Optical Fiber Based Sensor Internet of Things Throughput Maximization Relay Node Selection
The relay node is the transit center of the sensor Internet of Things communication,and the rationality of its selection is of great significance to ensure the stability of the Internet of Things communication and information throughput.A method of selecting relay nodes based on optical fiber to maximize the throughput of the sensing Internet of Things is proposed.The sensor Internet of Things model is constructed.The nodes are randomly arranged in the plane.All nodes are integrated using the point data.The main lobe is found in the target optical fiber sensor base station to identify the signal transmitted by the light source node.The average number of node energy is calculated,and the denominator of energy in the adaptive state is minimized.Among the candidate nodes,the relay node that can completely transmit the known optical channel status to other nodes is selected.Based on the statistical independent distribu-tion,the average received SNR of the system is obtained,and the fiber sensor antenna is selected to maximize the throughput.Simulation results show that the outage probability of the proposed method approaches 0 when the number of nodes is 22.When the power of the light source node is 30 dBm,the network throughput reaches 98％.
