With the increase of water storage capacity in the Three Gorges reservoir area,the self-purification capacity of water bodies is reduced,The water environment safety problem in the reservoir area has caused a wide range of domestic and international attention.At present,the existing monitoring equipment,methods and means can't meet the needs of the task,the urgent need to improve the Three Gorges reservoir water environment real-time online monitoring capabilities.The wireless sensor network has the advantages of low cost,flexible communication,good real-time performance,strong ability to deal with data,etc.,has been widely used in environmental monitoring and other fields.In order to obtain good monitoring effect,this paper presents a distributed cluster wireless sensor network architecture model and routing protocol for water environment monitoring in the Three Gorges reservoir area,and establishes the optimal cluster number of optimal energy consumption Algorithm and distributed cluster wireless sensor network routing protocol based on shortest path algorithm,Balance the energy consumption of nodes within the network,extending the entire network life cycle.The paper mainly includes the following contents:(1)In view of the Three Gorges reservoir area,there are meandering tree features with large area,wide distribution and irregular shape.Combined with the formation mechanism of water pollution in the river basin,a number of torch-shaped wireless sensor monitoring subnets were constructed with the focus of the torch-shaped diffusion areas along several coastal ports.And then build a distributed cluster wir eless sensor network architecture composed of several subnets.(2)In order to minimize the energy consumption of the torch-shaped wireless sensor to monitor the subnet,the optimal clustering energy consumption model is established by using the optimal clustering model,and an optimal cluster number algorithm based on energy efficiency is proposed.The number of nodes in the cluster is obtained,and the number of nodes in the cluster is well uniform,and the energy consumption is not balanced.The simulation results show that the algorithm can make the number of nodes in each cluster uniform,which avoids the emergence of large clusters and very small clusters,and reduces the energy consumption of the network.(3)According to the specific requirements of long-term,robustness and low cost of the water environment wireless monitoring network in the Three Gorges Reservoir area,the characteristics of the distributed cluster wireless sensor network based on the water environment monitoring in the Three Gorges reservoir area are combined.Based on the optimal cluster number algorithm,a distributed clustering WSN routing protocol based on the optimal cluster number and the shortest path algorithm is proposed according to the LEACH protocol and the Dijkstra algorithm.And the simulation and simulation of the routing protocol are carried out to verify the superiority of the routing protocol.
