Today, we are going to know about the “Bluetooth Based Smart Sensor Networks.“A technology that has gained a lot of interest during recent times is wireless sensor networks. Networks of small devices equipped with sensors, wireless communication interfaces, microprocessors, etc. Personal health care systems, environmental monitoring, military applications, etc., are some of the new and exciting applications of the broad spectrum of wireless sensor networks.
Wireless technologies such as Bluetooth, infrared, radio frequency (RF), ultra-wideband (UWB) are all mainly get utilize for communications between sensors. Such sensor networks consist of many small devices equipped with a sensing unit, microprocessor, wireless communication interface, and a power source.
History of Bluetooth Smart Sensor Networks
Bluetooth is a wireless data transfer technology with a short range of 10-100 meters and has a bandwidth of 1 Mbps. It usually operates on 2.45GHz radio signals and has maximum asymmetric data transfer rate of 721 Kbps. Bluetooth Wireless Technology (BWT) was first initiated in the year 1989 by Nils Rydbeck in Sweden.
It was initially built to get rid of cable connections between PDAs and notebook PCs. Later on, it was accepted as the standard for wireless connectivity. They operate at 2.145 GHz in a license-free globally available ISM radio band. They’re worldwide available and compatible.
Types of Connection in Bluetooth
There are two main topologies, depending on the type of connection that needs to be set between Bluetooth devices:
- PICONET Topology: – It comprises 8 Bluetooth wireless technology-enabled devices. When PICONET comes into presence one device sets up the frequency bouncing pattern and the leftover devices synchronize their signals to the pattern set up. To set up PICONET nearby Bluetooth devices are get discover by an inquiry procedure.
2. SCATTERNET Topology: – It consists of numerous PICONETS connected by devices taking part in multiple PICONET. At the same time, interfacing through SCATTERNET devices can be slaves in all PICONETS or masters in one PICONET and slaves in others. The benefit of SCATTERNET is there can be multi-hop connections between devices in different PICONET.

Advantages of Bluetooth
- It is effectively upgradeable.
- Bluetooth is likewise getting utilize for voice chat and information transfer.
- The power utilization of Bluetooth is very less.
- Bluetooth devices are accessible at cheap costs.
- Since it has no line of sight it can go through any objects with no check.
- Free to utilize if the device has Bluetooth.
- It avoids interfering with different wireless devices.
- It has a superior reach to infrared communication.
- Gets used in headsets, GPS, printers, webcams, keyboards, mouse, and so on
Disadvantages of Bluetooth
- Its bandwidth is low contrasted to Wi-Fi.
- Can be effectively hacked.
- Simply restricted to short-range.
- It can easily lose connection under specific situations.
- It additionally has a short battery life compared to others.
Wireless Sensor Networks (WSN)
Wireless Sensor Networks (WSN) are several little devices furnished with detecting units, microprocessors, wireless communication interfaces, and a power source.
Two primary operations that WSN performs are:
- QUERING: – Queries are gets being used only when the user needs only the current estimation of an observation.
- TASKING: – It gets being used when an occasion must be examine throughout a long period of time making it a more complex activity.
The primary two examination issues concerning Bluetooth Based Smart Network are: –
- Issues in the advancement of hardware.
- Issues in the advancement of programming.
Types of Wireless Sensor Networks
Terrestrial WSNs: – They’re capable of passing on base stations efficiently. It consists of several hundred to thousand wireless sensor nodes arranged in either an unstructured manner or in a structured way.
Underground WSNs: – They’re costly compared to terrestrial WSNs. It consists of numerous nodes that are placed underground to sift through the confidential situation.
Underwater WSNs: – The network consists of many nodes and vehicles. Such a network can be placed underwater for collecting data from these sensor nodes. The main disadvantage is reproduction delay and sometimes bandwidth and sensor failures.
Multimedia WSNs: – This type of sensor gathers images in the form of multimedia like images, videos, and audio. They consist of cheap price sensors re-equipped with microphones and cameras.
Mobile WSNs: – These consist of sensor nodes that can be move around from one place to another. They can interact with the physical environment. The Mobile WSNs network includes better and improved coverage, superior channel capacity, etc. they’re much more flexible than static sensors.

Advantages of Bluetooth Based Wireless Sensor Network
- An example of a bluetooth based smart sensor networks can be explain in a small house. You could probably cover the furthest reaches with only a select dew sensor nodes or you may be able to cover the small area with a centrally located access point and avoid using sensor nodes at all. Short-range remotes that have complete control over televisions, gaming consoles, or smart home lighting are examples of good Bluetooth-based networks.
2. Nearly almost all the new vehicles are Bluetooth-enabled. This lets you listen to music on your phone or attend a call and talk through car speakers. Vehicles provide an excellent sophisticated Bluetooth environment because all the devices are very close to each other and can operate without any complications.
Disadvantages of Bluetooth Based Wireless Sensor Network
- If you’re considering merging a Bluetooth-based smart sensor network at a large area like a college campus then you might want to opt for different sensor technology. Not only will the range be difficult to tackle and since it works only on the close range it will seriously be a major issue but you’ll be trying to work in a congested band with interference problems. This is where dependability will become a huge matter.
2. If you’re trying to plan a Bluetooth network that is constantly moving or a dynamic radio frequency environment, you’re in for a challenge. Determining how to ensure that your sensor nodes can easily talk to your gateway is challenging enough, but it’ll be even more difficult if part of your network is mobile.
So this is all about “Bluetooth Based Smart Sensor Networks.” Info At One believes that we should upgrade our technical knowledge with growing technology. Therefore we always try to serve you guys the best information regarding the technology.
