Design And Implementation Of Extended Network Communication Middleware For Mobile Devices

As the mobile Internet developing rapidly, many platforms and related technologies are brought to us. They’ve played a significant role in helping the development of mobile internet, while they also brought some problems in the development and design procedure. Firstly, mobile internet is not as open as the former custom internet:data between apps are blocked and cannot be used by other apps or search engine freely. Secondly, personal data from app users are much more vulnerable under the wireless network environment, they are more likely to be get by third part listener. Last but as the same important, basic framework is seriously needed to build up safe, open and efficient app, but up to now this thing is still just imagination.A brand new mobile extend internet middleware is introduced, trying to solve these difficult problems. Based on certain platform, the middleware provide unified service interfaces, such as to solve inter-platform concerned questions. The middleware can be divided into three parts based on the services they provide. RESTful web service module provide open web service. A detailed and formal design procedure is introduced to build this kind of web service, making sure that the latter is open and transplantable. Safe communication module provide safe and encrypted communication solution and resource management and synchronization module provide efficient resource using and loading scheme through using multiple layers cache system and offline resource synchronization algorithm. All these modules can be get together to make a complete middleware by using the term URI.At the rest part of this thesis, by applying the middleware to a petro-china project:Smart oil field&digital faculty system, every part of the middleware would be examined if it work properly. And complete deployment and test plan are be given. At the end, conclusion would be given, demerit parts would be listed and the related solve solutions would be planned and the further work plan would be arranged.
