Research And Implement For Web Notification Service Based On SWE

Currently, there is a wide range of sensor networks. Due to the lack of interoperability of the sensor networks, specific sensor network can only be accessed by specific applications which have caused a serious waste of resources. Service-oriented software architecture has resolved the problem of interaction amony heterogeneous. Web Notification Service provides services which can be called by any sensor network users via the Internet to obtain the sensor network node observation information. The main purpose of this thesis is to design an open architecture through stduying on the network based on Web Notifacation Sercices of SWE, and design and implement the network notification service prototype system.This thesis first systematically expalins the theory about SWE network notification service, including the SWE architecture, network notice services transaction processing and core operations, and gives a brief description of the current situation.Second, this thesis detailes the network notice of service of the prototype system design process, and proposes an open layered network notification service architecture which combined the service-oriented thinking. This thesis gives the designing of presentation layer, business logic layer, data access layer repectively which aim to meet the functional requirements of the prototype system. The other technologies were deployey in the prototype system including the registration mechanism.The thesis research and solve the registration system, Web filtering technology, packaging technology of XML information and notices information dissemination and other key technologies; then research and design WNS interface between use,SPS, and the database. All of these studies was used in the prototype system.The last section of this thesis focuses on the core business processing to achieve the network notification service prototype system, which includes the implementation of the registration business processes, accessing to the business processes. Then this thesis gives the competition of the three mainly operates of WNS. In the designing of business logic layer, this thesis uses the hierarchy relationship of the classes and the implement method while completing the data operating via technology of database connection pool and factory class in the data access layer. Finally, this thesis deploys the prototype system into infrared Building Monitoring System., and tests the Web Notice Service, check the core operates, complete the function of the Web Notice Service.
