Research On Key Technologies In Sensor Based Internet Of Things

In recent years,the rapid development of Internet of things,are widely used in environmental monitoring,industrial,agricultural,health care,smart city and other fields.The Internet of things senses the information about things around them through a lot of low power consumption,utility nodes,which are awareness,computing and wireless communication ability of micro sensor nodes.After data fusion and network transmission,the perception layer information is transferred to the application of the Internet of things,realizing the interconnection of all things.Therefore,the Internet of sensing things is the information base of the upper application,and the research of key technologies is also the hotspot of Internet of things research.This paper mainly focuses on the key technologies of the sensor based lot,investigate the research status of relevant technologies,and summarizes and analyzes the traditional algorithms.This paper mainly focuses on the analysis and algorithm improvement of perception-based tracking algorithm and routing technology of EH-WSN.The main contents and achievements are as follows:(1)Put forward the Target Tracking algorithm based on static triangle clustering(TCTT,Triangular Cluster based Target Tracking).The algorithm is based on the static trigonometric clustering,use grey prediction based on wavelet pretreatment to predict and the cluster structure activation mechanism is proposed.The simulation results show that the TCTT algorithm guarantees the high tracking accuracy and reduces the tracking delay and energy consumption.(2)For the intelligent family network environment,the indoor sensor tracking technology based on dynamic clustering is proposed.The algorithm uses dynamic cluster structure for tracking and wavelet grey prediction to predict the next position,dynamically activate cluster structure and ensure flexible and efficient indoor tracking.The simulation results show that the indoor sensing tracking technology based on dynamic clustering provides the accurate location information for network switching.(3)Analyze the characteristics and advantages of the energy harvesting sensor network(EH-WSN)and investigate the research status of the routing protocol of the energy harvesting sensor network.Based on the classical wireless sensor network Leach clustering algorithm,the evolution game clustering routing protocol for EH-WSN is proposed.Simulation results show that the cluster routing algorithm can balance network load and the network lifetime is extended.
