The recent industry standard Bluetooth promises low cost replacement of communication cabling with moderate symbol-rate, short-range wireless links. The same specification also addresses the establishment of point-to-multipoint piconets and the interconnection of several of these piconets into scatternets, enabling Bluetooth to be used as a technology for realizing personal area networks. Estab...

In recent years, wireless ad hoc networks have been a growing area of research. The advent of Bluetooth wireless technology makes it possible to transmit real-time video/audio in mobile and pervasive environments. In comparison with the other wireless standard such as 802.11x and IrDA, Bluetooth is more cost-efficient and power-efficient , making it ideal for small, light mobile devices. Howeve...

WiFi and Bluetooth are two most commonly used short range wireless communication technologies. Recent years, with increasing number of WiFi and Bluetooth mobile terminals, tags, and other devices, a demand for integration and coexistence of these two technologies including their positioning function is booming. In this paper, we firstly investigate the interferences between WiFi and Bluetooth s...

Gaming applications in ubiquitous computing environments will be in need of wireless communication facilities. In this paper, we outline advantages and drawbacks of Bluetooth. As a first step, we examine general issues of gaming applications in ubiquitous computing environments. Afterwards, we show how Bluetooth can cope with these issues. Furthermore, we describe two prototype applications: a ...

Bluetooth technology (BT) and the inherent security vulnerabilities it introduces into business domains are often overlooked when security policies are developed. However, the International Data Corporation (IDC) projected that global Bluetooth short-wave wire semiconductor revenue will triple from $1.7 billion in 2007, to $3.3 billion in 2012 (Reidy, 2008). After a brief history of Bluetooth t...

Bluetooth scatternets are formed by interconnecting Bluetooth piconets in an ad-hoc fashion and consists typically of the handheld electronic devices from one or more user(s). Thus, scatternets may be used to form and interconnect adhoc Bluetooth personal area networks (PANs). The inter-piconet Bluetooth units, i.e. the gateways interconnecting the piconets in a scatternet, need to time divisio...

Smartphone vendors have been increasingly integrating Bluetooth technology into their devices to increase accessible and convenience for users. As the current inclination of integrating PDA and telephony increase, the likelihood of sensitive information being stored on such a device is also increased. Potential Bluetooth vulnerabilities could provide alternative means to compromise Bluetooth-en...

This thesis presents BlueRelay, a novel protocol that extends the Bluetooth specification to support multi-hop wireless communication. Bluetooth is a wireless communication protocol originally designed for point-to-point communication within a small network called a piconet, where a master has centralized coordination over slave devices. The purpose of BlueRelay is to enable inter-piconet commu...

0974-9756/CIIT–IJ-1777/07/$20/$100 © 2011 CiiT Published by the Coimbatore Institute of Information Technology Abstract---Bluetooth is a low-cost, low-power wireless technology initially designed for cable replacement. With the new mobile lifestyle based on battery powered devices, Bluetooth came short in satisfying the needs of the high-rate applications due to its’ limited data rate. Introduc...

− Bluetooth is a promising wireless technology to form the personal area network and is being applied in versatile areas including both IP and non-IP protocol services. The current transport service can only provides best-effort for all master-slave connections. It is a challenge for providing quality of service (QoS) in the Bluetooth piconet because of the feature of master driven Time Divisio...
