SDN is a new network architecture for control and data forwarding logic separation, able to provide a high degree of openness and programmability, with many advantages not available by traditional networks. But there are still some problems unsolved, for example, it is easy to cause the controller to be attacked due to the lack of verifying the source of the packet, and the limited range of match...
Discovering potential attacks on a system is an essential step in engineering secure systems, as the identified attacks will determine essential security requirements. The prevalence of Socio-Technical Systems (STSs) makes attack analysis particularly challenging. These systems are composed of people and organizations, their software systems, as well as physical infrastructures. As such, a thorough...
Authentication in Radio Frequency Identification (RFID) technology is an important requirement. Attachment of single tag in an object has less detection probability since the attached tag may not be within the communication range. Use of multiple numbers of tags in an object solves this problem and increases the detection probability. Many authentication schemes have been proposed assuming the existence...
The use of map data is often limited by the specific format and level of detail in which it is stored. We present a method that uses rule-based two dimensional scripting to enhance map data according to individual requirements of the application or the user. The method is demonstrated on OpenStreetMap data.
In recent years there has been great interest in implementing object recognition frame work on mobile phones. This has stemmed from the fact the advances in object recognition algorithm and mobile phone capabilities have built a congenial ecosystem. Application developers on mobile platforms are trying to utilize the object recognition technology to build better human computer interfaces. This approach...
The objective of this project was to develop an identification system for moving vehicles using radio frequency, with the aim of recording the times in which buses belonging to the urban transport system of passengers make their pass by a set of checkpoints located over their routes. The identification system was designed and implemented using XBee ® modules, which allows assigning a unique number...
Recent mobile device and vision technology advances have enabled mobile Augmented Reality (AR) to be serviced in real-time using natural features. However, in viewing augmented reality while moving about, the user is always encountering new and diverse target objects in different locations. Whether the AR system is scalable or not to the number of target objects is an important issue for future mobile...
This paper conducts an investigation in the domestic vehicle management standards and proposes an improved design of vehicle management system based on RFID technology. The system improves vehicle management systems in the domain of system security, data acquisition, statistical analysis, remote computer monitoring and hand-held card reader applications by integrating RFID technology with network...
In this paper we present a multi-image classification technique for mobile phones that is supported by relational reasoning. Users capture a sequence of images employing a simple near-far camera movement. After classifying distinct keyframes using a nearest-neighbor approach the corresponding database images are only considered for a majority voting if they exhibit similar near-far inter-image relations...
In this paper we present a system for mobile augmented reality (AR) based on visual recognition. We split the tasks of recognizing an object and tracking it on the user's screen into a server-side and a client-side task, respectively. The capabilities of this hybrid client-server approach are demonstrated with a prototype application on the Android platform, which is able to augment both stationary...
RFID is a Radio Frequency Identification, which has a unique advantage in data collection and data transmission. With modern logistics industry developing rapidly today, a great deal of information and automation technology is also used in logistics warehouse management system to improve efficiency. Anglicizing RFID and characteristics, this paper introduces the application of RFID in every links...
Rich online map interaction represents a useful tool to get multimedia information related to physical places. With this type of systems, users can automatically compute the optimal route for a trip or to look for entertainment places or hotels near their actual position. Standard maps are defined as a fusion of layers, where each one contains specific data such height, streets, or a particular business...
This paper describes the advantages of Cadabiaover competing network programming frameworks.Cadabia is a middleware service architecture for sharing dynamic classes and objects in network-based applications. A default database editor can either be run as a stand-alone RMI application or as a Web service. Cadabia queries can be used as properties of GUI components to read/update persistent data.Cadabia...
Mobile learning means learners can access learning resources at anywhere and anytime with mobile devices; Because these devices operate in different ways and have different capabilities, so some learning resources may not be in a format that different mobile devices accept. In order to provide learners with appropriate courses, a project on mobile learning platform supporting three-layered structure...
This paper discusses an initiative to construct a capability repository that will assist Java-ME developers in device recognition. The repository will act as a collaboration tool for developers by allowing contributions and recommendations of capability attributes. The structure and the dynamics of the proposed repository are discussed. Throughout the paper, the value of such an initiative is emphasized...
When developing ASP.NET web applications, it is important to consider all available built-in or custom techniques that will have impact on the resulting applicationpsilas performance. This article analyzes the built-in ASP.NET Cache mechanism and presents an alternative static caching custom solution. Also, introduces a utility to help find and diagnose potential caching problems in development stages...
