Abstract
Owing to the limited energy-storage capacity of a nanosensor in electromagnetic wireless nanosensor networks (EM-WNSNs), energy efficiency has become an issue in EM-WNSNs. In this study, a non-cooperative power control game (NPCG) is applied to EM-WNSNs for the emission power control of nanosensors, its use generates energy savings. First, a system model is established based on the terahertz channel properties. Second, an NPCG for EM-WNSNs is presented, along with a novel utility function, Nash equilibrium (NE) and its existence and uniqueness, and a power control algorithm based on game theory. Third, the point-to-point communication between nanosensors and a nanocontroller is simulated. Simulation results show that the NE of the NPCG is constrained by the profit and cost parameters of the utility function.
