Abstract EN
Energy resource management is a crucial problem of a device with a finite capacity battery.
In this paper, cognitive radio is considered to be a device with an energy harvester that can harvest energyfrom a non-RF energy resource while performing other actions of cognitive radio.
Harvested energy will be stored in a finite capacity battery.
At the start of the time slot of cognitive radio, the radio needs to determine if it should remain silent or carry out spectrum sensing based on the idle probability of the primary user and the remaining energy in order to maximize the throughput of the cognitive radio system.
In addition, optimal sensing energy and adaptive transmission power control are also investigated in this paper to effectively utilize the limited energy of cognitive radio.
Finding an optimal approach is formulated as a partially observable Markov decision process.
The simulation results show that the proposed optimal decision scheme outperforms the myopic scheme in which current throughputis only considered when making a decision.
