Nowadays, there is an increasingly stronger trend to integrate a multitude of functionalities into a single device. Traditionally, this has been achieved by utilizing more powerful general-purpose processors to handle the additional workload. Since then, application-specific processors (acting as co-processors or hardware accelerators) were introduced to offload part of these workloads and to m...

PERFORMANCE OF BLUETOOTH TECHNOLOGIES AND THEIR APPLICATIONS TO LOCATION SENSING BY Abhishek Pramod Patil Location-aware computing is regarded as a key feature of many future mobile applications, especially with the convergence of wireless technologies and mobile systems. GPS serves well for most outdoor applications, but it cannot be used in indoor location sensing. Several approaches have bee...

Bluetooth is a promising new technology for short range, low power, low cost, pico-cellular wireless connectivity between mobile devices. Efficient clustering or topology construction algorithms play a very important role in the fast connection establishment of such networks. The performance of these algorithms is mainly dependent on the device discovery time, i.e., the time taken by a node to ...

While the market for fixed, wired personal computers shows stagnating tendencies, mobile computing receives more and more attention. The terms # : 0 and 0 have moved into the center of interest. Truly mobile devices such as mobile phones, digital watches, and personal digital assistants (PDA) become more and more powerful. At the same time, notebook devices are decreasing in size and weight. As...

Bluetooth is a new wireless data communications technology due to reach consumer markets later this year. This thesis presents the work done in using open-source protocol stacks to write Bluetooth-enabled applications. The development of a client-server software program used to study the effect of interference from a wireless local area network is described. The results found are significantly ...

This paper describes a new protocol for the establishment of multihop ad hoc networks based on Bluetooth devices. The protocol proceeds in three phases: device discovery, partitioning of the network into Bluetooth piconets, and interconnection of the piconets into a connected scatternet. The protocol has the following desirable properties: It is executed at each node with no prior knowledge of ...

The emergence of Bluetooth as a default radio interface has allowed handheld electronic devices to be instantly interconnected as ad hoc networks. These short-range ad hoc wireless networks, called piconets, operate in the unlicensed 2.4-GHz ISM (Industrial-Scientific-Medical) band where devices may be used to configure single or overlapping piconets, know as scatternet. As all piconets operate...

Bluetooth is a most promising technology designed for the wireless personal area networks for the cable replacement. In this paper, a location aware mobility based routing scheme for the Bluetooth scatternet is proposed that constructs the links dynamically. Our proposed routing protocol requires location information of the nodes and constructs the route between any source and destination and r...

Bluetooth is a radio technology for Wireless Personal Area Networks operating in the 2.4 GHz ISM band. Since both Bluetooth and IEEE 802.11 devices use the same frequency band and may likely come together in a laptop or may be close together at a desktop, interference may lead to significant performance degradation. The main goal of this paper is to propose a scheduling algorithm aimed at reduc...

Studies of mobile ad-hoc networks are often based on simulation and their underlying, necessarily simplified assumptions of physical reality. In order to analyse the practical problems we built our own hardware and software. The hardware consists of a core Motorola controller and different wired and wireless interfaces like a Bluetooth and a 433/868 MHz RF module. It allows therefore analysing ...
