We consider an energy harvesting wireless communication link, where arriving data packets have different importance values. The wireless transmitter needs to decide whether each arriving data packet should be transmitted or not, based on the packet's importance value, channel condition, and energy status. Under certain conditions, we show this high dimensional control problem can be transformed to...
We consider a single channel energy harvesting cognitive radio system, where the joint optimization of spectrum sensing, channel probing and transmission power control is considered with the goal to maximize the throughput. We model this control problem as a two-stage continuous-state Markov decision process with one stage for sensing and probing control, and the other for transmission power control...
In this paper we propose an energy harvesting-based cooperative jamming and full-duplex relaying scheme to enhance the secrecy rate for wireless communication between a source node and a destination node, in the presence of an eavesdropper. To characterize the performance, we develop a mathematical analysis framework for instantaneous and average secrecy rates. We consider the practical interference...
We consider a wireless energy harvesting (EH) relay network. Relays without embedded energy supply harvest energy from the source node. Considering a time switching protocol, performance measures such as average signal-to-noise ratio (SNR), outage and throughput are analyzed. Subsequently, optimal EH time is selected in order to maximize the throughput. Then, a multiple-relay network is considered...
