Wireless Sensor Networks (WSNs) consist of the following components:

1. Sensor Nodes:

   • Small, autonomous devices equipped with sensors to monitor physical parameters.
   • Collect and transmit data to the network.

2. Communication Protocols:

   • Enable nodes to exchange data wirelessly.
   • Efficient protocols for energy conservation and reliable communication.

3. Base Station (Sink):

   • Collects and aggregates data from sensor nodes.
   • Acts as a gateway between the WSN and external networks.

4. Power Supply:

   • Batteries or energy harvesting mechanisms power sensor nodes.
   • Energy efficiency is crucial for prolonged network operation.

5. Data Processing Unit:

   • Analyzes and processes data locally on sensor nodes to reduce communication overhead.
   • Performs basic computations and filtering.

6. Networking Topology:

   • Mesh, star, or cluster topologies define how nodes are interconnected.
   • Influences communication efficiency and network resilience.

7. Security Mechanisms:

   • Implement encryption and authentication to secure data transmission.
   • Protect against unauthorized access and tampering.

8. Middleware:

   • Software layer facilitating communication and data management.
   • Offers abstraction for application development.

9. Applications:

   • Various real-world applications such as environmental monitoring, healthcare, and industrial control.
   • Tailored to specific needs using WSN data.

10. Quality of Service (QoS) Management:

    • Ensures reliable and timely data delivery.
    • Balances energy efficiency with data accuracy and latency requirements.
