      • Challenges in Managing MobileIP Networks

        Kazuhide Koide,Glenn Mansfield Keeni,Norio Shiratori 대한전자공학회 2008 ITC-CSCC :International Technical Conference on Ci Vol.2008 No.7

        Several of the implicit assumptions of traditional network management do not hold in networks supporting mobility. The location of a node changes, the RTT between two nodes may fluctuate over a relatively large range and unreachability is not a definite symptom of failure. In this work we propose FCAPS + L, an extension of the management framework, that supports mobility. We examine the management issues related to mobility, the information requirements to address these issues and the technology required to make the information available to a manager or management application.

        Sharing Information for Event Analysis over the Wide Internet

        Nagao, Masahiro,Koide, Kazuhide,Satoh, Akihiro,Keeni, Glenn Mansfield,Shiratori, Norio The Korea Institute of Information and Commucation 2010 Journal of communications and networks Vol.12 No.4

        Cross-domain event information sharing is a topic of great interest in the area of event based network management. In this work we use data sets which represent actual attacks in the operational Internet. We analyze the data sets to understand the dynamics of the attacks and then go onto show the effectiveness of sharing incident related information to contain these attacks. We describe universal data acquisition system for event based management (UniDAS), a novel system for secure and automated cross-domain event information sharing. The system uses a generic, structured data format based on a standardized incident object description and exchange format (IODEF). IODEF is an XML-based extensible data format for security incident information exchange. We propose a simple and effective security model for IODEF and apply it to the secure and automated generic event information sharing system UniDAS. We present the system we have developed and evaluate its effectiveness.

        Feasibility of Societal Model for Securing Internet of Things

        ( Hiroshi Tsunoda ),( Rodrigo Roman ),( Javier Lopez ),( Glenn Mansfield Keeni ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.8

        In the Internet of Things (IoT) concept, devices communicate autonomously with applications in the Internet. A significant aspect of IoT that makes it stand apart from present-day networked devices and applications is a) the very large number of devices, produced by diverse makers and used by an even more diverse group of users; b) the applications residing and functioning in what were very private sanctums of life e.g. the car, home, and the people themselves. Since these diverse devices require high-level security, an operational model for an IoT system is required, which has built-in security. We have proposed the societal model as a simple operational model. The basic concept of the model is borrowed from human society - there will be infants, the weak and the handicapped who need to be protected by guardians. This natural security mechanism works very well for IoT networks which seem to have inherently weak security mechanisms. In this paper, we discuss the requirements of the societal model and examine its feasibility by doing a proof-of-concept implementation.

        Development of a WLAN Based Monitoring System for Group Activity Measurement in Real-Time

        Hiroshi Tsunoda,Hidehisa Nakayama,Kohei Ohta,Akihiro Suzuki,Hiroki Nishiyama,Ryoichi Nagatomi,Kazuo Hashimoto,Yuji Waizumi,Glenn Mansfield Keeni,Yoshiaki Nemoto 한국통신학회 2011 Journal of communications and networks Vol.13 No.2

        In recent years, there has been a rise in epidemiological evidence suggesting the health benefits of a physically active lifestyle. However, it is not always easy for individuals to personally recognize the optimal conditions for exercise and physical activity. Wearable acceleration-based pedometers have become widely used in estimating the amount of physical activity, and to a limited extent,providing information regarding exercise intensity, but they have never been used to assess adaptation to exercise. In order to realize simultaneous activity monitoring for multiple users exercising outdoors, we developed a prototype wireless local area network (WLAN) based system. In our system, a WLAN is deployed outside, and a user wearing a smart phone and monitoring device exercises freely within the coverage area of the wireless network. By doing so, the developed system is able to monitor the activity of each user andmeasures various parameters including those related to exercise adaptation. In a demonstration experiment, the developed system was evaluated and used to monitor users enjoying a Nordic walk, after which users were immediately able to receive their exercise report. In this paper, we discuss the requirements and issues in developing an activity monitoring system and report the findings we obtained through the demonstration experiment.
