    Educating users for disaster management : an exploratory study on using immersive training for disaster management
    (2015-06-19) Perera, GIUS; Meedeniya, DA; Banerjee, I; Choudhury, J
    Educating users for effective disaster management skills can be a challenge that requires different levels of training support. While the training requirements can be different with respect to the contexts of managing different disaster types there can be generic training requirements that should be incorporated into all types of disaster management training. Another key aspect of disaster management training is to associate new tools and technologies that facilitate disaster management and relief work. Wireless sensor based disaster management is an emerging research area that promotes technology incorporation into different levels of disaster management tasks. In this work we explore the training for disaster management activities with wireless sensor networks. As the training platform we use a novel, yet increasingly popular and learner engaging, immersive environment OpenSim. In an OpenSim installation, a specialised training environment was developed to simulate several disaster scenarios and required wireless sensors. A set of users have successfully used the training environment and provided feedback. The next phase of the research is planned to produce a Massive Open Online Course (MOOC) to facilitate academics and students for disaster management training.

    Incorporating smart software-defined networks to enhance resilience and survivability in the cloud : survey of current challenges and future research scopes
    Banerjee, I; Perera, I; Nag, A; Choudhury, J
    With increased dependence on grids and the cloud, resilience and survivability become pre-requisites of backbone network infrastructure. Due to the unprecedented migration of data centers to both public and private cloud services; the need of an environment that provides agility combined with security and scalability becomes mandatory. The changing network scenario requires a standardized separation of data and control planes that will allow transparency and increase network resilience as metrics to improve security. Software-defined networks are being considered by many vendors to provide the ultimate solution to meet the increasing demands and serve the elastic growth of cloud services while providing sufficient flow monitoring, fault detection, and network management properties in highly-complex backbone infrastructure networks.

    Introducing immersive technologies for learning : a study evaluating the readiness for using virtual worlds for learning and teaching in an Indian University
    Banerjee, I; Perera, GIUS; Choudhury, J
    This paper presents a case study demonstrating successful involvement of a shared online 3D virtual world as an educational aid, for teaching Networks and communication, to both first year and final year students in an engineering college in India. While virtual worlds have been incorporated into regular form of studies in many universities world-wide, Indian universities such as the one being examined are yet to explore such new technologies to encourage attentiveness among students to study complex subjects and stimulate independent learning. This study was conducted to identify whether the selected university can be benefited from such technology to assist learning tasks that promote student learning engagement. It also discusses the outlook of faculty members and students to determine their acceptance to integrate immersive learning into the regular curriculum. The paper is arranged as follows: Section I introduces the nature of the paper and the reason of survey and development of the virtual environment. Section II focuses on the related background work on virtual education and its importance. Section III explains the building process in virtual environment and explores the design decisions made. Sections IV mainly discusses the survey undertaken, its procedure and setup. Results are finally discussed in Section V followed by Section VI which focuses on conclusion.
