  Frequently Asked Questions

  What are Wireless Sensor Networks (WSNs)?

  WSNs are integrated technologies using sensors and wireless networks for applications like environmental monitoring, security, and disaster management.

  Why is energy efficiency critical in WSNs?

  WSNs often operate in harsh or remote environments with limited energy supplies that cannot be easily recharged or replaced.

  What is the role of clustering in WSNs?

  Clustering groups nodes to reduce routing overhead, conserve bandwidth, and save energy by designating a cluster head to aggregate and transmit data.

  What is the LEACH algorithm?

  LEACH (Low-Energy Adaptive Clustering Hierarchy) is a classic clustering protocol that uses randomized rotation of cluster heads to distribute energy consumption.

  Which algorithm performed better in the simulation?

  Simulation results showed that the S-Web clustering mechanism achieves a noticeable improvement in network lifetime compared to LEACH.
