Outage Probability Minimization for Energy Harvesting Cognitive Radio Sensor Networks
The incorporation of cognitive radio (CR) capability in wireless sensor networks yields a promising network paradigm known as CR sensor networks (CRSNs), which is able to provide spectrum efficient data communication. However, due to the high energy consumption results from spectrum sensing, as well as subsequent data transmission, the energy supply for the conventional sensor nodes powered by ...
متن کاملThroughput maximization in electromagnetic energy harvesting cognitive radio sensor networks
In the near future, billions of wireless devices are expected to be operational. To enable the required machine to machine communications, two major problems must be addressed. How to obtain the required spectrum efficiency, and how to deliver the required power to these devices. The most promising answers to these questions are cognitive radio and energy harvesting, respectively. Energy harves...
متن کاملOutage Probability Analysis for Asynchronous Cognitive Radio Networks
In this paper, we consider a primary network coexisting with a secondary network in a spectrum sharing asynchronous cognitive radio (CR) network. We analyze the outage probability of the secondary network under the maximum power constraint and interference constraint. The validity of the analysis is verified by computer simulations.

متن کاملAnalysis of the Packet Loss Probability in Energy Harvesting Cognitive Radio Networks
A Markovian battery model is proposed to provide the variation of energy states for energy harvesting (EH) secondary users (SUs) in the EH cognitive radio network (CRN). Based on the proposed battery model, we derive the packet loss probability in the EH SUs due to sensing inaccuracy and energy outage. With the proposed analysis, the packet loss probability can easily be predicted and utilized ...
