Dynamic Power Allocation for Nano-Communication Networks in the Terahertz Band

초록

Nano-communication networks operating in the Terahertz band are developing fast owing to the high bandwidth range. In this paper, we propose a dynamic power allocation scheme for data transmission in the nano-communication networks. Based on the time-varying energy resource of nano-node for the network, we develop a stochastic optimization model to maximize the average channel capacity. The problem of stochastic optimization is solved via the Lyapunov optimization theory, and a novel capacity-optimal power allocation (CoPA) algorithm is proposed to accommodate the nano-communication network only according to the current energy resource information of nanonodes. Simulation results validate the theoretical analysis of our proposed scheme
