What is Bluetooth based smart sensor networks?

A Piconet: It is an improvised network used to link wireless devices using Bluetooth technology. It is group of up to 8 devices that share similar frequencies. It uses the concept of master and slave. Each piconet has one master, and rest of the device acts as slave.

What is the function of Bluetooth sensor?

Bluetooth Beacon sensors are small transmitters that broadcast signals to close portable devices using Bluetooth Low Energy technology. They have an action range of around 90 meters and can only transmit data but cannot receive it.

What is sensor network technology?

A sensor network consists of multiple detection stations called sensor nodes, each of which is small, lightweight and portable. Every sensor node is equipped with a transducer, microcomputer, transceiver and power source. The transducer generates electrical signals based on sensed physical effects and phenomena.

What are the advantages and disadvantages of using Bluetooth based devices as a sensor network?

Advantages and disadvantages of Bluetooth

  • It avoids interference from other wireless devices.
  • It has lower power consumption.
  • It is easily upgradeable.
  • It has range better than Infrared communication.
  • The Bluetooth is used for voice and data transfer.
  • Bluetooth devices are available at very cheap cost.

Which is the core of WSN which collects data from sensors?

A WSN consists of a large number of sensor nodes that monitor and record the physical conditions of an environment, and the sensor data are collected at a so-called sink node.

What is Bluetooth and its types?

It is a Wireless Personal Area Network (WPAN) technology and is used for exchanging data over smaller distances. This technology was invented by Ericson in 1994. It operates in the unlicensed, industrial, scientific and medical (ISM) band at 2.4 GHz to 2.485 GHz.

What is a Bluetooth sensor?

Android. The Bluetooth sensor logs the mobile device’s Bluetooth sensor and detects surrounding Bluetooth-enabled and visible devices with respective RSSI dB values at specified intervals (default is 60 seconds). A scan session assigns the same timestamp for all the found Bluetooth devices.

What are the different types of wireless sensor networks?

Types of Wireless Sensor Networks

  • Terrestrial WSNs.
  • Underground WSNs.
  • Underwater WSNs.
  • Multimedia WSNs.
  • Mobile WSNs.

What is the main limitation of Bluetooth?

There are some important disadvantages of Bluetooth are given below, It can lose connection in certain conditions. It has low bandwidth as compared to Wi-Fi. It allows only short range communication between devices.
