Research On Layered Network Technology Of Intelligent Spectrum Monitoring

In recent years,the radio spectrum monitoring platform has been developing towards the direction of information and systematization.In this process,many problems have been exposed,such as the poor flow of command and scheduling,the inconvenience of docking heterogeneous systems,and so on.Therefore,an improved scheme of spectrum monitoring system based on hierarchical networking architecture is proposed,and the load balancing scheme and message middleware technology suitable for the system are studied.It provides ideas for the integrated development of radio spectrum monitoring platform.In this paper,firstly,the original spectrum monitoring system are introduced briefly,and its shortcomings are pointed out.Therefore,the overall architecture and corresponding communication scheme of the hierarchical network monitoring system are designed.Then,the problems existing in the hierarchical network architecture are analyzed.It lays the groundwork for the later load balancing optimization scheme and the introduction of message middleware system.Then,a dynamic load balancing algorithm based on multi-task is proposed to solve the problem that the load of each service node is uneven in the process of processing many complex tasks in the computing server cluster in the monitoring system.In this algorithm,the task size is evaluated by the consumption of system resources by the task to be executed,and by considering the size of the task to be executed and forecasting the load status of the node,the task to be executed is assigned to the node with low average load variance.Thus,the load balance of the cluster is realized,and the efficiency of task execution is improved.Finally,in order to enhance the compatibility between the secondary monitoring system and other monitoring systems,and reduce the pressure of the monitoring server in the secondary monitoring system,a system architecture optimization scheme based on message middleware is proposed.The whole architecture and implementation scheme of the message server are designed,and the data transmission and scheduling mode in the system is optimized.The coupling degree between the monitoring system and other heterogeneous monitoring systems is reduced,at the same time,the load pressure of the secondary monitoring server is reduced,and the stability of the monitoring system is improved.
