A new insight into Bluetooth piconets coexistence

open access: yesWireless 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 ...

Wireless TDMA‐Based Body Area Network Platform Gathering Multibiosignals Synchronized with Patient’s Heartbeat

open access: yesWireless 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 ...

BGN: A Novel Scatternet Formation Algorithm for Bluetooth‐Based Sensor Networks

open access: yesMobile Information Systems, Volume 7, Issue 2, Page 93-106, 2011., 2011
To address the unreliability and inefficiency of the existing algorithms for Bluetooth scatternet formation, this paper proposes a new efficient algorithm, Bluetooth Growing Network (BGN) algorithm, which constructs Bluetooth scatternet by adding reserve links among its branch nodes so that the resulting scatternet can maintain a high degree of ...

Improving Sensing Accuracy in Cognitive PANs through Modulation of Sensing Probability

open access: yesMobile Information Systems, Volume 5, Issue 2, Page 177-193, 2009., 2009
Cognitive radio technology necessitates accurate and timely sensing of primary users′ activity on the chosen set of channels. The simplest selection procedure is a simple random choice of channels to be sensed, but the impact of sensing errors with respect to primary user activity or inactivity differs considerably. In order to improve sensing accuracy
