Verification Techniques Of WSN And Its Application In Smart Campus

With the popularization and development of wireless communication technology and the coverage of 3G/4G/WIFI networks,campus teachers and students hope to use mobile terminals to make full use of their own fragmentation time and obtain network information anytime and anywhere.The research on smart campus has become a hot topic in the current informatization.The construction of a smart campus maximizes the use of resources on campus,provides various services and information for campus teachers and students,and enhances the user experience through proactive services.This topic combines the WSN verification technology and the smart campus organically to provide a data exchange and knowledge sharing service platform for the campus.This topic combines the WSN verification technology with a smart campus to provide an intelligent,information-based innovation service for smart campuses,and promotes the integration of people and campus,people and information systems,campus entities and information systems,and strives for the common development of teachers and students.Integrated service platform.A series of research and exploration work was done for this purpose.First,based on the wireless sensor network ensure that data transmission is not stolen or tampered by illegal users.An optimized verification method is extended based on the merkle hash tree.This scheme is based on the partially materialize idea to optimize the merkle hash tree.Through some intermediate nodes can verify the integrity of the data.To a certain extent,it can make up for the shortage of traditional merkle hash tree,effectively verify the integrity of the data,reduce the data traffic and the verification time.Second,in order to solve the problem of multidimensional data verification,a multi-dimensional data range query protocol WQuery is proposed.This protocol protects the privacy of multi-dimensional data based on bucket mechanism and sequential encryption mechanism.And proposes a novel T2D data structure based on bucket mechanism.The scheme translates the actual query scope of user request into a matched set of bucket labels and verifies the integrity of the query results through the T2D data structure,and effectively improve the verification speed of multi-dimensional data.Thirdly,this topic combines the WSN verification technology with a smart campus.Through the requirements analysis,architecture design,function design,and database design,the service architecture is designed with the MVP programming concept.The service architecture of this project is composed of basic functions,curriculum,job release,WSN monitoring and camera monitoring and other functional modules.Based on the above research results,it provides important guiding significance and technical support for the construction of smart campuses.If in-depth research and promotion is possible,it will provide campus with an integrated,intelligent,all-round and mobile learning environment campus service.
