Research And Application On Coverage For Wireless Sensor Networks Base On AUV

With the development of industrial technology, the demand for resources is also increasing.Water has become the main theme of the world’s resources use. In order to effectively to thedevelopment and utilization of water resources, underwater wireless sensor network (UWSN) hasbecome a hotspot research of utilization of water resources. Among them, the research of wirelesssensor network （WSN）coverage control is necessary, how to improve the coverage efficiency,prolong the network’s life cycle has become the key problem in the research of the coveragecontrol.Around underwater wireless sensor network coverage control, this thesis analyzes and discussesthe existing coverage control problem, and puts forward a mobile node based on regular hexagonalcells is introduced the control method. The method first to divide the grid on target area, then insertthe mobile sensor2-coverage of target area. This method improves the quality of the underwaterwireless sensor network coverage and save the energy of sensor nodes, so as to prolong the networklifetime. In addition, though the simulation analysis, we prove such method can decrease moreenergy consumption than others to prove effectiveness.Finally, this thesis designs and implements the prototype system of water environmentalmonitoring. Introduced the measuring temperature monitoring node of internal structure and thedesign of hardware, the writing of the monitoring node software design and function, design andbackground server system is established, and the proposed node deployment method into the systemin this paper. This system verifies the effectiveness on such system and feasibility through operatesin actual environment.
