    Impact of application layer over wireless sensor networks
    (12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Ramassamy, Cédric; Fouchal, Hacène; Hunel, Philippe
    Applications over Wireless Sensor Networks (WSNs) are various and different. Many routing protocols have been proposed for WSNs since a many years. Medium Access Control (MAC) protocols can differ from a network to another. The transmission range can also be variable from a sensor to another depending on their battery capacities. All these various protocols have an influence on the WSNs. It is worthy to choose the appropriate protocol for each specific situation in order to ensure high security of the network. In this paper, we show that the type of applications has a real impact on WSN. In- deed, each kind of application with a specific routing protocol, MAC layer and transmission range value impact on security of network in terms of packets lost rate. We have undertaken a set of experimentations in order to show the importance of an appropriate configuration to deploy a WSN with a high security confidence degree. For the application layer, we have handled three types of applications. For the routing layer, we have handled only with AOMDV protocol. For MAC layer we use 802.15.4 protocols. We have conducted many simulations through the NS-2 simulator in order to analyze one relevant security indicators on WSNs: lost packet rate.

    On the adoption of usage control technology in collaborative environments
    (12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Ahlmann Nyre, Åsmund; Jaatun, Martin Gilje
    The extensive collaboration across system boundaries facilitated by the Internet is unfortunately also increasing the potential for misuse of shared information. While mechanisms to protect assets from active attackers (such as firewalls, intrusion detection systems and anti-virus software) are commonplace, the availability of commercial software to protect information from misuse remains limited. Businesses employ non-disclosure agreements, but have no means to prevent or detect violations of these. Usage control has been proposed as the means to protect information even after its distribution. However, despite the efforts to develop new usage control technology and the apparent need for it, the industry is less enthusiastic. In this paper we investigate existing theories of technology adoption in order to better understand the industryperspective and to improve technology development. We base our study well-known general theories on protection motivation, innovation diffusion and technology acceptance. We then utilize these theories and preliminary results of a case study to build a new model for understanding usage control technology acceptance.

    Context-awareness and real-time information in an intelligent smartphone application
    (12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Marcussen, Christoffer Jun; Eliassen, Lars Moland; Sætre, Rune; Gambäck, Björn
    With the constant increase in smartphone sales, integrated sensors and map navigation have now become available to the average user. This allows for mobile applications to use context-awareness to provide more relevant information. An interesting use-case for such applications is a route information system for buses. The paper describes an application which interfaces over a mobile phone to Bus- TUC, a natural language-based reasoning-system for bus routes in Trondheim. By combining user context, BusTUC reasoning and real-time data from the bus service provider, the user-interaction is simplified, compared to a standard information system. We discuss issues on supporting context-awareness and real-time information in this system, comparing it to other available route information systems. Feedback from beta-testers indicates that the application suits the needs of typical bus travellers well.

    Urban traffic system, computer networks and powergrids: different systems – same solutions?
    (12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Unger, Herwig
    In the last decade, technical and logistic systems became more and more specialised, complex and in most cases globally distributed. Already today, it is not possible to oversee or control them from any centralised instance. Nevertheless, from the modelling point of view and their mathematical background those networks seem to have a lot in common. The author gives a comparison of urban traffic systems, peer-to-peer computer networks and power grids. In a set of examples will be shown, how an interdisciplinary application of methods and principles from one system may contribute to the progress of other ones. Last but not least, it is intended to show that self-organisation will be the key issue to guarantee the efficient work of those systems in the future. We argue that selforganisation not only come along with structure building but also demonstrate that a suitable structure building may support the emergence of work division and cooperation.

    Probabilistic event processing for situational awareness
    (12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Preuveneers, Davy; Landmark, Andreas D.; Wienhofen, Leendert W. M.
    Over the last century the continuous innovation of technology, coupled with a steady increase in the size of the healthcare organizations, has created a need for information systems supporting healthcare professionals with their daily tasks and decisions. Modern hospitals are full of technology producing electronic records of events and activities, with the opportunity of these events culminating in a wealth of information that these semi-autonomous experts can tap into to improve situational awareness, facilitate coordination and take better informed decisions. However, processing these footprints, contextualizing and inferring over them presents several interesting challenges to the current state of Complex Event Processing methods. This article looks at challenges presented by an information system for perioperative process support and how contextualization and adequate tool support can provide the essential backdrop for meaningful inference.

    Key technological success features for a domain specific open software ecosystem for ambient assisted living
    (12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Mikalsen, Marius; Walderhaug, Ståle; Salvi, Dario; Hanssen, Geir Kjetil
    Ambient Assisted Living (AAL) is a domain with great potential for economic and societal impact. But market uptake of such solutions is so far limited because of market, standards and technology uncertainty. The businesses that will prevail are those that are cost effective. To support cost effective development of AAL solutions, domain specific open software ecosystems are being established. We developed a survey to investigate key technology success factors for such ecosystems. The survey was sent to 60 developers from a representative selection AAL development projects. 18 responded. Following a qualitative data analysis we found several key factors and features that must be in place to facilitate the success of such ecosystems. We found that given the nature of the AAL domain, characterised by divergent users, software and hardware, developers are seeking for support in three main areas. First, they want the artefacts available in the ecosystem to support relevant standards in the domain. Second, support for tracing artefacts available in the ecosystem to requirements (domain-fit) is needed. Third, they want support for developing, testing and emulating for complex usersoftware-hardware workflows in this distributed environment. The main obstacle that will scare away developers from the ecosystems is lack of documentation of the artefacts in the ecosystem. Second, not enough decoupled components, and finally, lack of proper search features. Finally, in order to be able to learn to use the artefacts, examples, scenarios and API documentation is necessary.

    Social network for elderly
    (12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Gulbrandsen, Simen Kind; Fikkan, Eirik; Grunt, Emil; Mehl, Kjetil; Shamsolketabi, Safoura; Singh, Jaspreet; Vrucinic, Miso; Mathisen, Bjørn Magnus; Kofod-Petersen, Anders
    Elderly's health is closely related to their level of social activity. Maintaining an active social life contributes to peoples' ability to live at home longer and enjoy an active and healthy life. Yet, as age progresses maintaining and expanding a social network can be challenging. The work presented here demonstrates a design and implementation of a social network system for elderly, including a recommender system, which will recommend relevant cultural and social events, and friends and acquaintances to enjoy these events with.

    The role of modeling in future innovative business and community information systems
    (12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Krogstie, John
    Future internet systems have a number of properties supporting new innovative business and community systems. Event-driven architectures (EDA) providing varied information to support collaborative decision-making enable more decisions to be made closer to the problem owner. The 'Internet of Things' (IoT) enables the Internet to reach out into the real world of physical objects. Mobile and collaborative applications and services utilizing information processing and process support enabled by sensor data from a vast numbers of connected and cheap devices and directly and indirectly from humans in control of these devices will change a number of markets. Future innovative business and community information systems will need to take this situation into account, addressing technological, methodological and conceptual challenges. This paper will focus on the latter, discussing in particular the potential role of model-based techniques and how to assess and improve the quality of models and modelling approaches in this setting using the SEQUAL framework.

    Drizzle: the RAIN prototype
    (12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Jaatun, Martin Gilje; Askeland, Christian Emil; Salvesen, Anders Emil
    Internet communities are moving to the Cloud, but in addition to the advantages regarding cost and convenience, this also means that cloud service providers are increasingly in a position to aggregate large amounts of personal data, which means that it is becoming prudent to develop mechanisms that can contribute to limiting the information available to providers. In this paper we present a prototype cloud security solution for protection against an “honest but curious” cloud provider. The solution is based on splitting up data and distributing it to multiple cloud providers, without encrypting the individual pieces. Our initial tests indicate that our solution is sufficiently efficient for normal use.

    A multiple platform approach to building a bus route information system for mobile devices
    (12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Andersstuen, Runar; Engell, Trond Bøe; Sætre, Rune; Gambäck, Björn
    The paper describes a multiple platform-based approach to creating a bus route information system for mobile devices. The system is context aware: users only need to tell the system (in natural language) where they wish to go, and the system takes care of the rest. The users are presented with a list of possible routes they can take to reach their desired destination. The results are also shown on a map that makes finding the bus stops very easy. In order to make the system available to as many users as possible, the architecture is client-server-based and relies on technology standards that are widely accepted and implemented, making it easily adaptable to new platforms. The application can be run on multiple platforms, with a minimal amount of calculations needed on the client side. The amount of data transfer between server and client is also kept to a minimum. The ability to run on multiple different platforms is achieved using technology such as HTML5, PhoneGap and Sencha Touch. The client's functionality includes a search function and a map view, as well as the ability to use bookmarks. The server handles most of the business logic and communicates with external services such as the natural language processing back-end and the server for real-time bus departure information updates.
