A Double Auction Mechanism for Virtual Resource Allocation in SDN-based Cellular Network

2016

The explosively growing demands for mobile traffic service bring both challenges and opportunities to wireless net- works, among which, wireless network virtualization is proposed as the main evolution towards 5G. In this paper, we first propose a Software Defined Network (SDN) based wireless virtualization architecture for enabling multi-flow transmission in order to save capital expenses (CapEx) and operation expenses (OpEx) significantly with multiple Infrastructures Providers (InPs) and multiple Mobile Virtual Network Operators (MVNOs). We for- mulate the virtual resource allocation problem with diverse QoS requirements as a social welfare maximization problem with transaction cost. Due…

Resource Allocation and Computation Offloading for Wireless Powered Mobile Edge Computing

2022

In this paper, we investigate a resource allocation and computation offloading problem in a heterogeneous mobile edge computing (MEC) system. In the considered system, a wireless power transfer (WPT) base station (BS) with an MEC sever is able to deliver wireless energy to the mobile devices (MDs), and the MDs can utilize the harvested energy for local computing or task offloading to the WPT BS or a Macro BS (MBS) with a stronger computing server. In particular, we consider that the WPT BS can utilize full- or half-duplex wireless energy transmission mode to empower the MDs. The aim of this work focuses on optimizing the offloading decision, full/half-duplex energy harvesting mode and energ…

Mobile communication and work practices in knowledge-based organizations

2005

This paper examines the role of mobile communication, mobile tools and work practices in the context of organizations, especially knowledge-based organizations. Today, organizations are highly complex and diverse. Not surprisingly, various solutions to incorporating mobile tools and mobile communication in organizations have been devised. Challenges to technological development and research on mobile communication are presented.

Teknologisten laitteiden ja sovellusten käyttö vanhustyössä : työn piirteiden ja yksilötekijöiden vaikutusten tarkastelua

2021

Artikkelissa tarkastellaan vanhustyössä käytettyjen teknologisten laitteiden ja sovellusten yleisyyttä ja toisaalta niiden käytön riippuvuutta työhön liittyvistä ja yksilöllisistä tekijöistä. Teknologian käyttö tiivistyy kolmeen pääulottuvuuteen: mobiiliin hoivateknologiaan, toimistoteknologiaan ja viihdeteknologiaan. Käyttöä määritti ensi sijassa sektori ja toimipaikan tyyppi, ei niinkään työntekijän yksilölliset piirteet. Viitteitä on myös siitä, että työn teknologisoituminen etenee ylhäältä alaspäin ja on yhteydessä nimenomaan työn rakenteellisiin piirteisiin. New technologies and applications are expected to cut expenditures, ease the workload of employees, and improve the quality of el…

Young Elderly and Digital Coaching : A Quantitative Intervention Study on Exercise Self-Efficacy

2020

Sport and wellness technology devices are becoming an increasingly relevant topic when discussing health and wellness. This study focuses on the use of a “digital coach”, within a specific population, young elderly people. This research explored how the use of a digital coach would affect self-efficacy related to physical activity and exercise among young elderly. Thisquantitative intervention study provided a digital coaching device to a group of young elderly people ranging from 61-78 in age for 10-weeks. It was found that a digital coach may be useful for this population, particularly in increasing their perceived confidence in exercising independently. However, the participants’ percept…

Changes in the Use Intention of Digital Wellness Technologies and Its Antecedents Over Time : The Use of Physical Activity Logger Applications Among …

2021

Physical inactivity has become a prevalent problem among elderly people. Although digital wellness technologies have been proposed as one promising solution to it, our understanding on the antecedents of the acceptance and use of these technologies among elderly people remains limited. In this study, our objective is to promote this understanding by examining the potential changes in the use intention of digital wellness technologies and its antecedents over time in the case of the young elderly segment and physical activity logger applications. We base this examination theoretically on UTAUT2 and empirically on survey data that is collected from 99 Finnish young elderly users of a physical…

A Follow-Up On The Changes in the Changes in the Use Intention of Digital Wellness Technologies and Its Antecedents Over Time : The Use of Physical A…

2021

This study aims to further promote the understanding of the antecedents of the acceptance and use of digital wellness technologies among elderly people through a follow-up to our two prior studies, one which examines the potential longer-term temporal changes in the use intention of digital wellness technologies and its antecedents in the case of the young elderly segment and physical activity logger applications. We base this examination theoretically on UTAUT2 and empirically on survey data that is collected from 92 Finnish young elderly users of a physical activity logger application in three subsequent time points and analysed with partial least squares structural equation modelling (PL…

Forming Sustainable Physical Activity Programs Among Young Elderly : A Combined ELM & UTAUT Approach

2021

There is consensus in health studies that regular physical activities of sufficient intensity and duration contribute to better health both in the short and long term. In an ongoing research program, we focus on getting the young elderly, the 60-75 years age group, to adopt and include physical activities as part of their daily routines. One reason for addressing young elderly is large numbers – in Finland health care costs for the elderly was 3.7 B€ in 2019 and will increase dramatically if the young elderly group is in bad shape when they reach the 75+ age group. We are finding out that systematic physical activities can serve as preventive health care for the young elderly. We are also l…
