<title><![CDATA[Brain-Computer Interface: Next Generation Thought Controlled Distributed Video Game Development Platform]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188749]]></link>
<description><![CDATA[This paper presents a system that uses the human ability to control a video game on a mobile device using ElectroEncephaloGraphic (EEG) Mu rhythms. The signals were obtained using a specially designed electrode cap and equipment, and sent through a Bluetooth connection to a PC that processes it in real time. The signal was then mapped onto two control signals and sent through wireless connection to a mobile gaming device BreakOut. The paper has also investigated the human's ability to play the video game by manipulating neuronal motor cortex activity in the presence of a visual feedback environment. The participants played the video game by using their thoughts only with up to 80% accuracy over controlling the target.]]></description>

<title><![CDATA[Using Co-Presence Communities to Enhance Social Recommendation]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188737]]></link>
<description><![CDATA[This paper proposes a social recommendation algorithm for use in a research social network environment. The social recommendation algorithm proposed combines the concepts of a relationship ontology and item-based Collaborative Filtering (CF). While the network setup in social networking sites can accurately reflect the social landscape of its users, it is much harder to detect the importance or strength of any one link. The paper therefore proposes an extension to the recommendation algorithm which makes use of the idea of co-presence communities to increase the relevance of the recommendations. A co-presence community can be detected from with data collected from Bluetooth-enabled mobiles. Detection of a co-presence community can help determine the nature and importance of the social links between participating members.]]></description>

<title><![CDATA[Wi-Fi and Bluetooth: The Path From Carter and Reagan-Era Faith in Deregulation to Widespread Products Impacting Our World]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188725]]></link>
<description><![CDATA[The rules adopted in Docket 81-413 had a much greater impact than any of its advocates could ever have imagined at the time. They enabled the development of Wi-Fi, Bluetooth, the majority of cordless phones now sold in the US, and myriad other lesser-known niche products. In doing so they created employment and growth for the communications electronics industry but the nature of the unforeseen products produced also changed the daily world and created further economic growth through improving efficiency of the society. Unlicensed systems also became a serious player in the communications infrastructure, although serious disagreements continue as what their role should be in the long-term. Without the success of the ISM bands, this discussion would not even be on the table.]]></description>

<title><![CDATA[A Simple Adaptive MAC Scheduling Scheme for Bluetooth Scatternet]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188721]]></link>
<description><![CDATA[A simple adaptive MAC scheduling algorithm, called Gateway Oriented Scatternet Scheduling (GOSS), is proposed for data exchange in a Bluetooth scatternet. Unlike the existing scheme MDRP (Maximum Distance Rendezvous Point) that has a global superframe schedule shared by all gateways, the schedule used by each gateway is individually determined. Equal partition of the superframe schedule at a gateway to each connected piconet can thus be guaranteed, which enables a more robust performance than MDRP. In addition, GOSS allows a variable sized superframe at each gateway. To maximize its performance, the frame size can be dynamically adjusted according to the scatternet topology and traffic load in every predefined adaptation interval. Simulation results show that even a static GOSS prevails over MDRP.]]></description>

<title><![CDATA[Security Threats and Countermeasures in Bluetooth-Enabled Systems]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188715]]></link>
<description><![CDATA[Bluetooth is a technology for short range wireless data and realtime two-way voice transfer providing data rates up to 3 Mb/s. It can be used to connect almost any device to another device. Bluetooth-enabled devices, such as mobile phones, headsets, PCs, laptops, printers, mice, and keyboards, are widely used all over the world. Already in 2006, the one billionth Bluetooth device was shipped, and the volume is expected to increase rapidly in the near future. The target volume for 2010 is as high as two billion Bluetooth devices. Therefore, it is very important to keep Bluetooth security issues up-to-date. A s an interconnection technology, Bluetooth has to address all traditional security problems, well known from distributed networks.]]></description>

<title><![CDATA[A Compact Loop Type Antenna for Bluetooth, S-DMB, Wibro, WiMax, and WLAN Applications]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188713]]></link>
<description><![CDATA[As modern mobile communication systems have developed rapidly, the antenna, which can cover multiband and have broadband, is needed for mobile handsets. In addition, for next-generation mobile handsets, the antenna has to be compact, lower profile, light, and easy to be embedded because the size of the antenna often has a great influence on the whole size of wireless systems. There is generally the tradeoff between the size and performance of antenna because the characteristics of the antenna are closely concerned with its size. In the case of a planar inverted-F antenna, which is attractive to apply mobile handsets, the height of antennas is the critical factor for obtaining good performances.]]></description>

<title><![CDATA[Bluetooth-Enabled In-Home Patient Monitoring System: Early Detection of Alzheimer's Disease]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188707]]></link>
<description><![CDATA[As the baby boom generation is aging, more and more people are diagnosed with Alzheimer's disease, early detection of which is shown to be vital and necessary for better medical treatments and prolonging life expectancies. This paper proposes a Bluetooth-enabled in-home patient monitoring system, facilitating early detection of Alzheimer's disease. The paper takes advantage of short-range Bluetooth communications for in-home patient location tracking, and the location information can then be recorded in a local database. With the knowledge of the movement pattern of a patient, a medical practitioner is more likely to be able to determine whether a target patient is developing Alzheimer's disease.]]></description>

<title><![CDATA[Carrier-Sense ARQ: Squeezing Out Bluetooth Performance While Preserving Standard Compliancy]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188701]]></link>
<description><![CDATA[This paper proposes a simple and standard compliant retransmission mechanism, called Carrier - Sense Automatic Repeat reQuest (CS - ARQ), which aims at improving system performance, both in terms of throughput and energy efficiency, by avoiding useless data packet retransmissions. More specifically, in case of missed acknowledgment (ACK), the source makes use of its carrier-sensing capabilities to decide whether retransmitting the data packet or soliciting the ACK retransmission from the destination. The scheme is modeled by means of a two - state Markov Chain that permits to determine closed-form expressions for the throughput and energy efficiency figures. The analysis reveals that the CS - ARQ mechanism is actually capable of significantly enhancing the system performance, in particular in some critical scenarios, while preserving standard compliancy.]]></description>

<title><![CDATA[P2P Content Distribution to Mobile Bluetooth Users]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188697]]></link>
<description><![CDATA[Using handheld devices such as cellular phones and smart phones for personal entertainment has become commonplace in today's lifestyle. Virtually all of these devices are equipped with Bluetooth technology that can be used to distribute entertainment contents such as music and movie clips. Mobile users can download content from the opportunistically available infrastructure (e.g., Digital Billboards) as well as direct Peer-to-Peer (P2P) collaboration which significantly increases content availability/coverage. P2P content distribution protocol design is heavily influenced by the characteristics of Bluetooth, which is the main departure from Internet-based content distribution. However, little has been done to understand the performance of overall Bluetooth operations, ranging from peer discovery to data downloading, in dynamic environments with mobility, interference, and different Bluetooth versions/chipsets.]]></description>

<title><![CDATA[Performance Evaluation and Prediction of a Bluetooth Based Real-Time Sensor Actuator System in Harsh Industrial Environments]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188693]]></link>
<description><![CDATA[This paper deals with a performance evaluation of a Bluetooth based industrial real-time sensor actuator interface for stationary and mobile applications. The investigations were carried out in harsh industrial environments in the presence of parasitic machine emissions, intentional and unintentional interferers. The air paths were obstructed by moving machine parts and daily work traffic. As a result one can conclude, that wireless automation systems based on Bluetooth technology are extremely reliable due to their inherent system features like adaptive frequency hopping at high operating frequencies, error detection and correction. Neither parasitic machine emissions nor other radio systems or transceiver movements can impair the transmission, as long as distances are below 30 m.]]></description>

<title><![CDATA[Performance Evaluation of Bluetooth in a High Voltage Environment]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188691]]></link>
<description><![CDATA[The paper provides some experimental results of Bluetooth system performance in presence of some impulses in the High Voltage (HV) Laboratory at the Dresden University of Technology. The performance is evaluated by the measured BER of an established link between two Bluetooth modules. An impulse voltage generator creates a homogeneous electric field at voltages from 200 kV up to 500 kV. Some experiments has shown the Bluetooth link is extremely influenced by the high voltage impulses in the range above 450 kV that is equivalent to a lightning appearing in the nature. The examined BER has increased due to malfunction of the receiver and the raised noise level in that environment.]]></description>

<title><![CDATA[Autonomous Proximity Awareness of Bluetooth Devices]]></title>
<link><![CDATA[http://whitepapers.zdnet.com/abstract.aspx?docid=1188689]]></link>
<description><![CDATA[This paper focuses on designing autonomous device discovery algorithms for Bluetooth networks. The paper first extends the conventional asymmetric Bluetooth link model to three point-to-point symmetric link models. Their performances are compared analytically. To achieve proximity awareness among a group of Bluetooth devices, three control information exchanging methods are also proposed. Combining with the three link models, this gives 9 possible variants of autonomous device discovery algorithm. A comprehensive comparative study based on these 9 variants is then carried out using Bluehoc simulator.]]></description>
