Effective Optimization Criteria and Relay Selection Algorithms for Physical-Layer Security in Multiple-Antenna Relay Networks
Physical-layer security for wireless networks has become an effective approach and recently drawn significant attention in the literature. In particular, the deployment and allocation of resources such as relays to assist the transmission have gained significant interest due to their ability to improve the secrecy rate of wireless networks. In this work, we examine relay selection criteria with...
متن کاملPerformance Analysis of Relay Subset Selection for Amplify-and-Forward Cognitive Relay Networks
Cooperative communication is regarded as a key technology in wireless networks, including cognitive radio networks (CRNs), which increases the diversity order of the signal to combat the unfavorable effects of the fading channels, by allowing distributed terminals to collaborate through sophisticated signal processing. Underlay CRNs have strict interference constraints towards the secondary use...
متن کاملPrioritization, security and relay selection in network coded multiple access relay networks
Wireless communication is undoubtedly one of the most significant advancements by the mankind for improving quality of life. Information is transmitted from one point to another via electromagnetic waves. After Shannon’s landmark paper “A Mathematical Theory of Communication” in 1948, significant advancements have occurred in providing reliable point to point wireless communication. With ever g...
متن کاملRelay Selection and Resource Allocation in LTE-Advanced Cognitive Relay Networks
In this work, we consider the problem of joint relay selection and resource allocation in Long Term Evolution-Advanced (LTE-A) systems which provides both cognitive radio and relaying scheme capabilities. We assume that the total network is deployed in an overlay scheme where the primary user communicates via a relay assisted LTE-A network, some of the secondary users play the relaying role and...
متن کاملRelay Selection and Resource Allocation in One-Way and Two-Way Cognitive Relay Networks
Relay Selection and Resource Allocation in One-Way and Two-Way Cognitive Relay Networks Ahmad Mustafa Alsharoa In this work, the problem of relay selection and resource power allocation in oneway and two-way cognitive relay networks using half duplex channels with di↵erent relaying protocols is investigated. Optimization problems for both single and multiple relay selection that maximize the su...
