Autonomy, Heterogeneity and Trust in Mobile P2P environments

2007

Mobile P2P environments are emerging as a result of rapid expansion of portable terminals that are able to establish direct wireless communication links among themselves. These kinds of terminals are under the control of persons and allowing interactions between their terminals is subject to trust between the individuals and their desire to preserve various aspects of autonomy against each other. In this paper we relate the concepts of node autonomy, heterogeneity and trust with each other, defining also numeric measures for them. We also investigate what kind of interactions (such as transactions, file exchanges) are possible at certain heterogeneity, autonomy and trust level between the t…

Mobile cloud computing educational tool for image/video processing algorithms

2011

This paper shows the importance and benefit of coupling cloud computing with mobile especially due to power limitations that mobile devices exhibit. Moreover, the work done shows that mobile computing can be applied for educational purposes, where a tool for students termed Mobi4Ed is presented. This educational tool aims at exploiting the concept of cloud computing in the context of image and video processing, where students can assess several algorithms in real-time. Two possible system architectures are detailed, where one uses the cellular channel and the other uses the data channel. Consequently, one of the approaches is adopted and a detailed simulation is done where an Android client…

Mobile Electronic Commerce: Emerging Issues

2000

There are many definitions for Mobile Electronic Commerce (M-Commerce). We define M-Commerce as any type of transaction of an economic value having at least at one end a mobile terminal and thus using the mobile telecommunications network. The Wireless Application Protocol (WAP) plays an important role in m-commerce by optimizing Internet standards for the constraints of the wireless environment and thus bridging the gap between Internet and mobile world. Mobile Network Operators can play a major role in m-commerce by being strategically positioned between customers and content/service providers. In this paper we investigate the roles the operator can play in m-commerce and discuss respecti…

Developing Mobile Ontologies; Who, Why, Where, and How?

2007

The number of mobile subscribers in the world is soon reaching the three billion mark. According to the newest estimates, majority of the subscribers are already in the developing countries, whereas the number of subscribers in the industrialized countries is about to stagnate around one billion. Because especially in the developing countries the only access to Internet are mobile devices, developing high quality services based on them grows in importance. Ontologies are an important ingredient towards more complicated mobile services. In this paper we refine the taxonomy for mobile ontologies and discuss their creation, business models, maintenance and intellectual property rights (IPR).

Semantic place recognition for context aware services

2012

Extracting the meaning of the most significant places, which are frequently visited by a mobile user, is a relevant problem in mobile computing. Predicting semantic meaning of such places is useful in many areas. The problem of place semantic annotation of a user location can be challenging for service providers. Awareness of user activities is very important for development of personalized applications, which can be used in health care systems, living systems, etc. Predicting location of mobile users not only enables development of high quality location-based services and applications, but also improves resource reservation in wireless networks. In this research several solutions for seman…

Collaborative Mobile Clouds: An Energy Efficient Paradigm for Content Sharing

2018

On the way toward enabling efficient content distribution, reducing energy consumption and prolonging battery life of mobile equipment, an emerging paradigm, i.e., mobile cloud, which is based on content distribution, was proposed. As a mobile platform that is oriented toward content distribution, mobile cloud is also foreseen as an energy-efficient solution for future wireless networks. The benefits of using CMC for content distribution or distributed computing from social networking perspectives have been studied earlier. In this article, we first present the concepts of CMC and then discuss the energy-efficiency benefits from the system-level point-of-view as well as open challenges in d…

Theoretical Game Approach for Mobile Users Resource Management in a Vehicular Fog Computing Environment

2018

Vehicular Cloud Computing (VCC) is envisioned as a promising approach to increase computation capabilities of vehicle devices for emerging resource-hungry mobile applications. In this paper, we introduce the new concept of Vehicular Fog Computing (VFC). The Fog Computing (FC) paradigm evolved and is employed to enhance the quality of cloud computing services by extending it to the edge of the network using one or more collaborative end-user clients or near-user edge devices. The VFC is similar to the VCC concept but uses vehicles resources located at the edge of the network in order to serve only local on-demand mobile applications. The aim of this paper is to resolve the problem of admissi…

Service Provisioning with Multiple Service Providers in 5G Ultra-dense Small Cell Networks

2015

In this work, a game theoretical approach for addressing the virtual network service providers (NSPs), small cell provider (SCP) and user interaction in heterogenous small cell networks is presented. In particular, we consider the users can select the services of different NSPs based on their prices. The NSPs have no dedicated hardware and need to rent from the SCP in term of radio resources, e.g., small cell base stations (SBSs) in order to provide satisfied services to the users. Due to the fact that the selfish parties involved aim at maximizing their own profits, a hierarchical dynamic game framework is presented to address interactive decision problem. In the lower-level, a Stackelberg…

Change and Control Paradoxes in Mobile Infrastructure Innovation: The Android and iOS Mobile Operating Systems Cases

2012

The advent of the smart phone as a highly complex technology has been accompanied by mobile operating systems (OS), large communities of developers, diverse content providers, and increasingly complex networks, jointly forming digital infrastructures. The multi-faceted and relational character of such digital infrastructures raises issues around how change and control can be conceptualized and understood. We discuss how change and control are paradoxically related in digital infrastructures and how they affect the evolution of such infrastructures. We examine these paradoxes by examining the change in, and competition between, two mobile operating systems: Apple's iOS and Google's Android a…
