In this paper, the green communication for the fifth generation Internet of Things base on the energy storage and security issues is investigated. Since the optimization problem is nonconvex, an iteration optimization algorithm is designed to divide the objective optimization task into two subproblems, namely, a joint transmitter and PS factor optimization subproblem and a minimum mean-square error-based receiving filter optimization subproblem, as the optimization task is a nonconvex function.

The proliferation of heterogeneous gadgets connected by large-scale networks is a clear sign that the Internet of Things' vision is getting closer to becoming a reality. Many researchers and experts in the field agree that the next-generation cellular platforms will be a major boost to the IoT deployment. We thoroughly discuss the added-value benefits introduced by cell/noncellular D2D communications and its potential in effectively meeting IoT requirements in 5G networks in this paper.

A wide variety of high-quality services and unfaltering user experiences are expected to be available in a near future. Considered above, we take a step forward in this paper by announcing a dedicated SDN-based integrated defense framework for the Internet of Radio Light system that is based on 5G architecture design. The enclosed experimental findings show that the proposed security framework is both effective and cost-effective, and therefore can be considered as a promising defensive solution.

We investigate the connection mechanism and interaction method between the cloud service system layer and the mobile terminal service layer and the mobile terminal service layer, as well as the associated application layout. This issue mainly examines the cloud service system's information exchange mechanism and production control mechanism from the perspective of the system's intelligent design This paper appears in this paper, mainly because of the information exchange mechanism and production control mechanism. A modular production implementation scheme is developed based on the hardware of the manufacturing system layer and is intended to make it the basis for the development of the system's automated manufacturing. The cloud service system's massive data processing capabilities, the information processing module, and the production decision-making mechanism have been developed for it, in order to enable the intelligent modification of the manufacturing system layer in the production process. The primary goal of network optimization, based on the use of NB-IoT technology in the next-generation mobile communication network, is to ensure the random access of IoT devices as much as possible. We develop a mathematical model based on the connection scenario of the Io T group paging model and then use the mathematical formula to determine the number of IoT devices distributed to each time slot in the first state, thereby deriving the precise time slot scattering algorithm.

Indoor positioning based on a 5G system has piqued interest. A fingerprinting scheme for indoor positioning based on a 5G system has attracted interest. To minimize the noise of Received Signal Strength values, the Kalman filter is used as preprocessing of raw data. Both indoor scenarios are considered, whether the base station is located in the same room with user equipment or not. The predicted KF and UK algorithms achieve 53% positioning accuracy increase in test room A.
