Towards integrated operations for ships
2013
Maritime customers will benefit greatly from integrated operations between ship and shore. It requires integrating diverse information services within a variety of communication environments, which is a complex task. The common approach to dealing with complex tasks is to use a divide-and-conquer policy and solve problems independently. Since there are mainly two challenges involved - interoperability among heterogeneous applications and connectivity through difficult maritime networks, to handle them separately has become useful. While interoperability and connectivity solutions work well individually, if we put them together in the maritime context, problems arise. We b services based int…

Energy Efficiency Evaluation of Cellular Networks Based on Spatial Distributions of Traffic Load and Power Consumption
2013
Energy efficiency has gained its significance when service providers' operational costs burden with the rapidly growing data traffic demand in cellular networks. In this paper, we propose an energy efficiency model for Poisson-Voronoi tessellation (PVT) cellular networks considering spatial distributions of traffic load and power consumption. The spatial distributions of traffic load and power consumption are derived for a typical PVT cell, and can be directly extended to the whole PVT cellular network based on the Palm theory. Furthermore, the energy efficiency of PVT cellular networks is evaluated by taking into account traffic load characteristics, wireless channel effects and interferen…
Investigating teachers motivation to use ICT tools in higher education
2015
There are a lot of information and communication technology (ICT) tools for education, but the motivation to use those varies from teacher to teacher. In this paper we present results of an international survey on teachers' use of ICT tools in education. The purpose of the survey was to find out what motivates teachers to use ICT tools in the context of teaching. The survey also intended to reveal which tools are used as well as the needs and requirements that are not covered by the existing tools. Most of the 45 respondents suggested that the integration of tools depends on how well they fit into the learning and teaching process and how easy it is to integrate them. The first category of …
Media Delivery to Remote Renderers Controlled by the Mobile Phone
2009
In today's content delivery solutions, service delivery and control are still tightly coupled, a service typically being delivered to the same device that controls the session. We present a solution that was designed with the goal to decouple service control and delivery. Using our approach, multimedia streaming services can be delivered to off-the-shelf DLNA devices in visited networks. The service provider receives information about the remote media player and access environment via a mobile phone. Proximity technologies (e.g. barcodes, NFC) of the control device are used for the exchange of required credentials. This paper describes a typical scenario and our prototype implementation.

Using Multi-touch Multi-user Interactive Walls for Collaborative Active Learning
2019
Active learning has been advocated for enhancing students’ higher order cognition in social constructivist learning settings. However, with the increasing use of student-owned computing devices in face-to-face classrooms, there are risks of limited student-student interactions. Students are likely to be distracted by non-academic activities, hence becoming inactive with regards to the learning tasks. This article presents a technology enhanced learning approach, in which students perform group learning tasks using shared digital workspace while in a physical classroom. The workspace comprises of a 9-m wide screen wall with multi-touch, multi-user interfaces supporting multimodal interaction…

Delivering Services to Residential Appliances by Utilizing Remote Resource Awareness
2008
Service providers are nowadays offering a variety of services, and in particular multimedia content delivery. Besides, consumer appliances are increasingly becoming digitalized including support for communication networks. However, it is difficult, and in many cases impossible, to use these services with standard consumer appliances, such as TV and media player devices. Rather, usage is often restricted so that they can only be accessed through web browsers from PCs, mobile phones and similar terminals. This is unfortunate, because dedicated consumer appliances are often better suited to handle the content and thereby give consumers a better experience. Within this paper, three design appro…
Towards a relation oriented service architecture
2010
Over the past three decades, the Internet has evolved from a point to point, open, academic network to an applications and services oriented critical infrastructure. The Internet has become a vital component of society today, from its simple origin as an academic research project. During this transition, numerous applications and usages of the network emerged that cannot be efficiently implemented by adhering to the original design tenets of the Internet. Some of the tenets have been broken, others diluted and new ones are emerging to accommodate new paradigms. Moreover, applications and services have been moving slowly but consistently towards a uniform model based on Service Oriented Appr…

Using SIP Presence for Remote Service Awareness
2008
Residential networks usually protect its devices and services behind firewalls and use private IP addresses. Therefore, appliances within a residential network cannot be discovered and utilized from external networks by standardized technologies as UPnP. In this paper, we present our concept of “Service Presence”, based on the 3GPP Presence Service that makes the service presence information remotely discoverable.
Remote service usage through SIP with multimedia access as a use case
2007
The IP Multimedia Subsystem is under deployment, as an IP-based service control and access infrastructure, but how it interconnects with residential appliances is currently unclear. With IMS access for the residential appliances they can be used as both service consumers and service providers. In this paper we present a protocol which allows residential services to be remotely invoked, through the IMS, and consumed in a different network, along with a prototype implementation and early results. With our protocol services of two distinct service protocol systems can cooperate.
Ethical issues of gamified ICT tools for higher education
2015
A recent trend in e-learning is the development of ICT tools with game elements to increase the motivation of using new technology in teaching and learning. In most cases, games possess different ethical constraints than regular e-learning systems. For this reason, additional implications and issues deriving from the combined development of games and e-learning technology have to be considered. During the development process of gamified e-learning systems as well as during the use of gamified ICT tools in education special attention must be paid to ethical constraints. This paper presents ethical considerations as to how to properly motivate teachers to adopt new technology in their teachin…

Towards a layer-less network architecture — A case from Wireless Sensor Networks
2011
Ad hoc and Wireless Sensor Networks (WSNs) form a challenging domain for existing network protocols and paradigms to fit into. The traditional models conceived for wired networking and adapted for wireless and mobile environments provide an inefficient and ungraceful outcome when exercised against highly dynamic and highly mobile nature of ad hoc wireless sensor networks. Efforts are being made to tweak existing (and sometimes create from scratch) principles and models that can provide a concrete framework for such newer paradigms. The momentum of the traditional layered architecture carried over from the wired networks to infrastructure based wireless networks pushes the same approaches as…

Virtualization of Remote Devices and Services in Residential Networks
2009
Lately solutions for remote access for residential services have been proposed. However, these solutions require modifications to the service controllers. In addition, remote access adds complexity to the client application. We propose here a solution for decoupling remote access from the client itself with an entity that creates virtual instances of remote services in a local network. Thereby, clients will be able to discover the virtual instance and use it. Moreover, client applications do not need to distinguish between local and remote services hence reducing complexity.
Phone-Controlled Delivery of NGN Services into Residential Environments
2008
The horizontally layered architecture of the IMS/NGN standards family enables the delivery of services independent of access network and requesting device. In this article, the authors propose a further separation of service control and delivery, allowing the requesting device - in particular a user's mobile phone - to invite other devices (we will focus on DLNA appliances) into the service delivery, enhancing both user experience and service design flexibility. The proposed solution builds on exploiting proximity technologies (e.g. barcodes, NFC) for pairing the control device with a remote environment. Motivated by scenarios, the architecture concepts are explained and a prototype that wa…
Rethinking practices of assessment for learning: Tablet technology supported assessment for learning mathematics
2013
This article discusses assessment for learning in mathematics subjects. It is challenging for teachers of large classes to regularly assess students' mathematics in order to help them improve their learning achievement. Given the complexity of assessing and providing feedback for learning, a new approach to assessment for learning was suggested. Media tablet technology supported assessment processes were devised and user studies were conducted in Norway and Rwanda. There are indications that students like to be involved in assessing each other's mathematics work. Students expect to get learning gains by providing and obtaining feedback to/from their peers using technology supported tools.
