●健全、高效、节能的无线传感器网络
     无线传感器网络是一种新技术的应用范围广泛(从环境监测,监视),但受能源制约,许多到一个流量,多余的低速率数据的数量。已经提出了许多路由协议,传感器网络,旨在实现能源效率,但这些协议很少注意的鲁棒性和容错。该项目解决容错,在Ad-hoc传感器网络路由,即一个强大和高效节能区分本地和大型交通之间的路由协议的设计和发展。提出一个新的多路径路由协议和模拟。    
●WSDL / BPEL的SRML语言转换
     SRML是欧洲项目的Sensoria参考建模语言。它提供了业务流程建模和推理原语。项目开发从两个基于具体行业标准的SRML模型:业务流程执行语言(BPEL)和Web服务描述语言(WSDL)。SRML模型编码提供了手段,创建BPEL/ WSDL的规格,用于构建更复杂的业务流程模型,并且可在其他语言中指定的组件使用高层次的声明描述。    
●文献信息的XML数据库
     在工业界和学术界的许多人都使用称为LaTex文档排版系统。LaTex文档可以用多种格式公布,包括报告,期刊论文,会议记录,撰写书籍等等。 BiTex则用于格式化的参考文献。虽然非常有效的,BiTex由于其低级别的抽象,使其难以成为共享工具,如执行不同的活动(例如,公司内部的技术和营销人员之间)的人之间的文献信息。为了解决这个问题,本项目开发了一个基于XML的文献信息管理框架。
    
A selection of recent MSc projects
●Robust and Energy Efficient Wireless Sensor Networks
     Wireless sensor networks are a new technology with a wide range of applications (from environment monitoring to surveillance) but subject to a number of energy constraints, many-to-one flows, and redundant low-rate data. Many routing protocols have been proposed for sensor networks that aim at achieving energy efficiency, but with little or no attention to robustness and fault-tolerance. This project addressed fault-tolerance in ad-hoc sensor network routing, namely the design and development of a robust and energy efficient routing protocol that distinguishes between local and large-scale traffic. A new multipath routing protocol was proposed and simulated which follows the “number of hops” metric and employs a waiting time before transmitting messages to sink.    
●WSDL/BPEL to SRML language Transformation
     SRML is the Reference Modelling Language of the European project SENSORIA. It provides primitives for modeling and reasoning about business processes in a way that is independent of the languages used for executing them. This project developed a tool for generating SRML models from two specific industry standards: The Business Process Execution Language (BPEL), which is used for specifying business process based on Web Services, and the Web Services Description Languages (WSDL) – an XML format for describing network services. The encoding provides the means to create high-level declarative descriptions of BPEL/WSDL specifications that can be used for building more complex business process models that can include components specified in other languages.    
●XML Database for Bibliographic Information
     Many people in industry and academia use a document typesetting system called LaTex. Documents may be published in various formats including reports, journal articles, conference proceedings, authored books, and so on. BiTex is the tool used by LaTex for formatting lists of references that are to be incorporated within these documents. Although it is very effective, BiTex has raised a practical concern due to its low-level of abstracting, making it difficult to share bibliographic information among tools or people executing different activities (for instance, between the technical and the marketing staff within a company). In order to address this concern, this project developed an XML-based framework for managing bibliographic information that imports/exports BibTex references.
