffers

First International Conference on Quality of Service in Heterogeneous Wired/Wireless Networks, 2004
We analyze the performance of E-limited scheduling in Bluetooth piconets under bursty traffic finite buffer case. We model the joint probability distributions of uplink and downlink queues using M/sup [x]//G/1/K model and derive buffer blocking probabilities at slaves and at the master. Wd also derive access delays at slaves' buffers.

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.

Video streaming over overlaid bluetooth piconets (OBP)

Proceedings of the 1st international workshop on Wireless network testbeds, experimental evaluation & characterization, 2006
In 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.

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

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.

Throughput evaluation for a bluetooth piconet with link adaptation

14th IEEE Proceedings on Personal, Indoor and Mobile Radio Communications, 2003. PIMRC 2003., 2004
In this paper a link adaptation (LA) strategy to be implemented in a Bluetooth piconet is investigated: the performance level that can be achieved is derived and the comparison with the case of no LA is performed. Suitable definitions of the performance figures are given and starting from the knowledge of the physical level performance obtained via ...
