Modeling Bluetooth piconet performance
IEEE Communications Letters, 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 are modeled and compared: exhaustive service was found to perform better, but limited service does not incur the ...

Congestion control of bluetooth radio system by piconet restructuring
Journal of Network and Computer Applications, 2008 Bluetooth is a low-cost and short-range wireless communication technology. Two or more bluetooth devices connected form a piconet and two or more piconets connected form a scatternet through relay devices. Without the consideration of traffic flows, a scatternet may operate with serious congestion problem.

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

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 ...

Bluetooth Throughput Improvement Using a Slave to Slave Piconet Formation
, 2003 This paper addresses issues for the establishment of multihop ad-hoc networks based on Scatternet formation using bluetooth. We describe a new approach of inter-piconet communication. Differing from existing protocols, the design allows the slave to establish contact with other slaves present in the piconet without passing through the master.

On Bluetooth piconet traffic performance
The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003The 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.

Admission Control in Bluetooth Piconets
IEEE Transactions on Vehicular Technology, 2004We analyze the performance of E-limited scheduling in Bluetooth piconets under bursty traffic for infinite and finite buffer cases. We show that E-limited service outperforms exhaustive service in terms of end-to-end delay and that the delays may be minimized through the proper choice of a single variable parameter: the number of packets to be ...

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.
