A Complete Study on the Security Aspects of Wireless Sensor Networks

The wireless sensor network is an upgrade of the wireless network; all the nodes are connected in an ad hoc basis. Security of wireless sensor network plays a major role while building a securied application on WSN (wireless sensor network). This paper talks about the complete study on the security aspects of the WSN. Initially, the architecture of the WSN is discussed with all the five layers and the cross planes. The basic security goals are discussed under primary and secondary. Each and every layer is prone to some kind of attack. The various attacks in all the layers are explained in detail, and the countermeasure for the same is discussed. Finally, the research area in the WSN is discussed for the future upgrades.
