Research And Development Of Push Engine Based On Context-aware

With the fast development of RFID technology and other Sensor technologies, thetechnology of context-aware has been widely used in many fields. Context-aware is atechnology which can make the computer sense the current environment from various sensorsand the related technologies.The current workflow of context-aware systems can be devidedinto four steps：sensing, modeling,inferencing, pushing. The current research of context-awaresystem is mainly focused on the previous three steps. But the research of pushing is ignored.In this paper, we combined the domestic and foreign research status and kept analysising theadvantages and disadvantages of the current context-aware systems. Finally, we put forwardand designed the push engine based on context-aware which is flexable and can be easilyextended.In this paper，the push engine based on context-aware extended the current context-awaresystem with the simple context-aware engine,the push engine,the server push module ofmuti-users and muti-ways and other components. The system can choose the fastest ways toprocess the context information and send the information to the users according to differentuser requests and different types of user requests. The engine can not only complete the existing perception of the basic functions of the system, but also greatly improve theefficiency. The paper paid deeply attention on two important components--the simplecontext-aware engine and the server push module of muti-users and muti-ways. The simplecontext-aware engine deleted a set of complex components，designed various contextdrivers to process different context data and used dispatcher to choose the context drivers.Allthese designs can accelerate the speed of processing the context information. The server pushplatform of muti-users and muti-ways used the push architecture of muti-users and muti-wayand implemented the efficient push service.The paper is organized as follows: firstly，we describe the research background,including related concepts of context-aware and server push.Then we analyze the researchstatus of context-aware systems and groups the the domestic and foreign context-awaresystem architecture into two types: the architecture for specific systems and the architecturefor general systems. We analyzed their features, advantages and disadvantages. Thirdly, wecombined the server push technology and put forward the push engine based on context-aware.We conducted a thorough study and design on the simple context-aware engine, the pushengine based on context-aware and the server push platform of muti-users and muti-ways.Finally, we introduce the detailed implementation solution of each component in thisarchitecture, as well as program verification.
