Abstract: In order to improve the efficiency of data storage and query in wireless sensor networks,minimize the energy consumption of the network and extend the life cycle of a network to work simultaneously,an energy-efficient wireless sensor network data storage and query mechanism based on the virtual ring was proposed.Sensor network domain will be divided into many virtual ring network,then the collection ring is defined by a function of the value of the cost based on minimum network energy consumption,and the storage and query tasks of event data are executed through collection ring.The simulation results show that compared with other energy-saving programs and data storage solutions,the proposed SDS obtains better results in the extension of the network life cycle and the improvement of energy efficiency.
