The use of energy harvesting as a counter-jamming measure is investigated on the premise
that part of the harmful interference can be harvested to increase the transmit power. We …

Jamming attacks represent a critical vulnerability for wireless secret key generation (SKG)
systems. In this paper, two counter-jamming approaches are investigated for SKG systems …

Anti-jamming interference alignment (IA) is an effective method for battling adversarial
jammers for IA networks. Nevertheless, the number of antennas may not be enough to make …

Due to the broadcast nature of the wireless medium, wireless networks are highly
susceptible to jamming attacks. Such attacks are often studied in a game theoretic …

In wireless networks, jamming is an easily mountable attack with detrimental effects on the
victim network. Existing defense strategies mainly consist of retreating from the jammer or …

In this paper, we propose using a wireless-powered friendly jammer to enable secure
communication between a source node and destination node, in the presence of an …

Friendly jamming is an unconventional approach to secure wireless communications.
Specifically, a friendly jammer transmits jamming signals to an eavesdropper while a …

Wireless networks are susceptible to accidental or intentional radio interference. One way to
cope with this threat is to have the radios compete with the jammer, whereby the network …

We address the problem of passive eavesdroppers in multi-hop wireless networks using the
technique of friendly jamming. The network is assumed to employ Decode and Forward (DF) …

The effectiveness and the simple implementation of physical layer jammers make them an
essential threat for wireless networks. In a multihop wireless network, where jammers can …
