As Unmanned Aerial Vehicles (UAVs) become increasingly integral to a variety of industries, their dependency on radio frequency (RF) signal-based communication systems has exposed them to a multitude of security vulnerabilities. One of the most notable ...

The inherent openness of wireless communication techniques has made them vulnerable to jamming attacks. However, the effectiveness of a jamming attack depends on numerous parameters and varies according to the state of the environment. At the same time, ...

Towards sixth-generation networks (6G), satellite communication systems, especially based on Low Earth Orbit (LEO) networks, become promising due to their unique and comprehensive capabilities. These advantages are accompanied by a variety of challenges ...

In this study, the authors review various jamming and anti‐jamming strategies in the context of cognitive radios (CRs). The study explores different jamming models and classifies them according to their functionality. Furthermore, a study of jamming ...

Wireless networks are prone to jamming-type attacks due to their shared medium. An attacker node can send a radio frequency signal and if this signal interferes with the "normal" signals of two communicating nodes, the communication can be severely ...

Integrating Cognitive Radio (CR) technology in Internet-of-Things (IoT) devices allows efficient large-scale deployment of IoT systems. Recently, research efforts are shifted toward adopting CR in IoT as a response for the spectrum scarcity problem. ...

Wireless networks are prone to jamming attacks due to the broadcast nature of the wireless transmission environment. The effect of jamming attacks can be further increased as the jammers can focus their signals on reference signals of the transmitters, ...

Randomized exponential backoff is a widely deployed technique for coordinating access to a shared resource. A good backoff protocol should, arguably, satisfy three natural properties: (1) it should provide constant throughput, wasting as little time as ...

Recent surges in the development of underwater acoustic networks UANs have lead to a rapid acceptance of this technology in scientific, commercial, and military applications. However, limited work has been performed on developing secure communication ...

Smart grid is a cyber-physical system that integrates power infrastructures with information technologies. To facilitate efficient information exchange, wireless networks have been proposed to be widely used in the smart grid. However, the jamming attack ...

Vehicular ad hoc network (VANET) is currently researched and achieved by several organizers to develop the intelligent transportation system (ITS). Research on Vehicular Ad hoc Network (VANET) has been conducting for long time. Nowadays, several ...

The broadcast nature of wireless networks has been widely exploited by adversaries in order to cause severe denial-of-service attacks. Several algorithms are proposed in the literature for the detection and mitigation of such attacks at the physical and ...

In the spirit of competitive analysis, approximation guarantees, and game-theoretic treatments, we introduce an approach to evaluating the performance of attack-resistant algorithms in distributed systems. This new approach, which we call resource-...

Consider a time-slotted, single-hop, wireless sensor network consisting of n correct devices and and f•n Byzantine devices where f≥0 is any constant; the Byzantine devices may or may not outnumber the correct ones. There exists a trusted sender Alice ...

In order to provide security services in wireless sensor networks, a well-known task is to provide cryptographic keys to sensor nodes prior to deployment. It is difficult to assign secret keys for all pairs of sensor node when the number of nodes is ...

Wireless networks have been among the main trends during the last few years. Their low-cost deployment and ubiquitous coverage have enabled the provision of numerous services to the end-users. Wireless local area networks (WLANs) are capable of ...

Imagine that Alice wants to send a message m to Bob, and that Carol wants to prevent this. Assume there is a communication channel between Alice and Bob, but that Carol is capable of blocking this channel. Furthermore, there is a cost of S dollars to ...
