Research On IMS Virtualized Architecture And VANET Resource Allocation Algorithm

With the development of society and the advancement of technology,the number of vehicles has increased sharply,and the IoV is considered to be an important solution for optimizing traffic efficiency,reducing traffic accidents,and improving driving experience.Although different vehicle manufacturers provide personalized service functions according to the individual needs of current users,there is no unified telematics business architecture to meet the scalability and flexibility of different current businesses.In practice,the IP Multimedia Subsystem(IMS)as a core network architecture is very mature.It plays a huge role in signaling control and resource management.It can play a role in terminal equipment in a variety of access networks.Manage and provide multimedia applications services to meet the diverse needs.In the 5G scenario,the significant improvement in communication capabilities has brought great advantages to the rapid development of the IoV.Various business services and applications have emerged,which has also brought huge technical challenges to the management of the IoV.The main work of this paper is based on the research of the IP multimedia subsystem architecture and the IoV business.It is oriented to the future 5G communication technology,virtualizes and improves the IMS network architecture,and provides various data information services more efficiently.The current IMS architecture has problems such as high cost of special equipment operation and maintenance,poor flexible deployment,and low utilization efficiency.By introducing virtualization technology,the IMS service architecture system will adopt a layered model,control plane network elements will be dynamically and flexibly deployed,the data plane network elements remain unchanged.On the premise of improving data management capabilities and improving the flexibility of the architecture,it can also ensure the reliability of the architecture data.In the process of virtualization deployment,how to allocate resources is an important challenge.This paper will consider the problem of resource allocation under the IMS virtual architecture,comprehensively consider the network environment,and optimize computing resources and link resources.The Hidden Markov Model mathematically models the network,and then optimizes the algorithm to complete the selection of VNFs based on user needs and solves the problem of reasonable deployment and allocation of resources.Finally,the open source platform simulation is used to compare and analyze the reliability of the virtualized IMS architecture and the performance of the resource allocation algorithm.
