Abstract
Next-generation mobile communication networks promise the support for vast number of IoT devices with strong demand for spectrum access. The cater for the continuous growth of IoT applications, one of the challenges to mobile communication network providers is to allow dynamic spectrum access to a gigantic number of densely distributed and low-power IoT networks. In this paper, a novel dynamic spectrum access method is proposed based on spectrum trading for distributed IoT devices. The notion of access benefit is introduced which is based on the purchased band number and modulation mode provided to the mobile user. In the proposed solution, IoT users aim achieve optimization of their spectrum access by ensuring that the spectrum price will not exceed the access benefits from the spectrum trading by solving the spectrum optimization function. Due to the complexity of optimization objective function, pattern search algorithm is utilized to complete the final spectrum allocation optimization. Numerical results are also provided to testify the performances of the proposed spectrum optimization method.

Summary
As the critical part of 5G communications, Internet of Things (IoT) has attracting growing research attention from academia to industria in recent years [1]–[3]. Random and dense full duplex secondary users with sensing capabilities in distributed IoT environment was considered to dynamically use the idle spectrum. A novel dynamic spectrum access method is devised for distributed IoT environment with unsufficient authorized spectrum to be used. The main contribution of this paper is to address a market-driven dynamic spectrum access method in distributed IoT environments. In this overlay spectrum sharing scenario, the secondary IoT users are considered to pay the band fees and access authorized spectrum after estimating whether they can reap more benefits from this trading.
