Secure Collaborative Spectrum Sensing in the Presence of Primary User Emulation Attack in Cognitive Radio Networks

Collaborative Spectrum Sensing (CSS) is an effective approach to improve the detection performance in Cognitive Radio (CR) networks. Inherent characteristics of the CR have imposed some additional security threats to the networks. One of the common threats is Primary User Emulation Attack (PUEA). In PUEA, some malicious users try to imitate primary signal characteristics and defraud the CR user...

NEAT: A NEighbor AssisTed Spectrum Decision Protocol for Resilience against Primary User Emulation Attacks

We propose a distributed spectrum decision protocol resilient to primary user emulation attacks (PUEA) in dynamic spectrum access (DSA) networks. PUEA is a type of denialof-service attack that can result in unreliable and/or disconnected DSA networks by depriving legitimate secondary users of spectrum access. We first propose an individual detection mechanism for secondary users to achieve prel...

A Cyclostationarity-Based Spectrum Sensing Scheme for Cognitive Radios With Dynamic Primary User Signals

This paper addresses a cyclostationarity-based spectrum sensing scheme for cognitive radios in dynamic primary user (PU) traffic environments where the PU might randomly depart or arrive during the sensing period. At first, the spectrum sensing problem in dynamic PU traffic environments is formulated as a binary hypothesis testing problem. Then, a test statistic for spectrum sensing is derived ...

User Selection Based Cooperative Spectrum Sensing for Cognitive Radio Networks

In cooperative spectrum sensing, information from several cognitive users is used for detection of the primary user. To reduce sensing overhead and total energy consumption, it is recommended that users with good performance be selected so as to optimize the probability of detection. One method of selecting the cognitive users with the best detection performance is proposed in this paper. It fo...
