Capability Analysis of Attacks in Wireless Sensor Network

Abstract

Security is key concern area in WSN as the nature of such networks makes them susceptible to various types of attacks. Driven by this, a lot of research work has been done to classify the attacks and their prevention schemes. In this paper, some well-known attacks are compared based on their severity in WSN. The behavior of black hole, gray hole and flooding attack is simulated and analyzed using ns2. The capability analysis is done on the parameters such aspacket delivery ratio, throughput, drop rate, success rate and density of packet drop, packet forward, packet sent and packet received. The analysiscompares the intensity of the attacks against each other. The simulated result shows a maximum density of packet drop in black hole attack and a minimum density of packet received in flooding attack.
