Explain leach protocol

Question

Accepted Answer

Leach protocol is a routing protocol used in wireless sensor networks for data aggregation and transmission.

Leach stands for Low Energy Adaptive Clustering Hierarchy.
It is a hierarchical protocol where nodes are organized into clusters.
Each cluster has a cluster head that collects and aggregates data from member nodes.
Cluster heads transmit the aggregated data to a base station.
Leach protocol uses randomized rotation of cluster heads to distribute energy consumption evenly.
It helps in reducing energy consumption and prolonging network lifetime.
Leach protocol is suitable for applications where energy efficiency is crucial, such as environmental monitoring or surveillance systems.
