An analytical evaluation of energy consumption in cooperative cognitive radio networks

This paper studies the total energy consumption of a cooperative cognitive radio network in coexistence with a stochastic multi-channel licensed network. Energy consumption of each cognition phase at the secondary user is mathematically analyzed and obtained. The numerical results presented show the various interactions between the secondary network size, availability of appropriate spectrum holes and the total energy consumption for different states of the cognitive radio network under discussion.
