A Review of Wireless Sensor Network Data Aggregation Techniques' Privacy and Energy- Efficiency: Exploring Privacy and Energy-Efficient Data Aggregation Techniques in Wireless Sensor Networks

Abstract

Wireless sensor networks (WSNs) are made up of tiny sensor nodes dispersed across a largearea for the purposes of sensing and data processing. They can't store much information in their memoryand have a small amount of energy. Extensive amounts of power are used during the sensing,processing, transmission, and receipt of sensed data. That's why these sensor nodes are acting up. It ispossible to extend the life of a network and circumvent these constraints by employing a variety of dataaggregation strategies. With data collecting, the sink node collects and aggregates relevant data in aneffective manner while minimising energy use. The lifespan of the network may be lengthened, andredundant data can be eliminated. This study provides a comprehensive overview of energy-efficientdependent data aggregation strategies for wireless sensor networks. Different data aggregationstrategies in wireless sensor networks (WSN) are addressed, along with their energy efficiency andprivacy implications.
