CAFISE: An approach to enabling adaptive configuration of service grid applications

Aiming at building up more powerful, open-standard-based and generic infras-tructures for application integration, service grids address the challenges in large-scale coordinated sharing and on-demand composition of network-based application services. The related endeavors have opened up new ways of application development, deployment and integration. In connection with the new level of scale, openness and dynamism brought forward by service grids, adaptive service configuration is of essential importance to applications. This paper proposes an approach called CAFISE, which tries to better facilitate on-demand configuration and dynamic reconfigura-tion of service grid applications. In CAFISE, a business design and its supporting software system are considered in a coherent way, and a convergent relation, which helps to map business-level configurations to software-level configurations, is highlighted. The paper is particularly devoted to presenting and discussing the principles, reference model, modeling language and supporting application framework of CAFISE. Since practical usefulness is highly valued in the development of CAFISE, the application of the approach to a real-world scenario is also presented in the paper.     

A cross-layer fault tolerance management module for wireless sensor networks

It is a well-established fact that wireless sensor networks (WSNs) are very power constraint networks, but besides this, they are inherently more fault-prone than any other type of wireless network and their protocol design is very application specific. Major reasons for the faults are the unpredictable wireless communication channel, battery depletion, as well as fragility and mobility of the nodes. Furthermore, as traditional protocol design methods have proved inadequate, the cross-layer design (CLD) approach, which allows for interactions between different layers, providing more flexible and energy-efficient functionality, has emerged as a viable solution for WSNs. In this study we define a fault tolerance management module suitable to the requirements, limitations, and specifics of WSNs, encompassing methods for fault detection, fault prevention, fault management, and recovery. The suggested solution is in line with the CLD approach, which is an important factor in increasing the network performance. Through simulations the functionality of the network is evaluated, based on packet loss, delay, and energy consumption, and is compared with a similar solution not including fault management. The results achieved support the idea that the introduction of a unified approach to fault management improves the network performance as a whole.

Environmental Monitoring in Museums Based on Wireless Sensor Network via Cell Phone

Conservation of artworks in museums is a crucial issue to prevent their degradation. Thus, it is fundamental to continuously monitor the environment where artifacts are located. The WISE-MUSE project proposes the use of WSNs （wireless sensor networks） to carry out monitoring and automatically control of museums＇ environment and structural health. The deployment of a WSN can help to implement these measurements continuously, in a real-time basis, and in a much easier and cheaper way than when using traditional measuring equipment and procedures. Nevertheless, continuous monitoring implies providing immediate information of any abnormal value detected in the museums＇ environment. Thus, this contribution arises： the development of a new mobile application that allows users to continuously monitor the environment, but specially helps them to be more aware of any undesirable changes that may occur.
