Abstract:
In wireless powered cognitive radio network (CRN), a cognitive radio user (CU) can receive the wireless power transferred from an energy source for its operation. In this paper, we consider the operations of a CU in the CNR with wireless powered transfer. The operations of the CU include three modes in terms of data transmission (DT), receive wireless power (WP) and sleep (SL). In order to consider the effect of the future operation on the current reward of the CU, we formulate the problem to choose an optimal operation mode of the CU as a partially observable Markov decision process (POMDP), in which the two states in terms of belief about the channel state and remaining energy are utilized as main factors to determine an optimal operation of the CU. Simulation results prove the efficiency of the proposed scheme.
