Publikováno v: IEEE Transactions on Vehicular Technology

Cognitive radios enable dynamic spectrum access where secondary users (SUs) are allowed to operate on the licensed spectrum bands on an opportunistic noninterference basis. Cooperation among the SUs for spectrum sensing is essential for environments

Cognitive radio networks present challenges at many levels of design, including configuration, control, and cross-layer optimization. To meet requirements of bandwidth, flexibility and reconfigurability, systematic methods to model and analyze cognit

On the Security of Key-Based Interval Splitting Arithmetic Coding With Respect to Message Indistinguishability

Autor: R.S. Katti, Aida Vosoughi

Publikováno v: IEEE Transactions on Information Forensics and Security. 7:895-903

Key-based interval splitting arithmetic coding (KSAC) has been proposed to improve the security of traditional arithmetic coding (AC). Chosen-plaintext attacks have been proposed for KSAC when the same key is used to encrypt different messages. In th

In this paper, we investigate the decoding performance of spatially-coupled LDPC codes in the case of faulty-memory bit-cells within the storage modules of the decoder.Our study characterizes error resilience, by measuring the BER degradation from su

A cooperative spectrum sensing scheme for cognitive radio ad hoc networks based on gossip and trust

Autor: Joseph R. Cavallaro, Alan G. Marshall, Aida Vosoughi

Publikováno v: GlobalSIP

In a cognitive radio ad hoc network, secondary users must cooperate in a decentralized way in order to determine the presence or absence of the primary user. In such a setting, malicious nodes deteriorate the cooperative spectrum sensing performance
