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

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 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).

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.

An efficient algorithm for scheduling in bluetooth piconets and scatternets
Wireless Networks, 2009Bluetooth 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.

Basic relationship on capacity of bluetooth piconets
2007 International Symposium on Intelligent Signal Processing and Communication Systems, 2007This 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.

A Sniff Scheduling Policy for Power Saving in Bluetooth Piconet
11th International Conference on Parallel and Distributed Systems (ICPADS'05), 2005After deeply analyzing sniff mode which is a low power operation mode of Bluetooth, a learning function is used to approximate the distribution of the incoming traffic at a master-slave pair. Based the inter-arrival times of data packets obtained from the learning function, the mean of these inter-arrival times is the possible sniff interval; according

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 ...

Performance of PHY and MAC layers of a bluetooth piconet in multi-bluetooth interference environment
IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005Operating in the 2.4 GHz unlicensed ISM band, a Bluetooth piconet inevitably encounters interference from other Bluetooth piconets. In the literature, the focus has been mainly on the analysis of the collision probability ( P/sub c/) of a Bluetooth packet.
