What do you mean by sensor network explain?
A sensor network is a group of sensors where each sensor monitors data in a different location and sends that data to a central location for storage, viewing, and analysis.
What is the role of sensor networks?
The sensor network connects to the internet or computer networks to transfer data for analysis and use. Sensor network nodes cooperatively sense and control the environment. They enable interaction between persons or computers and the surrounding environment.
What are the basic components of sensor network?
A sensor node is made up of four basic components such as sensing unit, processing unit, transceiver unit and a power unit which is shown in Fig. 5. It also has application dependent additional components such as a location finding system, a power generator and a mobilizer.
What is sensor network and its applications?
Wireless Sensor Network (WSN) is an infrastructure-less wireless network that is deployed in a large number of wireless sensors in an ad-hoc manner that is used to monitor the system, physical or environmental conditions.
What are sensor networks in IoT?
An IoT (Internet of Things) Wireless Sensor Network (WSN) refers to a group of spatially dispersed and dedicated sensors for monitoring, and recording the physical conditions of the environment, and collectively pass on such data through a wireless network to a internet-based location.
What are advantages of sensor networks?

What is the importance of sensors?
Sensors can improve the world through diagnostics in medical applications; improved performance of energy sources like fuel cells and batteries and solar power; improved health and safety and security for people; sensors for exploring space and the known university; and improved environmental monitoring.
What is sensor network architecture?
The wireless sensor network architecture is built with nodes that are used to observe the surroundings like temperature, humidity, pressure, position, vibration, sound, etc.
What is the advantages of sensor network?
➨It is scalable and hence can accommodate any new nodes or devices at any time. ➨It is flexible and hence open to physical partitions. ➨All the WSN nodes can be accessed through centralized montoring system. ➨As it is wireless in nature, it does not require wires or cables.
What are sensor network scenarios?
4 Sensor network scenarios: (a) single-hop, heterogenous, stationary network; (b) multi-hop , homogeneous, stationary network; (c) multi-hop, heterogeneous, stationary network; (d) single-hop , homogeneous, stationary network with a mobile sink. Source publication.
