| With the development of electric power Internet of Things and the increase of the number of transmission pipeline corridors,the monitoring demand of transmission pipeline corridors has become more and more urgent,and there is an urgent need for low-cost and efficient digital operation and maintenance methods to support pipeline monitoring.Wireless AD hoc network is a low cost network,which is also the most economical and feasible network covering the pipeline corridor.Meanwhile,LoRa has become the best choice for deploying wireless AD hoc network in the transmission pipeline corridor due to its easy deployment and openness.However,due to the special environment of the transmission pipeline corridor and the lack of power supply,relevant studies need to be carried out to improve the balance of the network and improve the distribution of network services.This reduces service transmission delay and network power consumption and prolongs network service life.Starting from the narrow and long scene features of the transmission pipeline corridor,this paper deeply analyzes the technical indicators and communication requirements of the transmission pipeline corridor monitoring business in view of the routing optimization problem of LoRa wireless AD hoc network,and studies the balanced routing optimization of the transmission pipeline corridor in LoRa wireless AD hoc network,constructs the optimization model and proposes the model solution method.The main work includes:(1)Research on load balancing routing optimization of LoRa wireless AD hoc network in transmission pipeline corridor.Based on the analysis of the necessity of load balancing routing optimization in LoRa wireless AD hoc network,the basic idea of load balancing routing optimization was proposed,the load balancing optimization model was constructed,and the optimization implementation method was proposed.The effectiveness of the proposed method was proved by simulation experiments.(2)Research on energy balance routing optimization of LoRa wireless AD hoc network for transmission pipeline corridor.Based on the analysis of the necessity of energy balance routing optimization in LoRa wireless AD hoc network,the basic idea of energy balance routing optimization was proposed,the energy balance optimization model was constructed,and the optimization implementation method was proposed.The effectiveness of the proposed method was proved by simulation experiments.The route optimization method proposed in this paper can effectively improve the balance of network,improve the distribution of network traffic,and thus extend the network life time. |
