Energy consumption analysis in link adaptive cognitive radio network
Rajarshi Mahapatra · 2009
In this paper, we investigate the energy consumption of a wireless cognitive radio (CR) network, where each node is equipped with CR and the network is an OFDMA system operating on time slots. In particular, we investigate the energy consumption efficiency in CR network using a joint adaptive modulation and power allocation algorithm. We also investigate the optimum network area for green communication.
