An Efficient Switching Threshold-Based Scheduling Protocol for Multiuser Cognitive AF Relay Networks multiple primary receivers using orthogonal spectrums. Using orthogonal spectrum bands aims to mitigate the interference between users in wireless networks. The spectrum of primary receiver whose channel results in the best performance for the secondary system is shared with secondary users. To red

Implementing a MATLAB-Based Self-configurable Software Defined Radio Transceivering unprecedented levels of flexibility in parameter settings. However, programming and operating such SDRs have typically required deep knowledge of the operating environment and intricate tuning of existing code, which adds delay and overhead to the network design. In this work, we describe a bi-d

Opportunistic Energy Harvesting and Energy-Based Opportunistic Spectrum Access in Cognitive Radio Neenergy from nearby primary transmissions is investigated. Using an advanced RF energy harvester, a secondary user is assumed to be able to collect ambient primary RF energy as long as it lies inside the harvesting zone of an active primary transmitter (PT). A variable power (VP) transmission mode is

Channel Transition Monitoring Based Spectrum Sensing in Mobile Cognitive Radio Networks by the channel state. Mobility makes the problem of the traditional sensing mechanism more severe than in static scenarios. In this paper the channel transition monitoring based spectrum sensing mechanism is proposed. The proposed scheme not only reduces the influence of mobility on the current sen

Power Minimization Through Packet Retention in Cognitive Radio Sensor Networks Under Interference an of packets retention in a queue with the aim of minimizing transmission power in delay-tolerant applications. The problem is classified as an optimal stopping problem. The optimal stopping rule has been derived as well. Optimal number of released packets is determined in each round through an Integ
