A Brief Study on Security Preserved Data Aggregation Approaches in WSN s

Wireless sensor networks (WSNs) are networks of dedicated, spatially scattered sensors that track and record environmental and physical variables and transmit the gathered information to a centralized point. The size and processing power of wireless sensor nodes are relatively small, and they have very little battery life. Resources including energy, memory, computing speed, and communications bandwidth are limited by size and cost restrictions. By minimizing duplication, data aggregation allows us to conserve these resources and cut down on energy usage. Another crucial necessity when sending information from sensor nodes to the base station is data security. Some of the power-saving and privacy-preserving techniques utilized for data aggregation in WSNs are discussed in this work.
