TCP/IP has recently taken promising steps toward being a viable communication architecture for networked sensor nodes. Furthermore, the use of Bluetooth can enable a wide range of new applications, and in this article, an overview of the performance and characteristics of a networked sensor node based on TCP/IP and Bluetooth is presented. The number of Bluetooth-enabled consumer devices on the ...

Bluetooth is a fast emerging standard for indoor pico-cellular wireless networks. Power is at a premium in typical Bluetooth devices like palmtops, PDAs, laptops and mobile phones. The Bluetooth standard defines various modes for reducing power consumption of the devices by reducing their transmission and reception activities. System throughput can be increased by keeping Bluetooth devices in l...

Ad hoc networking with Bluetooth requires an efficient way of discovering neighbor devices. Based on real-world measurements and simulations we are deriving optimal parameters for symmetric ad hoc neighbor discovery using standard Bluetooth procedures.

This paper presents an evaluation of Bluetooth positioning in a general positioning platform. Proceeding the evaluation a Bluetooth based positioning system was implemented in order to complement the theoretical evaluation with em-

Intelligent systems are driven by the latest technological advances in many different areas such as sensing, embedded systems, wireless communications or context recognition. This paper focuses on some of those areas. Concretely, the paper deals with wireless communications issues in embedded systems. More precisely, the paper combines the multi-hop networking with Bluetooth technology and a qu...

In this paper, a model for N mobile nodes that talk to one another simultaneously is considered under the following constraint: No node may transmit and receive at the same time. Furthermore, we focus on a Personal Area Network (PAN) application limiting the network to a single-hop ad-hoc network. The resulting half-duplex wireless network is an interesting special case of the general full-dupl...

The reliability of Bluetooth is discussed from technical point of view with respect of noise immunity and performance under influence of external disturbances. The emphasis is on possible industrial applications of Bluetooth technology.

Wireless networking technologies are being implemented in quite a few devices including phones, mobiles, mp3 players etc. The performance of these technologies varies from one to another. The aim of this paper is to analyze the performances of two different low power consumption technologies: Bluetooth and Zigbee. The performance parameters include data coding efficiency and transmission rate. ...

Bluetooth technology is particularly designed for a wireless personal area network that is low cost and less energy consuming. Efficient transmission between different Bluetooth nodes depends on network formation. An inefficient Bluetooth topology may create a bottleneck and a delay in the network when data is routed. To overcome the congestion problem of Bluetooth networks, a Cross-layer-based...
