On Denial of Service Attacks for Wireless Sensor Networks

On Denial-of-Service (DoS) attacks for Wireless Sensor Networks (WSNs), the authors investigated the security aspects of the physical layer. They conducted the simulative performance analysis of jamming attacks for Signal-to-Noise Ratio (SNR), Bit Error Rate (BER), network throughput and Packet Delivery Ratio (PDR) using IEEE 802.15.4 based OPNET simulative model for WSN under constant and varying intensity of jamming attacks. Under constant jamming attack, simulations revealed that average sink node PDR degrades from 79.01% in a normal scenario, to 59.22% in jammed scenario.
