Conventional anti-jamming method mostly rely on frequency hopping to hide or escape from jammer. These approaches are not efficient in terms of bandwidth usage and can also result a high probability jamming. Different existing works, this paper, novel strategy is proposed based the idea deceiving jammer into attacking victim channel while maintaining communications legitimate users safe channel...

mobile commerce is whatever electronic transfer or transaction via a mobile modem through a mobile net in which the true value or advance payment is done for goods, services or information. a mobile payment system should be beneficial for all related persons. for a payment system to be a successful system, end-user, seller, exporter and operators should see a additional value in it. end-user pr...

In this paper, we study the problem of physical layer security in uplink millimeter-wave massive multiple-input multiple-output (MIMO) networks and propose a jamming detection suppression method. The proposed method is based on directional information received signals at base station antenna array. can accurately detect both existence direction jammer using pilot training phase. obtained then e...

The random array subset selection (RASS) jammer, which randomly selects a out of the transmit antenna from time to time, was verified effectively counter against multistatic radar system (MSRS). However, countermeasure ability RASS is restricted, because probabilities activating elements for transmission are constrained be identical. To further enhance ability, we propose resource allocation di...

Title of dissertation: SIGNALLING AND RESOURCE ALLOCATION FOR SECURE COMMUNICATION IN GAUSSIAN WIRELESS CHANNELS Shabnam Shafiee, Doctor of Philosophy, 2008 Dissertation directed by: Professor Şennur Ulukuş Department of Electrical and Computer Engineering Gaussian wireless channels are studied under two forms of security attacks: (i) the jamming attack, where the adversary is active and transm...

We consider that a transmitter covertly communicates with multiple receivers under the help of friendly jammer. The messages intended for different are transmitted in mutually orthogonal frequency bands. An adversary observes all these bands aiming at detecting whether or not communication occurs, while jammer broadcasts jamming signals to degrade detection performance adversary. block Rayleigh...
