Wireless Sensor Networks (WSNs) are one of the most widely used technologies in our daily lives. However, since wireless sensor networks are based on communication within radio channels, WSNs are susceptible to malicious attempts to block the channel. One of the most frequently used attacks is a jamming attack. This type of attack not only blocks the ongoing communication but also exhaust the e...

Chaos-based communication systems are known to offer advantages that are shared by spread-spectrum communications. One important aspect of performance of any spreadspectrum communication system is the ability to resist jamming. This area of study, however, is not available in the literature. In this paper, the anti-jamming performance of the coherent CSK system is presented. Two common types of...

The problem of networked control under disturbance and jamming attacks is investigated. Specifically, the control input packets are assumed to be transmitted from the controller to a linear plant over an insecure wireless communication channel that faces jamming attacks. The likelihood of transmission failures on this channel depends on the power of the jamming interference signal emitted by an...

Due to its capability to resist jamming signals, chirp spread spectrum (CSS) technique has attracted much attention in the area of wireless communications. However, there has been little rigorous analysis for the performance of the CSS communication system in jamming environments. In this paper, we present analytic results on the performance of a CSS system by deriving symbol error rate (SER) e...

In the condition of complex electromagnetic environment and multifarious methods activate jamming, anti-jamming approach has been highlighted. Anti-jamming method based on waveform entropy is used to counter nonsynchronous short pulse jamming because its low compute complexity easy implementation. This paper analyzes performance, obtain decision threshold value by taking use kernel function, ex...

This letter proposes a novel UAV-enabled mobile jamming scheme to improve the secrecy rate of ground wiretap channel. Specifically, a UAV is employed to transmit jamming signals to combat against eavesdropping. Such a mobile jamming scheme is particularly appealing since the UAV-enabled jammer can fly close to the eavesdropper and opportunistically jam it by leveraging the UAV’s mobility. We ai...

We have studied kinetics of random sequential adsorption of mixtures on a square lattice using Monte Carlo method. Mixtures of linear short segments and long segments were deposited with the probability p and 1− p, respectively. For fixed lengths of each segment in the mixture, the jamming limits decrease when p increases. The jamming limits of mixtures always are greater than those of the pure...

The 802.15.4 Wireless Sensor Networks (WSN) becomes more economical, feasible and sustainable for new generation communication environment, however their limited resource constraints such as limited power capacity make them difficult to detect and defend themselves against variety of attacks. The radio interference attacks that generate for WSN at the Physical Layer cannot be defeated through c...

Defense against denial of service (DoS) attacks is a critical component of any security system as these attacks can affect the availability of a node or an entire network. In this work, we focus on jamming type DoS attacks at the physical and MAC layers in 802.11 based ad hoc networks. Collisions in wireless networks occur due to varying factors such as jamming attacks, hidden terminal interfer...
