Outage Performance of Cooperative Cognitive Radio Networks under Joint Constraints of Co-Channel Interference, Intercept Probability and Hardware Imperfection [PDF]

open access: yesEAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2019
This paper evaluates outage probability (OP) of a cooperative underlay cognitive radio network in the presence of a passive secondary eavesdropper under joint impacts of limited interference from a primary network and hardware impairments. With intercept

Cooperative transport with selective kinetic constraints [PDF]

open access: yesPhysical Review E, 2019
We introduce and study a family of cooperative exclusion processes whose microscopic dynamics is governed by selective kinetic constraints. They display, in sharp contrast to the simple symmetric exclusion process, density profiles that can be concave, convex or both, depending on the density of boundary particle reservoirs. A mean-field analysis based

Cooperative Spectrum Sensing Schemes with the Interference Constraint in Cognitive Radio Networks

open access: yesSensors, 2014
In this paper, we propose cooperative spectrum sensing schemes, called decode-and-forward cooperative spectrum sensing (DF-CSS) scheme and amplify-and-forward cooperative spectrum sensing (AF-CSS) scheme, in cognitive radio networks.

Optimal Power Management to Minimize SER in Amplify and-Forward Relay Networks [PDF]

open access: yesAUT Journal of Electrical Engineering, 2018
This paper studies optimal power allocation to minimize symbol error rate (SER) of amplify-and-forward cooperative diversity networks. First, we analytically solve optimal power allocation problem to minimize SER for three different scenarios, namely ...

Cross-Layer Optimization Scheme Using Cooperative Diversity for Reliable Data Transfer in Wireless Sensor Networks

open access: yesInternational Journal of Distributed Sensor Networks, 2014
Cooperative diversity has been shown to provide significant performance gains in wireless networks where communication is impeded by channel fading. In resource constraint networks, the advantages of cooperation can be further exploited by optimally ...

Simultaneous Wireless Power Transfer and Secure Multicasting in Cooperative Decode-and-Forward Relay Networks

open access: yesSensors, 2017
In this paper, we investigate simultaneous wireless power transfer and secure multicasting via cooperative decode-and-forward (DF) relays in the presence of multiple energy receivers and eavesdroppers.

Satisfaction-Based Energy Allocation with Energy Constraint Applying Cooperative Game Theory

open access: yesEnergies, 2021
There has been an effort for a few decades to keep energy consumption at a minimum or at least within a low-level range. This effort is more meaningful and complex by including a customer’s satisfaction variable to ensure that customers can achieve the ...

Constraints on evolutionary shifts in cooperative breeding [PDF]

open access: yesBehavioural Processes, 2007
Bergmuller et al. (2007) provide an insightful review of four ey issues surrounding the evolution and maintenance of cooprative breeding, and suggest how these can be integrated into single hierarchical classification of mechanisms maintaining ooperative behaviour. I agree that this integrative approach ay be useful in creating a unified framework that

Integrated Guidance and Control of Multiple Interceptors with Impact Angle Constraints Considered

open access: yesXibei Gongye Daxue Xuebao, 2019
To solve the multi-interceptor coordination problem and to intercept the target with impact angle constraint, a novel distributed cooperative control algorithm with impact angle constraint based on integrated guidance and control is proposed.

Collaborative Task Assignment for Multi-UAV with Sequence and Time Constrains [PDF]

open access: yesXibei Gongye Daxue Xuebao, 2018
In this paper, based on task sequence and time constraint in the SEAD mission of multi-UAV, a heterogeneous multi-UAV cooperative task assignment mathematical model is established. We put forward a hybrid algorithm GSA-GA(gravity search algorithm-genetic
