Bluetooth is the term used to describe the protocol of short-range, and frequency hopping radio link between devices. Bluetooth enables users to connect wirelessly to a wide range of computing and communication devices easily and it provides opportunities for rapid ad hoc connections. In this type of networks, security is one of the main issues. Bluetooth link-level security provides authentica...

Network jammers can uncover the reliability of the wireless networks, where the position of the jammer node permit the network to cope with jamming leveraging varieties of defence strategies. Wireless Bluetooth network is a short range network, where the Bluetooth transceiver is operating in the 2.4 GHz ISM (industrial, scientific and medical) radio band, and a special type of frequency hopping...

Wireless sensor network (WSN) has been widely used in industrial technology, national defense, robotic system [1], medical and health field. But it is hedged about in various fields due to its security problem. Through the analysis of the characteristics of Bluetooth WSN and its security architecture, this paper gives out a security scheme for Bluetooth WSN including piconet and scatternet. Thi...

The anticipated proliferation of various wireless local area network (WLAN) enabled devices in the near future is likely to result in increased mutual interference in the 2.45GHz Industrial, Scientific and Medical (ISM) band. This work investigates the impact of standard Bluetooth and enhanced Bluetooth interference on 802.11g enabled consumer electronic devices and vice versa. Technical design...

IEEE 802.11b wireless networks and Bluetooth networks provide complimentary services using the same unlicensed radio frequency band. As the benefits of utilizing these services become increasingly apparent, the likelihood of mutual interference also increases. The wellknown frequency hopping algorithm and adaptive frequency hopping algorithm do not fully consider the interference level of the o...

Over the last years, research efforts have led the way to embed computation into the environment. Much attention is drawn to technologies supporting dynamicity and mobility over small devices which can follow the user anytime, anywhere. The Bluetooth standard particularly fits this idea, by providing a versatile and flexible wireless network technology with low power consumption. In this paper,...

Bluetooth today, has conquered almost all mobile devices including Personal Digital Assistants (PDAs), handhelds, smart phones and mobile phones. Unlike the internet, where one has to rely on a third party to provide a wireless connection, Bluetooth is inexpensive and easily available with no dependence on manufacturers or service providers and can prove beneficial in short range communication....

Bluetooth is a promising wireless technology aiming at supporting electronic devices to be instantly interconnected into short-range ad hoc networks. Recent studies show that since Bluetooth operates in the unlicensed 2.45 GHz frequency band, the presence of multiple piconets in the vicinity creates intermittent interference on signal reception which, in turn, degrades the overall throughput of...

Bluetooth security has become increasingly important since Bluetooth is going to be used as a standard technology in wireless personal communication. This is especially true for Bluetooth applications that require strong security policies, e.g. mobile commerce applications. In this paper, a Bluetooth service-level security that allows easy implementation of flexible access policies is proposed....
