Abstract – Wireless sensor networks – networks of small devices equipped with sensors, microprocessor and wireless communication interfaces – are a technology that has gained a lot of interest lately. The broad spectrum of new and interesting applications, ranging from personal health-care to environmental monitoring and military applications, is proposed for such networks.
Various wireless technologies, like simple RF, Bluetooth,
UWB or infrared might be used for communication between sensors. In this paper the main principles, applications and issues of Bluetooth based wireless sensor networks, as well as an implementation of a simple Bluetooth based sensor network are described. The main problems experienced during the implementation and applied solutions are presented. 1. Introduction
In [1], a vision, called ubiquitous computing, of the world where humans and computers were seamlessly united is described. The essence of the vision was the creation of environments saturated with computing and communication in an unobtrusive way. Recently, WWRF (Wireless World
Research Forum) and ISTAG (IST Advisory Group) released their visions of the future communication networks [2], [3].
Both institutions envisage a vast number of various intelligent devices, embedded in the environment, sensing, monitoring and actuating the physical world, communicating with each other and humans.
Today, we are witnessing a rapid proliferation of various wireless devices with considerable computing power and fairly small size. These devices are still not, to paraphrase
Marc Weiser [1], indistinguishable from the fabric of everyday life, but are becoming a part of that fabric
(Bluetooth headset built as a part of jewellery for example).
Various sensors are already in a broad
