Cognitive radio (CR) is fast emerging as a promisingudtechnology that can meet the machine-to machine (M2M)udcommunication requirements for spectrum utilization and powerudcontrol for large number of machines/devices expected to beudconnected to the Internet-of Things (IoT). Power control in CR as audsecondary user can been modelled as a non-cooperative game costudfunction to quantify and reduce its effects of interference whileudoccupying the same spectrum as primary user without adverselyudaffecting the required quality of service (QoS) in the network. In thisudpaper a power loss exponent that factors in diverse operatingudenvironments for IoT is employed in the non-cooperative game costudfunction to quantify the required power of transmission in theudnetwork. The approach would enable various CRs to transmit withudlesser power thereby saving battery consumption or increasing theudnumber of secondary users thereby optimizing the network resourcesudefficiently.
