In order to satisfy the practice management requirement of inland small and medium enterprises, this paper designs a lightweight Radio Frequency IDentification(RFID) middleware. Its architecture is between being centered with basic framework and centered with application program, and it simplifies the Application Level Event(ALE) structure of Electronic Product Code(EPC) system. Based on Application Program Interface(API), it implements lightweight middleware by integrating and filtering thought of database. This lightweight middleware has simple structure, short development cycle, and it is easy to maintain and extend at later period.
According to the insufficiency of Internet of Things(IOT) on information transmission, a trusted anonymous information transmission protocol of IOT is proposed with trusted computing technology. In the protocol, information servers of things encode the details of things layer by layer according to the order of response nodes. In the transmission process, the data are decoded at every passed node until the local ONS server data are totally decoded. Meanwhile, the respond nodes can tell whether the received information is changed by some relevant information. The analysis shows that this protocol is safe, anonymous, trusted, attack-resistant, etc.
This paper designs Things Oriented Architecture(TOA) and Things Oriented Communication(TOC) middleware which is consist of device Agent, TOC client, and TOC server. TOC is capable of isolating the innumerable diversity of Internet of Things(IOT) objects and providing a unified interactive service and platform by applying Extensible Messaging and Presence Protocol(XMPP) and Pipe & Filter design mode. It implements TOC in the hospital medical trash management system. The results are very promising. It indicates that TOC can provide a unify system integration platform and enough flexible in IOT objects implementation.
Aiming at the security problem of maliciously tracking, amending and impersonation existing in original Radio Frequency IDentification(RFID) middleware, this paper presents a RFID middleware reconfigurable security framework. It uses Service-Oriented Architecture(SOA) and Open Service Gateway initiative(OSGi) plug-in architecture to reduce coupling between some component, enhance reusable, and research and binding component service. It goes on security state monitoring by life cycle management to realize real-time dynamic operation management. Test result shows that this framework has the characteristics of dynamical expansion, centralized management and complete modular, it also can enhance application efficiency of RFID, and strengthen reliability and security.
The architecture of UHF Radio Frequency Identification(RFID) is designed and simulated based on ISO/IEC18000-6 protocol UHF RFID protocols. The transmitter and receiver of RFID system are achieved and the backscatter technology is verified in multi-path fading and AWGN channel. The relationship between signal-to-noise and bit-error-ratio is given, which offers references to system application in scientific and reasonable design of RFID system.
Using the status of water environmental pollution and monitoring management in Xi’an as its starting point, and combining with the low level of national monitoring and pollution increasingly serious problem, remote monitoring and intelligent system analyzing water quality of rivers and lakes is developed. The system consists of fixed-site remote monitoring sites, mobile wireless monitoring sites and biological monitoring sites, therefore, full-coverage and real-time water monitoring network is established. Experimental results show the system has functions of measurement data encrypted transmission, excessive alarm, real-time measurement data storage, scientific decision-making, and indicates the system has low power consumption, high reliability and easy installation ability and good practical significance.
This paper presents an Internet of Things(IOT) application fundamental framework based on Service Oriented Architecture(SOA) in order to effectively integrate different enterprise services and decrease the loss of repeated work. The fundamental framework divides the SOA into six layers from original three layers, defines the functions of each layer, and gives two kinds of implemental technologies——.Net and Java platform. It uses radio frequency identification to build the IOT that solves whole process control problem, and uses a service-oriented architecture technology to achieve massive data sharing and efficient use of resources. The fundamental application framework is a feasible solution for enterprise resource integration.
This paper introduces the recognition and orientation of objects in Internet of Things(IOT), analyzes Augmented Reality(AR) virtual interactive methods of IOT based on data glove, designs and realizes a virtual prototyping technology. Experimental results show the features of combining virtual and real objects, the natural experience provided to users, and the satisfaction of the application of IOT in the requirement of real time, precision and stability.
Aiming at the specific traffic difficulty at the ramp corner, this paper proposes a traffic reminder system based on Wireless Sensor Network(WSN). The knowledge reduction of rough set theory is used to get the minimum set of reminder. It simplifies the design of the control circuit. It designs the intelligent control circuit using the state diagram based on the finite state automaton, which brings down the cost of hardware further. Experiment results indicate that knowledge reduction reduces the quantity of the remainders and the system states sets, and it reduces the cost of the hardware effectively, and increases the reaction velocity of the system.
