Detection of Selective Forwarding Attacks in Wireless Sensor Networks: A Survey

A Wireless Sensor Network (WSN) consists of distributed an autonomous devices that monitors both physical and environmental conditions. Sensor Networks are used for weather prediction and measuring temperature, sound, wave, vibration, pressure etc. Sensor Networks suffer from various security attacks like (i) sink hole attack, (ii) black hole attack, (iii) wormhole attack and (iv) selective forwarding attacks. Selective forwarding attack happens in compromised nodes by dropping packets selectively. This paper surveys various techniques for detecting selective forwarding attacks in WSNs.
