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.

Impact of polling on bluetooth piconet performance
IEEE Communications Magazine, 2011Bluetooth 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, 2004We 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.

Multimedia support over bluetooth Piconets
Proceedings of the first workshop on Wireless mobile internet, 2001In 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 ...

Performance Evaluation in Bluetooth Dense Piconet Areas
IEEE Transactions on Wireless Communications, 2004Bluetooth is a low-cost, short-range wireless technology capable of providing many communication functionalities, ranging from wire replacement to simple personal area networking. In Bluetooth local networking applications, a critical issue still under study is the evaluation of the network performance when multiple piconets are simultaneously active ...

Throughput evaluation for a bluetooth piconet with link adaptation
14th IEEE Proceedings on Personal, Indoor and Mobile Radio Communications, 2003. PIMRC 2003., 2004In 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 ...

The study for the optimal routing of Bluetooth Piconet
Proceedings of the 2nd International Conference on Interaction Sciences: Information Technology, Culture and Human, 2009the best route is to upgrade the network of efficient and effective way to transmit; the NS2 network simulator can effectively simulate a variety of different environments. This paper using the NS2 simulation of Bluetooth System, the formation of two kinds of tree and ring a Bluetooth Piconet. In the transmission data to improve the packet transmission

Load and QoS-adaptive scheduling in Bluetooth piconets
37th Annual Hawaii International Conference on System Sciences, 2004. Proceedings of the, 2004A 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., 2005In 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, 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 ...
