According to recent research published in the journal IEEE Transactions on Wireless Communications, "In this paper, energy efficient spectrum access is considered for a wireless cognitive radio ad hoe network, where each node is equipped with cognitive radio, has limited energy, and the network is an OFDMA system operating on time slots. In each slot, the users with new traffic demand will sense the spectrum and locate the available subcarrier set."
"Given the data rate requirement and maximal power limit, a constrained optimization problem is formulated for each individual user to minimize the energy consumption per bit over all selected subcarriers, while avoid ...
