For notification distribution, we have designed and implemented a mobile device management system called Meta XA. Meta XA is based on an event-driven architecture combined with the complex event processing technology. In this paper, we propose an approach to bringing Meta XA into the cloud computing domain, without having to change its architecture.
The introduction of Web and mobile technologies has recently improved research endeavors such as research planning, literature searching, or data gathering. Nevertheless, little attention has been paid to an adaptation of mobile technology into research support systems. We argue that it is viable to extend the applicability of current mobile technology to research support systems by analyzing research...
With the development of 3G mobile technology, the mobile learning (M-Learning) platform research becomes the demand of the Times. Based on cloud service for convenient hardware resource allocation and ontology for good individual learning, the system architecture of mobile learning platform is proposed and some key techniques are studied in this paper. Finally, a kind of M-learning platform framework...
With the incoming times of multi-core architecture, the mobile platform will focus on the chip multiprocessor design too. To fully exert this advantage, the software can be component-based development to use the multi-threading characters. In this paper, thread is encapsulated by the component model for the support of the CPU cores and the easy development of the large program. Some research about...
In this paper, we introduce and evaluate ScaleMesh, a scalable miniaturized dual-radio wireless mesh testbed based on IEEE 802.11b/g technology- ScaleMesh can emulate large-scale mesh networks within a miniaturized experimentation area by adaptively shrinking the transmission range of mesh nodes by means of variable signal attenuators. To this end, we derive a theoretical formula for approximating...
Considering the high packet losses and low, varying bandwidth of GPRS/EDGE network and limited computation power of handheld devices, we present and implement a novel SVC video-on-demand system for hand-held devices over GPRS/EDGE network. For the purpose of handling varying bitrate, we propose a priority based layer switching (PLS) adaptation scheme for SVC stream, which not only performs online...
The following topics are dealt with: communication systems and networks; computer architecture and VLSI; computer science, information science; control systems; intelligent systems; data mining, data warehousing and database; image processing and pattern recognition; image, acoustic, speech and signal processing; information management systems; intelligent agent technology; agent based systems; Internet...
Information privacy is usually concerned with the confidentiality of personally identifiable information (PII), such as electronic medical records. Nowadays, Web services are used to support different applications which may contain PII, such as healthcare applications. Thus, the information access control mechanism for Web services must be embedded into privacy-enhancing technologies. Further as application...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
Currently, robots are being used as teaching tools and can be found in K-12 and college classrooms. The primary appeal associated with employing robots is that they tend to capture the attention of the target audience and thereby facilitate the learning process. While there are numerous robotic kits on the market today, few can be used to teach both high-level concepts in computer science and engineering...
Remote-sensing data about the Earth's environment is being created at an ever-increasing rate and distributed among heterogeneous remote sites. Traditional models of distributed computing are inadequate to support such complex applications, which generally involve a large quantity of data. The authors describe a mobile agent based architecture for analyzing and managing data for the Synthetic Aperture...
