Attacks on Wireless Sensor Networks: A Survey
Wireless sensor network platforms are less expensive and more powerful having tiny electronic devices called motes (sensor nodes). Wireless sensor networks enhance its popularity in military and health centric research areas; now it is also popular in industrial area. This paper describes the security requirements as WSNs are easily prone to more attacks than wired networks. This paper studies the security attacks in WSNs that are popular now-a-days. This paper also elaborate the most popular attack i.e. wormhole attack and their countermeasures in the network layer.
