A Note on the Local Minimum Problem in Wireless Sensor Networks

2013

The Local Minimum Problem occurs in geographic routing scenarios. In this paper two solutions to this problem for certain network topologies are proposed. By using the notion of virtual coordinates a theoretical and a practical constructions are presented. A distributed algorithm for the practical approach is proposed.

CiNetView - Graphic Interface for Wireless Sensor Network Deployment and Monitoring

2010

Reliable communication is crucial for successful deployment of a wireless sensor network. Many environmental factors can affect the performance of radio links, and the deployment of a network without real-time information about link qualities can be a demanding task. This paper describes the CiNetView application that is intended to support the deployment and monitoring of wireless sensor network. CiNetView is based on diagnostic information collected by sensor nodes, and it allows the user to see a graphical presentation of the network topology and to monitor the network diagnostic information in real time.

Business models and opportunity creation: How IT entrepreneurs create and develop business models under uncertainty

2015

How can entrepreneurs develop business models for markets in which the technology is constantly changing-or create business models for markets that do not exist? These are fundamental questions for information technology IT entrepreneurs, and for information systems IS scholars who seek to develop a theoretical understanding of business models. The case study presented in this paper addressed these questions, demonstrating how a small software firm developed its business model over a 15-year period in cloud gaming markets. Based on the empirical findings, a preliminary theoretical model is presented. The aim of the model is to increase scholarly understanding of how business models are crea…

Systematic literature review of E-learning capabilities to enhance organizational learning

2021

AbstractE-learning systems are receiving ever increasing attention in academia, business and public administration. Major crises, like the pandemic, highlight the tremendous importance of the appropriate development of e-learning systems and its adoption and processes in organizations. Managers and employees who need efficient forms of training and learning flow within organizations do not have to gather in one place at the same time or to travel far away to attend courses. Contemporary affordances of e-learning systems allow users to perform different jobs or tasks for training courses according to their own scheduling, as well as to collaborate and share knowledge and experiences that res…

Framework Towards a Virtual Tool for the Front-End of Employee-Driven Innovation in Healthcare

2017

This paper combines entrepreneurial behaviour and service innovation in order to investigate the use of the Idea Window; a virtual tool planned for employee-driven service development in a healthcare organisation. The empirical study investigates the tool used as a method for supporting employees' collaborative knowledge sharing in front-end of innovation in two study cases. Particularly, the research findings focus on how the virtual tool can be used for tackling the unknown - tacit knowledge, hidden possibilities, and initiatives in the context. The results are based on Idea Window entries and survey data collected in a Finnish hospital ward.

Mobile e-Services

2015

E-services are services delivered over the Internet. Such services have different proper- ties and dimensions, e.g. targeting different sectors, being accessible through different channels, or intended for frequent or infrequent use. Throughout this article we address e-services from a mobility perspective. We do this by 1) positioning mobile e-services within the research field; 2) reviewing related work on mobile e-services; and 3) present- ing and examining existing difficulties and opportunities when combining mobility and e-services. We see mobile e-services as the next generation of internet-based services and discuss important focus areas and future directions, giving extra notion to…

Exploration of Location-Based Services Adoption

2011

The purpose of this chapter is to explore aspects of user perceptions of their use of location-based services. As mobile technologies become more ubiquitous in the general population, it is reasonable to assume that individuals will consume services and software to enhance their aspirations and entertainment desires. This study begins by constructing a location-based service prototype simulation. It then conducts an experiment and analysis based on the Unified Theory of Acceptance and Use of Technology (UTAUT) model. A survey was developed to extract usage information from participants, followed by an analysis of the results using PLS. The analysis shows significant indicators that suggest …

Universal Design of ICT for Emergency Management from Stakeholders’ Perspective

2020

While Universal Design principles have been adopted in many areas to ensure that products and services are usable for the broadest possible diversity of users, there is still an open area when it comes to the emergency management domain. This article aims at providing a systematic overview of the current state of the emerging research field of Universal Design of Information and Communication Technology (ICT) for Emergency Management, and to highlight high-impact research opportunities to ensure that the increasing introduction of ICT in Emergency Management can contribute to removing barriers instead of adding more barriers, in particular for the elderly and people with disabilities. A sys…

Verbal and visual representations in task redesign: how different viewpoints enter into information systems design discussions

2005

We explore an important phase of information systems design (ISD), namely task redesign, and especially how different viewpoints enter into the dis- cussions. We study how one particular visual representation, a process diagram, is interpreted and how alternative, even competing, representations are produced verbally. To tie the visual and verbal representations and the representational prac- tices to wider social practices, we develop and use the Extended Three-dimen- sional Model of discourse. Visual representations emerged as focal in bringing in the different viewpoints and as reference points for discussions. Our model pro- vided a focused and powerful means to unveil for the outside r…
