A Survey on Security Attacks in Wireless Sensor Networks

Satveer Kaur, Nitika Goyal


Wireless sensor networks have become an emergent
area of research and development due to the marvelous number
of applications such as battlefield, building, traffic surveillance,
habitat monitoring and smart homes and many more. These
applications can greatly benefit from such systems. The area has
lead to the development of tiny, cheap, disposable and self
contained battery powered computers. These computers are
known as sensor nodes or “motes”. These can accept input from
an attached sensor, process input data and transmit the results
wirelessly to the transit network. These networks are easily
prone to security attacks due to the wireless nature as after
deployment; these networks are unattended and nodes are often
placed in a hostile or dangerous environment where they are
physically unprotected. The inherent power and memory
limitations of sensor nodes make conventional security solutions
unfeasible. There are a lot of attacks which affect the WSN’s
security. Some of these attacks are selective forwarding,
sinkhole, denial of service etc. In this paper, we discussed about
all these security attacks faced by WSNs.
