Secure Aggregation in Wireless Sensor Networks: A Review

Rakesh Sharma, Matish Garg, Pinki Sharma


A wireless sensor network generally consists of huge range of inexpensive densely deployed detector nodes that have strictly forced sensing, computation, and communication capabilities. Due to resource restricted detector nodes, it is necessary to scale back the number of data transmission in order that average time period of detector and so the information measure consumption square measure improved. Knowledge aggregation is that the strategy of summarizing and mixing detector knowledge thus on minimizes the number of data transmission within the network. Wireless sensor networks square measure generally deployed in remote and hostile environments to transmit sensitive knowledge, detector nodes square measure in peril of node compromise attacks and security problems like knowledge confidentiality and integrity square measure very necessary. Therefore, wireless sensor network protocols, e.g., knowledge aggregation protocol, need to be designed with security. During this paper we have a tendency to investigate the link between security and knowledge aggregation methodology in wireless detector networks.
