The Resource Management Methods In Heterogeneous Wireless Networks

The development of 5G and various communication services has greatly promoted evolution of heterogeneous wireless networks.In the future,the growth of large-scale users increase the amount of service data in the network,which further increase the pressure of network resource management.Optimizing the utilization efficiency of network resources and increasing the on-demand allocation of network resources are the problems that need to be solved in the future heterogeneous wireless networks.Making full use of diversified information from mass users also brings opportunities to propose effective network resource management schemes.Therefore,a new resource management problem that meets the new generation of heterogeneous wireless networks has become a key issue that needs to be resolved.Firstly,it reviews the related theories of heterogeneous wireless networks and network resource management.This paper summarizes the development trends and technical foundations of heterogeneous wireless networks and introduces a layered model of future heterogeneous wireless network architecture.At the same time,the theoretical basis,technical principles and performance indicators of some basic models of network resource management are described.Secondly,a multi-channel network coding resource management algorithm based on data content is proposed for heterogeneous wireless network architecture.In this paper,data fusion method is used to cluster the data transmitted in the network according to the D-S evidence theory,so that the devices in the network can be reasonably divided.Based on clustering of network devices,a channel allocation algorithm is designed in this paper.According to the number of device clusters,the channels are scheduled and allocated,and the channel resources and the network clusters are taken into account to balance the channel resources in heterogeneous networks.The network coding is employed in the transmission process to improve the transmission quality,based on which improve the transmission throughput.Simulation experiments show that the proposed scheme can effectively improve the network throughput and reduce the network transmission cost.So it can achieve the balance between resource allocation efficiency and network performance.Finally,this paper introduces the algorithm of virtualized network resource management based on data correlation.In this paper,a network resource management mechanism based on virtual cell is designed by device information,network resources and other abstract information.In the process of data correlation,the CCA is obtained by typical correlation analysis.According to the data content,the clustering model of the heterogeneous devices is produced.The construction of the virtual cell which centralized by user is realized.The opportunity for cooperation and sharing is provided for data transmission,and the computing elimination in the network transmission process is reduced.Then,a virtual network resource management mechanism centered on user device is designed to handle the problem of the spectrum resources of heterogeneous wireless networks and the power of the system.The convex optimization is employed to solve optimal resource allocation.The virtual cell construction method and resource allocation method are designed to optimize the system energy and improve the utilization of network resources.
