This paper presents malicious relay node detection in a cooperative network using
unsupervised learning based on the received signal samples over the source to destination …

Relay attacks are passive man in the middle attacks, aiming to extend the physical distance
of devices involved in a transaction beyond their operating environment, within the restricted …

With the widespread use of the Tor network, attackers who control malicious relays pose a
serious threat to user privacy. Therefore, identifying malicious relays is crucial for ensuring …

For Long Term Evolution Advanced (LTE-A) network, although there exist many studies that
focus on improving the performance with relays, security issues are often neglected. Due to …

Mobile Adhoc Networks (MANET) are infra structure-less network made up of many mobile
nodes and these nodes communicate through a wireless and infrastructure less medium …

In fifth generation (5G) networks, cooperative transmission assisted by relays is believed to
be an essential element, which significantly improves the system reliability and enhances …

Internet of Things (IoT) network is vulnerable to various cyberattacks, especially insider
attacks. Most existing studies mainly detect nontargeted insider attackers, who manipulate …

SDN is a modern internet architecture that has transformed the traditional internet structure
in recent years. By segregating the control and data planes of the network, SDN facilitates …

Clustering Internet of Things (IoT) networks, to alleviate the network scalability problem,
provides an opportunity for an adversary to compromise a set of nodes by simply …

As one of the highly used components in the power system, digital relays are employed to
use the phasor measurement units', voltage, and current signals, to decide whether a fault …
