Abstract This paper investigates the power control and routing problem in the
communication process of an energy harvesting (EH) multi-hop cognitive radio network
(CRN). The secondary user (SU) nodes (i.e., source node and relay nodes) harvest energy
from the environment and use the energy exclusively for transmitting data. The SU nodes
(i.e., relay nodes) on the path, store and forward the received data to the destination node.
We consider a real world scenario where the EH-SU node has only local causal
knowledge, i.e., at any time, each EH-SU node only has knowledge of its own EH
process, channel state and currently… More >
