Secure Data Aggregation Types in Wireless Sensor Networks: A Review

Abstract

With pace of time there is huge development in the field of advances of WSN (Wireless Sensor Networks) that leads to many emerging applications like target tracking application. Sensor nodes spend most of their energy during data transmission. With data aggregation, one can eliminate the redundant data transmission and so reduce the energy consumption. Sensor nodes are set up in a varied adverse environment which often compromise. So the maintenance of parameters of security such as confidentiality, integrity, authentication and availability become crucial. Nowadays there are many fields where wireless sensor network can be used like health care monitoring, earth/environmental sensing, climate observation, air pollution monitoring, forest fire detection as well in wearable devices, target-tracking. Prior transform it into valuable information that is essential to decide the degree of data aggregation due to scarcity of network management and controlling systems. Because of restricted transmission area of sensors, they couldn’t be used in huge geo graphical areas. There is some network management tools required in huge area networks for the development of the huge scale sensor network such as routing and data aggregation etc.
