Research On CSE Collaboration Optimization Based On OneM2M

The Internet of Things(IoT),as an extension of the Internet,has a variety of technological innovations and breakthroughs,among which protocol is the key point of the IoT technology and plays a role in achieving interconnection between IoT devices.As an important protocol in the field of Internet of Things,oneM2M not only formulates the connection specification of devices,but also formulates the standards for security and management in the application environment.Based on the oneM2M protocol,this thesis studies the collaborative optimization of CSE functions.The main work is as follows:1.Investigated and analyzed the oneM2M protocol,NB-IoT protocol and architecture optimization techniques.The structure of oneM2M protocol and the relationship between core CSE functions are analyzed.The system architecture of NB-IoT protocol is analyzed.Traditional architecture optimization techniques are also analyzed.2.According to the characteristics of big data and high concurrency in the real Internet of Things scenario,the optimization scheme of CSE in oneM2M architecture is proposed,which mainly includes two parts:data management and database optimization,communication management optimization.The optimization effect is verified by simulation test.Through CSE optimization.The CSE optimization scheme improves the performance of oneM2M architecture in the real Internet of things scenarios.3.Designed and implemented the general method of multi-protocol transformation based on oneM2M.Based on the analysis of Internet of Things protocols such as oneM2M,the protocol transformation under different scenarios is classified and studied.A general scheme for multi-protocol transformation is proposed.A scheme for NB-IoT device access to oneM2M platform is designed and implemented on the basis of the general scheme.Besides,an access flow optimization scheme is proposed.Through the simulation test,the connectivity of the access scheme and the optimization effect of the access optimization scheme are verified.The architecture optimization scheme and protocol transformation scheme proposed in this thesis have both versatility and feasibility,which can provide reference for the implementation and interaction and collaboration of subsequent IoT protocols.
