In order to utilize atmospheric water resources efficiently to alleviate the problem of water shortage in China,Huazhong University of Science and Technology has carried out related theoretical and experimental research on artificial precipitation technology based on charged particle catalysis.In order to monitor and evaluate the experimental effect during the artificial rainfall and snow experiment,it is necessary to research the wireless sensor network technology for meteorological and hydrological monitoring in the experimental area.Based on the actual needs of deploying wireless sensor networks in the field,this paper proposes a self-organizing wireless sensor network system based on energy efficiency optimization strategies.First,the software and hardware architecture of the wireless sensor network system is given based on the idea of software-defined network.Based on this,an event-based wireless sensor network control protocol named CFET Device protocol was designed.The task processing mechanism of the gateway and data nodes,the autonomous access mechanism of the sensing network based on the registration mode,and the system's sensing data collection model are proposed.Subsequently,the software and hardware implementation schemes of the gateway and data nodes are given.Next,the energy efficiency optimization scheme of the wireless sensor network was described in detail.From the perspective of energy saving of a single sensor node and the overall energy balance of the network,the sleep scheduling mechanism of the sensor nodes and the dynamic routing permission management mechanism of the sensor network were designed and implemented.At last,functions of the proposed system is tested by actual experiments,and the energy-saving performance of the system is simulated.It verifies the feasibility of the scheme described in this article,and also proves that the system has excellent energy-saving performance.The self-organizing wireless sensor network system based on energy efficiency optimization strategy proposed in this paper effectively solves the problem of real-time acquisition of sensing data in the monitoring area,and introduces energy efficiency optimization strategies suitable for wireless networks based on the realization of the sensor node self-organizing access system.It improves the energy efficiency of wireless sensor networks greatly and extends the life cycle of the system.
