[Abstract]:The IoT sensor network is widely used in the field of environmental monitoring and pattern recognition. The routing protocol of the IOT sensor network is constructed by multi-hop convergence tree routing network. With the increase of the number of nodes, link failure is easy to occur. This paper presents an improved routing design method for sensor networks in the Internet of things based on chain header extraction and information source location. A network and routing detection model for sensor networks under the Internet of things is constructed. Link information cluster head node extraction and information source location are used for link routing information data aggregation, preweighting method is used to broadcast the energy loss of cluster head node, and bidirectional link estimation is used to obtain the data transmission protocol of the routing node. The routing optimization design is realized by using link node energy and Sink node distance stratification method. The simulation results show that this method is used to optimize the routing design of the IoT sensor network. The reliability and throughput of link information transmission and transceiver are improved, and the performance is superior.
