• Process: Techniques include redundancy (having backup nodes), error detection and correction protocols, and re-routing data through alternative paths if a node fails.

9. Security

• Function: Protecting data and maintaining network integrity is essential.
• Process: Security measures might include encryption for data transmission, authentication protocols to verify node identities, and secure key management practices to prevent unauthorized access.

10. Self-Organization

• Process: Self-organization involves dynamically adjusting network parameters, updating routing tables, and reorganizing the network topology as needed.

11. Communication Modes

• Function: Nodes can operate in different communication modes based on their role.
• Process: Modes include data collection (sensing), data forwarding (routing), and data aggregation (processing). Nodes might switch between these modes based on network conditions or specific tasks.

By efficiently managing these behaviors, sensor nodes contribute to the overall effectiveness and longevity of Wireless Sensor Networks, ensuring that they can operate reliably and meet the demands of various applications.
