Personal profile

I was awarded my BSc, Mphil and PhD in computer science at Nankai University, Dalian University of Technology and 羞羞视频 in 1991, 1994 and 2007. My PhD thesis focuses on modernising legacy systems through model construction and transformation. A unified approach is proposed in the context of Model Driven Architecture (MDA) to extract different level of models from legacy source code.

I have been an active researcher in the area of software engineering and knowledge engineering, focusing on its emerging themes including Service Oriented Architecture, Model Driven Architecture, Cloud/Edge Computing, Mobile Computing, Internet of Things and Cyber Physical System, with the long term aim of building a coherent set of conceptual frameworks, methods and tool support for the development of Smart Environments and Ambient Assisted Living Systems.

I have a strong background in a combination of academic research and industrial application. I have gained invaluable understanding of system software, distributed systems, real-time systems, critical systems and security systems through many projects. As research outputs, I have published 74 research papers in refereed conferences and Journals.

dc.title: Survey of IP-based air-to-ground data link communication technologies dc.contributor.author: 脰zmen, Sergun; Hamzaoui, Raouf; Chen, Feng dc.description.abstract: The main purpose of an air traffic management system is to provide air traffic services to an aircraft moving within the controlled airspace. Very high frequency (VHF) radio in continental regions, as well as high frequency (HF) radio and satellite communications in remote areas, are used today as the primary way of delivering air traffic services. The technical limitations and constraints associated with the current technology, such as line-of-sight requirement, vulnerability to interference, and limited coverage, cause degraded voice quality and discontinuity in service. At the same time, voice-based communication may affect flight safety due to poor language skills, call sign confusion, and failure to use standard phraseology. For this reason, text-based communication over a VHF data link (VDL) has been proposed as an alternative. However, it is predicted that VDL will be insufficient to support increasing air traffic and intensive data exchanges due to its lack of mobility support and limited resources to ensure service continuity. This paper surveys next-generation data link technologies based on the current state of the "industry standard" for aeronautical communication. These include Aeronautical Mobile Airport Communication System (AeroMACS), L-band Digital Aeronautical Communications System (LDACS), and Airborne New Advanced Satellite Techniques & Technologies in a System Integrated Approach (ANASTASIA). The paper also surveys IP-based text communication solutions over these next-generation data links. We analyze the efficiency of the proposed solutions with regard to service continuity and aeronautical application requirements. We conclude the survey by identifying open problems and future trends. dc.description: open access article
dc.title: Component Profiling and Prediction Models for QoS-Aware Self-Adapting DSMS Framework dc.contributor.author: Yagnik, Tarjana; Chen, Feng; Kasraian, Laleh dc.description.abstract: Quality of Service (QoS) has been identified as an important attribute of system performance of Data Stream Management Systems (DSMS). A DSMS should have the ability to allocate physical computing resources between different submitted queries and fulfil QoS specifications in a fair and square manner. System scheduling strategies need to be adjusted dynamically to utilise available physical resources to guarantee the end-to-end quality of service levels. In this paper, we present a proactive method that utilises a multi-level component profiling approach to build prediction models that anticipate several QoS violations and performance degradations. The models are constructed using several incremental machine learning algorithms that are enhanced with ensemble learning and abnormal detection techniques. The approach performs accurate predictions in near real-time with accuracy up to 85% and with abnormal detection techniques, the accuracy reaches 100%. This is a major component within a proposed QoS-Aware Self-Adapting Data Stream Management Framework.
dc.title: QoS-Aware Self-Adapting Resource Utilisation Framework for Distributed Stream Management Systems dc.contributor.author: Yagnik, Tarjana; Chen, Feng; Kasraian, Laleh dc.description.abstract: The last decade witnessed plenty of Big Data processing and applications including the utilisation of machine learning algorithms and techniques. Such data need to be analysed under specific Quality of Service (QoS) constraints for certain critical applications. Many frameworks have been proposed for QoS management and resource allocation for the various Distributed Stream Management Systems (DSMS), but lack the capability of dynamic adaptation to fluctuations in input data rates. This paper presents a novel QoS-Aware, Self-Adaptive, Resource Utilisation framework which utilises instantaneous reactions with proactive actions. This research focuses on the load monitoring and analysis parts of the framework. By applying real-time analytics on performance and QoS metrics, the predictive models can assist in adjusting resource allocation strategies. The experiments were conducted to collect the various metrics and analyse them to reduce their dimensions and identify the most influential ones regarding the QoS and resource allocation schemes.
dc.title: Agentification for web services dc.contributor.author: Chen, Feng; Yang, Hongji; Guo, He; Xu, Baowen dc.description.abstract: We report our effort on the AgenEvo project, which develops an evolution approach to re-engineer legacy systems into agent-based Web services. We first survey the key technologies, which are adopted in this paper. After discussing the basic features of the Web services and agent, we focus on agent-based Web services, which are hot spot in web-based research area. We argue that agent-based Web services are well suited to building software solutions for distributed, open and dynamic web-based systems. Next, we introduce our approach on re-engineering framework and working flow. The method that integrates agents with Web services for legacy system evolution is proposed and an example on how to use agent-based Web services software evolution framework and methodology to re-engineer the legacy system is illustrated. Finally, we conclude the paper and suggest the directions of the possible future research.
dc.title: Agent-based Web services evolution for pervasive computing dc.contributor.author: Liu, Ruimin; Chen, Feng; Yang, Hongji; Chu, William Cheng-chung; Lai, Yu-Bin dc.description.abstract: Pervasive computing will be a fertile source of challenging research problems in computer systems for many years to come. The ability to obtain services and information from an environment anywhere at anytime is part of pervasive computing. The problem is that most of existing services and applications are designed for stationary PCs. How to evolve these so called legacy system towards those mobile users in a controlled manner is vital for that pervasive computing can become more widespread. In this paper, we report our efforts on the PerEvo project. After discussing the basic features and challenges of pervasive computing, we present an agent-based Web services evolution approach, which is well suited to building software solutions for pervasive computing, and illustrate our solutions through a booking scenario.
dc.title: Feature analysis for service-oriented reengineering dc.contributor.author: Chen, Feng; Li, Shaoyun; Yang, Hongji; Wang, Ching-Huey; Chu, William Cheng-chung dc.description.abstract: Web services together with service-oriented architectures (SOA) are playing an important role in the future of distributed computing, significantly impacting software development and evolution. With the adoption to Web services technology, more and more existing non-service-oriented software systems turn to be legacy systems. They require a service-oriented reengineering process in order to survive in service-oriented computing environment. If the reengineering goal is to expose the services of a single object or any underlying function-oriented middleware, many problems will arise including semantic mismatches, service granularity issues and state management. Attempting to masquerade software assets from a lower level of abstraction can often cause significant mismatch and exposure problems. In this paper, by using feature analysis, an approach to supporting service-oriented reengineering is presented. Service identification and packaging process are performed and resulted into a service delegation.
dc.title: A Formal Model Driven Approach to Dependable Software Evolution dc.contributor.author: Chen, Feng; Yang, Hongji; Qiao, Bing; Chu, William Cheng-chung dc.description.abstract: The paper proposes a unified formal model driven approach to software evolution based on both program transformation and model transformation of legacy systems. A formal model definition ensures a consistent interpretation of the legacy system and provides a theoretical foundation for dependable software evolution. The theoretical foundation is based on the construction of a wide spectrum language for reengineering, known as WSL, which enjoys a sound formal semantics. The architecture and working flow of the approach are proposed, and the mappings between WSL and PSL in MDA provide an engaging combination of traditional program transformation and modern model transformation, which shows that the proposed approach is feasible and promising in its domain. A prototype tool is developed to test the approach and a case study is used for experiments with the proposed approach and the prototype tool. Conclusion is drawn based on analysis and further research directions are also discussed
dc.title: Model oriented evolutionary redocumentation dc.contributor.author: Chen, Feng; Yang, Hongji dc.description.abstract: This paper discusses aspects of the redocumentation of legacy systems and proposes a model oriented approach to generating documentation, which is to produce models from existing systems and to generate the documentation based on the models. Since the software models can bridge the gap of a legacy system and an evolved system, the generated documentation covers all the information of system evolution. A prototype software redocumentation tool is presented to semi-automate this process and a case study of a system in IBM assembler is used for experiments with the approach and the prototype tool.
dc.title: A Home-Based IoT-Enabled Framework for Sleep Behaviour Assessment dc.contributor.author: Fallmann, Sarah; Chen, Liming; Chen, Feng dc.description.abstract: Sleep has an impact on a person's life including their health and wellbeing, thus assessing sleep behaviour is of high importance to gain insight into people's general health status. In general, current sleep behaviour assessment is restricted to a controlled scenario within a hospital environment limited by the time of monitoring and to specific factors. As healthcare is shifting from reactive to preventive and predictive care with the support of digital health and IoT technology, there is a growing demand to make sleep assessment possible at home. In this paper, we propose a sleep behaviour assessment framework considering different facets of sleep such as sleep quality, regularity, circadian rhythm, environmental conditions and sleep hygiene. Hence, we describe methodologies and techniques which can help realise home-based sleep assessment. A salient feature of the framework is that it takes into account personal preferences and influential factors as well as doctor's recommendations and clinical history, thus, allowing personalised medical and behavioural assessment. In addition, the proposed framework supports a modular service-oriented design adaptable to both doctor and user needs and availability of underpinning technologies.
dc.title: ICA-Based EEG Feature Analysis and Classification of Learning Styles dc.contributor.author: Alhasan, Khawla; Aliyu, Suleiman; Chen, Liming; Chen, Feng dc.description.abstract: A thorough investigation of the electroencephalograph (EEG) information may support an enriched awareness of the mechanism of understanding different learning styles patterns. Wavelet analysis is a powerful technique that uniquely permits the decomposition of complex information of trends, discontinuities, a repeated pattern. The purpose of such methods is to be able to assign simple segments at diverse locations and scales, to be remodelled afterward effectively. In this paper, we attempt to classify individual cognitive learning styles using artificial neural networks and unsupervised learning. First, we apply Independent component analysis (ICA) to extract relevant features (artefacts removal) of the EEG records. We analyse the ICA-based EEG channels data using inter-quartiles to show the degree of dispersion and skewness. Next, self-organising maps (SOM) are then created to characterise different cognitive learning styles from selected ICA-based channel data.
