Cooperative diversity protocols are designed with the assumption that terminals always help each other in a socially efficient manner. This assumption may not be valid in commercial wireless networks where terminals may misbehave for selfish or malic

Spectrum sensing is of utmost importance in cognitive radio and dynamic spectrum access systems for achieving spectrum awareness. To provide reliable spectrum awareness, it is critical to develop (near-) optimal sensing techniques and understand achi

CoopMAC has been recently proposed as a possible implementation of cooperation protocols in the medium access control (MAC) layer of a wireless network. However, some nodes may refrain from cooperation for selfish purposes, e.g. in order to save ener

Spectrum congestion is a problem to both commercial and military systems. A recent Presidential Council of Advisors on Science and Technology (PCAST) study suggests that this problem is further amplified for military systems because not only demand f

Cognitive interference, which can adapt its strategy to the states of the environment and legitimate system, is a serious threat to wireless communication systems or even more general systems such as smart grids. The interferer can also disguise itse

In cognitive radio systems, the available frequency bands are usually non-contiguous, which may cause impact on the spectrum utilization efficiency (SUE).When the receiver has a limited sampling capability, the aliasing phenomenon may cause interfere

Unmanned aerial vehicles (UAVs) can be used to chase radio frequency (RF) emitters by sensing the signal sent out by the RF emitters. Meanwhile, the RF emitter can evade from the UAVs, thus forming a pursuit-evasion game. In contrast to traditional p

Primary user emulation attack, which targets distabilizing the queuing dynamics of cognitive radio networks, is studied using game theoretic argument. The attack and defense are modeled as a stochastic game. The Nash equilibrium of the game is studie

In this work, we consider the challenge of designing an effective networked EW operation against a sophisticated adversary that uses different types of wireless triggers to detonate radio controlled improvised explosive devices. We assume that jammin
