We study the fundamental problem of how devices, operating over a wireless medium, can discover potential communication partners. For the devices, the spectrum is divided into m frequency channels. As multiple devices share these channels, they have to cope with collisions while they are trying to find other devices in the system. Moreover, we assume an adversarial jammer to block some of the a...

Jamming sensor attacks localization is a significant area that acquires considerable research interest. This interest is expected to grow further with the prolifiration of wireless sensor network applications due to the physical share environment. Jamming attacks emitting a radio frequency signals by the adversaries and impact the wireless sensor network localization tactic. Also the jamming at...

Unmanned aerial vehicles (UAVs) are widely considered as key enablers for future wireless networks due to their advantages, such high mobility and flexible deployment. In this paper, the UAV assisted secure communication system is investigated, where deployed mobile jammer prevent eavesdropper from overhearing confidential message. With objective of maximizing secrecy rate, a joint optimization...

In this article, we investigate the resilience of Massive MIMO Physical Layer Network Coding (PNC) to jamming attack in both sub-6 GHz and millimeter-Wave (mmWave) systems vehicular networks. generally is resilient attacks, impact that PNC has on resilience, if combined with MIMO. The combination shown a significant improvement bit error rate (BER) our previous investigation. corresponding fram...

Music generation remains an attractive and interesting application of machine learning since it is typically characterized by human ingenuity and creativity. Moreover, given the high-dimensionality of time-series data, it is difficult to construct a model that has the representational power necessary to capture the timeand note-invariant patterns throughout a musical piece. In this paper, we de...

The Internet of Things (IoT) immensely benefits from wireless sensor networks (WSNs). Unfortunately, WSNs, by virtue being low-power, are vulnerable to physical jamming attacks. This letter focuses on WSNs with multiple gateways where potentially many sensors under the attack a smart jammer. jammer can observe communication links and selectively jam transmission some such that throughput WSN is...

Most of the current anti-jamming algorithms for wireless communications only consider how to avoid jamming attacks, but ignore that communication waveform or frequency action may be obtained by jammers. Although existing methods can guarantee temporary effects, long-term performance these depressed when intelligent jammers are capable learning from historical activities. Aiming at this issue, a...

The IEEE 802.11 protocol inherently provides the same long-term throughput to all the clients associated with a given access point (AP). In this paper, we first identify a clever, low-power jamming attack that can take advantage of this behavioral trait: the placement of a low-power jammer in a way that it affects a single legitimate client can cause starvation to all the other clients. In othe...

NAVSYS High Gain Advanced GPS Receiver (HAGR) uses a digital beam-steering antenna array to provide additional gain in the direction of the GPS satellite signals. This increases the received signal/noise ratio on the satellites tracked and also improves the accuracy of the pseudo-range and carrier-phase observations. The directivity of the digital beams created from the antenna array also reduc...
