چکیده
On denial-of-service (DoS) attacks for wireless sensor networks (WSNs), we investigated the security aspects of the physical layer. We 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. Also, normal scenario shows maximum PDR of 89. 68% and minimum PDR of 70. 02% while jammed scenario shows a maximum PDR of 64. 93% and minimum PDR of 49. 90%. Under varying intensity of jamming attack, simulations revealed that average sink node PDR decreases, from 79. 01% in a normal scenario, by 5. 54%, 4. 53%, 6. 36% and 3. 35% with the introduction of one, two, three and four jammers respectively. Further, the average SNR decreases, from 73. 59%, in a normal scenario, by 5. 43%, 5. 63%, 10. 44% and 20. 39% with the introduction of one, two, three and four jammers respectively.
