Study on Sensor Network Spectrum Detection Technology based on Internet of Things

Abstract

Abstract-In this paper, we conduct theoretical analysis and numerical simulation on the sensor network spectrum detection technology based on Internet of Things. In the field of Internet of things, information service system as a means of information, intellectualized, is an important research direction. In structure, Internet information service system is mainly composed of persistent database. Wireless sensor network foot a composed of a set of information collection, processing, and wireless transmission in the integration of wireless self-organizing network composed of micro sensor nodes. Sensor nodes structure will be designed according to different application scenarios, the structure of the wireless sensor network node is used to describe the different periods and different types of sensor nodes. If the realization of cognitive radio technology in wireless sensor network, not only can alleviate the congestion of public frequency band, and reduce the work frequency of the wireless sensor network also makes the node after single jump coverage is wide and change.
