We consider the time-unslotted cognitive radio based dynamic spectrum access (DSA) networks, where the secondary users (SUs) are unsynchronized with the primary users (PUs). We analytically derive the tradeoff between the energy consumption for spectrum sensing and the spectrum opportunity for SUs in terms of available spectrum usage… (More)
