On Denial of Service Attacks for Wireless Sensor Networks
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 inten...
متن کاملMitigating denial of service attacks in hierarchical wireless sensor networks
It is easy to see how these functions work in unison with each other. For example, attackers often use email to send malicious URLs to users. These may be spotted by email protection functions within a unified threat management system or Internet security appliance. However, if they slip through, they will be caught by the web filtering mechanism, making it doubly hard for attackers to compromi...
متن کاملDenial of Service Attacks and Challenges in Broadband Wireless Networks
Broadband wireless networks are providing internet and related services to end users. The three most important broadband wireless technologies are IEEE 802.11, IEEE 802.16, and Wireless Mesh Network (WMN). Security attacks and vulnerabilities vary amongst these broadband wireless networks because of differences in topologies, network operations and physical setups. Amongst the various security ...
متن کاملLightweight Detection of Denial-of-Service Attacks in Practical Wireless Sensor Networks: A Systematic Approach
Wireless sensor networks (WSNs) are especially susceptible to denial-of-service attacks due to the resourceconstrained nature of motes. We follow a systematic approach to analyze the impacts of these attacks on the network behavior; therefore, we first identify a large number of metrics easily obtained and calculated without incurring too much overhead. Next, we statistically test these metrics...
متن کاملDistributed Denial of Service Attack Detection in Wireless Sensor Networks
Wireless sensor networks have emerged as a significant source for the study and analysis of data from the environment. These networks are deployed in harsh and inaccessible environments with the purpose of monitoring their respective surroundings, and generating observed readings, for delivery to a centralised entity, for further data analysis. Sensor nodes are tiny devices with limited availab...
