In the vast territorial area of our country,the mountain environmental area accounts for about 33%,so the potential mountain environmental disasters pose a great threat to the daily production and life of the people.The traditional mountain monitoring method has the disadvantages of poor real-time performance,high cost and high power consumption.Therefore,it is of great significance to develop a monitoring system suitable for mountain environment.In view of the problems existing in the traditional wireless sensor network(Wireless Sensor Networks,WSN)monitoring methods,the research contents and results are as follows:Aiming at the common problems of traditional routing protocols in WSN data transmission,such as node energy consumption is too fast and death,network structure is unstable and so on.On the basis of traditional routing protocols and aiming at the characteristics of WSN in outdoor applications,this paper proposes an improved routing protocol algorithm suitable for outdoor applications,which is optimized by the idea of cluster head re-zoning and transmission path planning.The experimental results show that the algorithm can meet the requirements of reducing node energy consumption,improving the stability of network data transmission and prolonging the whole network cycle.In order to solve the problem of low positioning accuracy of the traditional received signal strength indication(Received Signal Strength Indication,RSSI)location algorithm,a chaotic particle swarm fusion RSSI centroid location algorithm is proposed.In this method,the distance between the sensor nodes is calculated by using RSSI ranging technology,and then the three anchor nodes and the located nodes closest to the unlocated nodes are selected to establish a mathematical model with the coordinates of unknown nodes as parameters.In the process of solving,based on the particle swarm optimization(Particle Swarm Optimization,PSO)algorithm,the chaos optimization idea is adopted,and the chicken swarm algorithm is used for further optimization.Simulation results show that,compared with the comparison algorithm,the new algorithm has a further improvement in positioning accuracy and performance,and increases its applicability in WSN applications.In view of the key issues that restrict the development of outdoor WSN,such as cost,stability,anti-interference,etc.,the traditional communication technology and dynamic encryption space dense cover ant colony(Dynamic crypto Dense cover Ant colony,DDA)technology in mountain environment monitoring The applicability and feasibility of thefollowing are discussed,and the new communication technology DDA is used as the construction of the entire system gateway and terminal.The test results show that the system functions normally and can complete the corresponding monitoring tasks.
