Research and Realization on the Model of Neonates Surveillance System Based on RFID

With the costs of RFID Tags and Readers reduced, it’s be used more and more widely. In recent years researchers began to pay more attention on the model of RFID applications. This paper briefly introduces the constitution and principle of RFID technology. Next, it elaborates the design and application of a data model according to the RFID-Based neonates surveillance system.

Design and Implementation of an LBS Application Server Software Based on the PUB/SUB Paradigm

This paper gives out a PUB/SUB-based application server software, which aims at improving the coarse granularity of the pushed information in current LBS systems. Taking the advantage of PUB/SUB systems asynchronous, loosely-coupled and multiplex communication mechanism, the server software pushes LBS information with its granularity refined. By combining position information and the PUB/SUB paradigm, users can easily focus on his points of interest. In this paper, three message formats, which are used in the communication between client app and server, are introduced and overall architecture is presented. Furthermore, in order to support indoor and outdoor service, a positioning middleware is also applied. The process of subscription matching utilizes a hash table to speed up the rate. Experimental result shows that the software could offer an efficient service to users.
