Research On Radio Resource Allocation Algorithm In Future Mobile Social Networks

With the promotion of technology such as Internet,computer and Internet of things,people's lives have changed a lot.The business requirements of people in communication have changed from single voice service and video service to ultra-high data transmission rate,zero delay user experience,massive equipment connection and so on.Although the 4G network has entered the stage of mature application,there are still many difficulties to support the needs of mobile users for all kinds of business.Therefore,the fifth-generation mobile communication has become a global research hotspot.So,in the condition of limited spectrum resources,how to maximize the user's various business needs and improve the utilization of radio resources has always been a research hotspot.In the fifth-generation mobile communication,the problem of how to allocate radio resources effectively and improve the utilization ratio is worthier of study.Therefore,this paper mainly analyzes and studies the allocation algorithm of radio resource,and the relevant contents are as follows:Firstly,this paper introduces and analyzes the network architecture of future mobile social networks,the key technologies,the application scenarios and the research of radio resource management.Secondly,due to the fact that the main consideration is single ratio resource allocation in previous research work,the allocation of confidential resources in the process of radio resource allocation is neglected,and resources' security and confidentiality can't be guaranteed.Therefore,in the study of the resource allocation in mobile social networks,this paper makes a joint consideration of radio resources and confidential resources.Meanwhile,based on gradient iteration,a resource allocation algorithm is proposed in this paper.The simulation results show that,compared with the random allocation scheme,the algorithm has a certain effectiveness in improving the user's radio resources and the energy efficiency of confidential resources,and also improves the energy efficiency of the system.Finally,this paper analyzes and studies the radio resource allocation in the "Femto cell" network and establishes the three-order system model based on Stackelberg game theory.In addition,according to the effective capacity,we set up the energy efficiency utility function of the "Femto cell" base station and propose a power allocation algorithm based on gradient assistance is to allocate power for the "Femto cell" base station.Through the simulation of MATLAB,we find that the algorithm proposed in this paper can effectively improve the energy efficiency of spectrum resources and is superior to existing algorithms to a certain extent.
