Bluetooth Based Smart Sensor Networks


Bluetooth Based Smart Sensor Networks

This Electronics Engineering Seminar Topic deals with the following:

“Dragging the world towards wireless galaxy”

Various sensors are already in a broad use today as part of different devices or as standalone devices connected to a network usually to monitor industrial processes, equipments or installations. The advancements in technology, wireless communications have enhanced development of small, low power and low cost devices. Such devices when organized into a network, present a powerful platform that can be used in many interesting applications. Bluetooth is a low cost, short-range, wireless technology with small footprint, low power consumption and reasonable throughput. Bluetooth wireless technology has become global technology specification for “always on” wireless communication not just as a point-to-point but was a network technology as well. The kernel of this paper, deals about an implementation of  bluetooth based sensor networks.

The communications capability of devices and continuous transparent information routes are indispensable components of future oriented automation concepts. Communication is increasing rapidly in industrial environment even at field level.In any industry the process can be realized through sensors and can be controlled through actuators. The process is monitored on the central control room by getting signals through a pair of wires from each field device in Distributed Control Systems (DCS). With advent in networking concept, the cost of wiring is saved by networking the field devices.

But the latest trend is elimination of wires i.e., wireless networks.Wireless sensor networks – networks of small devices equipped with sensors, microprocessor and wireless communication interfaces.In 1994, Ericsson Mobile communications, the global telecommunication company based in Sweden, initiated  a study to investigate, the feasibility of a low power, low cost ratio interface, and to find a way to eliminate cables between evices. Finally, the engineers at the Ericsson named the new wireless technology as “Blue tooth”  to honour the 10(940 to 985 A.D).thcentury king if Denmark, Harald Blue tooth The goals of blue tooth are unification and harmony as well, specifically enabling different devices to communicate through a commonly accepted standard for wire less connectivity.

Bluetooth operates in the unlicensed ISM band at 2.4 GHZ frequency band and use frequency hopping spread spectrum technique. A typical Blue tooth device has a range of about 10 meters and can be extended to 100meters. Communication channels supports total bandwidth of 1 Mb / sec.  A single connection supports a maximum asymmetric data transfer rate of 721 KBPS maximum of three channels.BLUE TOOTH – NETWORKS. In bluetooth, a Piconet is a collection of up to 8 devices that frequency hop together. Each Piconet has one master usually a device that initiated establishment of the Piconet, and up to 7 slave devices. Master’s Blue tooth address is used for definition of the frequency hopping sequence. Slave devices use the master’s clock to synchronize their clocks to be able to hop simultaneously.
