Data Acquisition And Sharing System Based On Small-world Network

The continuous development of modern science and technology promotes whole society to step into the information age quickly,and the applicationscope of network information technology is more and more extensive.Paperlessoffice,Personal Entertainment,interpersonal communication are inseparable from the network technology.The development of intelligent terminal makes the applicat-ion of network more flexible and extensive,the upgrade of network equipment makes the information transmission ability increase quickly.Accord-ing to the difference of transmission medium,we divide communication network into wired and wireless.Wireless network is playing an increasingly important role due to its flexibility and simplicity.But in practical application,wireless network isr estricted by terrain,base station and other conditions,in the spe-cial application environment such as mine exploration and investigation,the signal coverage and transmission ability of wireless network have been gre-atly affected.There is a lack of contact among the units,the collected data and information can not be collected and shared until the conditions of network equipment permit.The soft-ware that can realize the similar function is also based on the application of Internet.Small-world network software for individual application environment is rare,and these softwaries facing a large customer base,so its server cost,network construction costs areextremely high,and not flexible enough to use.In order to realize the function of real-time data sharing and instant communication among multiple users in the environment of poor network coverage,a data acquisition and sharing system based on small-world network is developed.The system uses C/S architecture,java language in Eclipse and AndroidSt-udio project platform for programming.Using HTTP to realize communication,using MySQL database to store and verify user information,thus realizing self-organization of WLAN in many application scenarios.In WLAN,all clients can upload the file data into local memory to the server,and server will store the received data in the corresponding device.The data resources in the server can be downloaded and shared by other clients at any time,meanwhile,client can choose the communication object to realize the instant communication.In the development process,through the practical application value analysis,the overall scheme design,each module programming,the system test analysis,finally realize the anticipated goals.The system for data acquisi-tion and sharing in WLAN is developed.The system has the following advantages:No need to use the Internet,only using routers to build a small local area network,that is to say,it is simpleand flexible;The server can be built directly using a personal computer,the client can use a hand-held mobile device,low Cost;Data transmission without Internet,reduce the risk of network attacks,data theft,information security has improved;Code open source,reserved development interface,according to post-functional needs to be updated;in addition to the network signal blind area use,real-time file sharing can also be used in daily classes and meetings.
