Distributed Construction and Maintenance of Bandwidth-Efficient Bluetooth Scatternets [PDF]
, 2005 Bluetooth networks can be constructed as piconets or scatternets depending on the number of nodes in the network. Although piconet construction is a well-defined process specified in Bluetooth standards, scatternet construction policies and algorithms ...

Sensor Protocol for Roaming Bluetooth Multiagent Systems
International Journal of Distributed Sensor Networks, 2013 Bluetooth is a low-cost, short-range wireless technology capable of providing many communication functionalities. However, Bluetooth does not support any sensor protocol which is related to a roaming and in which handoff occurs dynamically when a ...

A new insight into Bluetooth piconets coexistence
Wireless Communications and Mobile Computing, 2008 AbstractThis paper discusses Bluetooth piconets coexistence. We use an approach which is totally different from those used traditionally with Bluetooth (probabilistic collision models). We show how it is possible to obtain an interference‐free Bluetooth environment in some conditions, for certain kinds of Bluetooth devices, using the properties of the ...

Performance comparison of overlaid bluetooth piconets (OBP) and bluetooth scatternet
IEEE Wireless Communications and Networking Conference, 2006. WCNC 2006., 2006 In a large scale Bluetooth network, scatternet is 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. We propose overlaid Bluetooth piconets (OBP) to interconnect

Introducing Service Differentiation in a Bluetooth Piconet [PDF]
, 2004 In this paper, we focus on the Bluetooth wireless network, analyzing its ability to support Quality of Service (QoS) requirements defined by the application. We focus on two QoS parameters : (i) an application constraint denoting the importance degree of a message, and (ii) an end-to-end delivery deadline.

Wireless Communications and Mobile Computing, Volume 2018, Issue 1, 2018., 2018 In the application of a body area network in medical healthcare, the process of receiving, archiving, and analyzing multibiosignals simultaneously from different devices for each body is very important. For example, to diagnose sleep apnea symptoms, a patient must sleep with dozens of devices, including electroencephalography (EEG), electrocardiogram ...
