This paper describes the vertical handover architecture with low latency handover for mobile terminals which supports interworking between heterogeneous networks. The vertical handover architecture defines handover-related modules for mobile terminal and the handover switching flows among them. We adapt low latency handover method to mobile IP for reducing handover time. The architecture is designed to be easily extended to support more than two heterogeneous networks, so that it is easy to apply architecture to terminals that have multiple heterogeneous wireless network interfaces. We analyze the performance of handover method in terms of handover delay time using test bed system.

This paper describes the design and implementation of mobile location-awareness service based on embedded Linux. In mobile location-awareness, the picture and GPS information at mobile terminal are stored on server through wireless network. With the mobile location-awareness, user can easily identify the location where the picture was taken on through Yahoo map. The implemented mobile location-awareness also helps user to manage pictures according to the location where they were taken and visit that place again. We verified functions of mobile location-awareness using MCC mobile terminal made by ETRI.

The paper describes the design and implementation of Qplus Smartphone Edition based on embedded Linux. Existing Smartphone platforms entailed royalty expenses and had customization difficulties due to the closure of their source codes. The Qplus Smartphone Edition requires no royalty because it is based on the embedded Linux. And, it supports key navigation functionality such as moving between folders or running applications with key-only operations. It also provides more user friendly environment through screen interfaces and indicators similar to those of the cellular phones.

Covert channel mitigation method for secure real-time database using capacity metric

Tongxin Xuebao/Journal on Communications 2008年第8期29卷 46-56页

作者： Zeng, Hai-Tao Wang, Yong-Ji Ruan, Li Zu, W. Cai, Jia-Yong Lab for Internet Software Technology Institute of Software Chinese Academy of Science Beijing 100190 China Key Laboratory for Computer Science Chinese Academy of Sciences Beijing 100190 China Graduate University Chinese Academy of Sciences Beijing 100049 China National Engineering Research Center for Fundamental Software Institute of Software Chinese Academy of Science Beijing 100190 China Integrate Information System Research Center Institute of Automation Chinese Academy of Science Beijing 100190 China

A capacity using covert channel mitigation method (CUCCMM) was proposed. This method uses capacity as metric for channel danger measure according to trusted computer system evaluation criteria (TCSEC) and multiple probabilities based protocol selection policy (MPBPSP) to guide die application of secure concurrency control protocol. The algorithms of channel's capacity measure and policy's parameter computing are also presented. Experimental results show that CUCCMM implements the restriction criterion on channel's capacity effectively and accurately, and the MPBPSP significantly decreases the influence of restriction operation on real-time performance.

Context-sensitive mobile applications require a certain amount of flexibility due to the fact that they have to provide services for many different situations. The limited resources available make resource management a major challenge in such applications. In this paper, we present different techniques for the efficient use of resources of mobile devices. These techniques support the development of adaptable and flexible context-sensitive applications.

In this paper, we propose the basic framework of point- wise topological logic on completely distributive lattices and explore approximate reasoning in it. The logic of this paper is based on pointwise characterization, therefore the pointwise conception is pervasive. We explore approximate reasoning in abstract logical framework Fl on completely distributive lattice L. We propose the structure of point- wise topological logic F TL , the structure of matching function sigma. and the structure of matching neighborhood group. We investigate approximate reasoning in pointwise topological logic F TL with matching function sigma, develop pointwise topological algorithm of simple approximate reasoning, introduce the essential characteristics of this scheme.

Wearable computer can be worn anytime with the support of unrestricted communications and variety of services which provides maximum capability of information use. Key challenges in developing such wearable computers are level of comfort that users do not feel what they wear, easy and intuitive user interface and power management technique. This paper suggests a wearable system that consists of a wristwatch-type gesture recognition device and a personal mobile gateway that functional input/output modules can be freely plugged in and taken out. We describe our techniques implemented during our wearable system development: 1) multimodal fusion engine that recognizes voice and gesture simultaneously, 2) power management technique and 3) gesture recognition engine. Finally, we evaluate the performance of our multimodal fusion engine, and show the power consumption measurement data of our system built with the power management technique. © Springer-Verlag Berlin Heidelberg 2007.
