Enabling Cognitive Load‐Aware AR with Rateless Coding on a Wearable Network
Advances in Multimedia, Volume 2008, Issue 1, 2008., 2008 Augmented reality (AR) on a head‐mounted display is conveniently supported by a wearable wireless network. If, in addition, the AR display is moderated to take account of the cognitive load of the wearer, then additional biosensors form part of the network. In this paper, the impact of these additional traffic sources is assessed.

Fuzzy Logic Control of Adaptive ARQ for Video Distribution over a Bluetooth Wireless Link
Advances in Multimedia, Volume 2007, Issue 1, 2007., 2007 Bluetooth′s default automatic repeat request (ARQ) scheme is not suited to video distribution resulting in missed display and decoded deadlines. Adaptive ARQ with active discard of expired packets from the send buffer is an alternative approach. However, even with the addition of cross‐layer adaptation to picture‐type packet importance, ARQ is not ...

Bluetooth: Opening a Blue Sky for Healthcare
Mobile Information Systems, Volume 2, Issue 2-3, Page 151-167, 2006., 2006 Over the last few years, there has been a blossoming of developing mobile healthcare programs. Bluetooth technology, which has the advantages of being low‐power and inexpensive, whilst being able to transfer moderate amounts of data over a versatile, robust and secure radio link, has been widely applied in mobile healthcare as a replacement for cables.

Performance analysis of Bluetooth piconets with finite baseband buffers [PDF]
Wireless Communications and Mobile Computing, 2005 AbstractWe analyze the performance of Bluetooth piconets under bursty traffic and finite buffer sizes. We model the joint probability distributions of uplink and downlink queues using theM[x]/G/1/Kmodel with vacations and derive buffer blocking probabilities at slaves and at the master. The results, which are confirmed through simulations, provide some

Location Based Mobile Computing–A Tuplespace Perspective
Mobile Information Systems, Volume 2, Issue 2-3, Page 135-149, 2006., 2006 Location based or ”context aware” computing is becoming increasingly recognized as a vital part of a mobile computing environment. As a consequence, the need for location‐management middleware is widely recognized and actively researched. Location‐management is frequently offered to the application through a “location API” (e.g.

Achievable rate regions for Bluetooth piconets in fading channels [PDF]
2004 IEEE 59th Vehicular Technology Conference. VTC 2004-Spring (IEEE Cat. No.04CH37514), 2005 We investigate the stability of a Bluetooth piconet operating in fading (Rice, Rayleigh or Nakagami) channels. By taking into account many protocol details, such as modulation scheme and packet formats, we provide an analytical characterization of the achievable rate regions, which, for a network of N nodes, turns out to be the interior of a convex ...

STUDI DAN UJI COBA TEKNOLOGI BLUETOOTH SEBAGAI ALTERNATIF KOMUNIKASI DATA NIRKABEL
Jurnal Informatika, 2004 Bluetooth is a new emerging technology. This technology gives significant changes for electronic devices that we are using. If we look around, a keyboard is connected to a computer. So does a printer, a mouse, a monitor and so on.
