Wireless Sensor Network or WSN is a spatially distributed network of sensor nodes to track environmental and physical conditions like temperature, pressure, humidity etc. This data is transferred to a central location through the network. The main components of this network are:
Transducer – To generate electrical signals.
Microprocessor – To process and store collected data.
Transceiver – To transmit and receive signals.
Battery – To provide power to the sensor nodes
This network can have a star topology, tree topology or mesh topology based on the requirement.
Characteristics of Wireless Sensor Networks
WSN has the following main characteristics
Constraints on nodes regarding power consumption following the concept of energy harvesting.
Adaptability to node failures.
Design of the network is cross-layer.
Highly scalable network.
- Easy deployment.
Applications of Wireless Sensor Networks
Rapid Emergency Response.
- Dynamic Routing Management.
