Broadband Internet Access via Multi-Hop Wireless Mesh Networks: Design, Protocol and Experiments
2010
Published version of an article from the journal: Wireless Personal Communications. The original publication is available at Spingerlink. http://dx.doi.org/10.1007/s11277-009-9907-9 While bandwidth for Internet access in urban areas is steadily increasing in recent years, many rural areas are still suffering from the effect of the digital divide. This paper presents a broadband Internet access paradigm developed in the context of the ADHOCSYS project, which was financed by the European Commission under the 6th Framework Program Information and Society Technologies, within the strategic objective of Broadband for All. Aiming at providing reliable Internet access in rural and mountainous regi…
Techno-economical inspection of high-speed Internet connection for trains
2008
Some attractive service scenarios for Railways' Intelligent Transport Systems (RITS) in three different user segments, that is, passengers, freight companies and train operator's in-house customers, are presented. The case study covers the analysis of customer needs and techno-economic evaluations. The analysis indicates that Flash-OFDM technology provides promising pre-stage solution for the train connections in Finland. Also, the WiMAX-based high-speed Internet access for passengers may be profitable in the most heavily operated railway leg in Finland. The sensitivity analysis shows that the most crucial parameters for the case are `User Share', `Average Revenue per User' and `WiMAX Cell …
Measuring Repurchase Intention on Fashion Online Shopping
2020
The internet has become one of many ways for consumers to shop. With the rapid development of internet connection, online shopping has become increasingly popular around the world. All forms of conveniences available through online businesses have lured consumers to switch from offline shopping to online slowly. This research emphasizes the influence of e-service convenience on customer satisfaction, perceived service value, and repurchase intention on fashion online shopping websites in Surabaya. The sample is taken from 115 Surabaya respondents. The sampling technique uses a non-random sampling technique. The analytical method used is the partial least square (PLS). The results show that …
Inter-provider AAA and Billing of VoIP Users with Token-based Method
2007
With the increasing popularity of wireless LAN technology, providers of real-time voice over IP (VoIP) services, known as voice service providers (VSP), are asking for roaming solutions and AAA (Authentication, Authorization and Accounting) methods that allow users to use their services from any available public Internet access network. In this paper we propose an AAA and billing architecture that allows users of VSPs to have access to the Internet from wired and wireless access networks provided by both traditional carriers, such as 3G providers, and wireless local access network (WLAN) providers. We propose a token-based AAA method that allows users of VoIP services to have their VSPs as …
Grounded Analytic Research: Building Theory from a Body of Research
2012
Track II: Recent Developments in Inductive Research Methods; International audience; In this paper, we present Grounded Analytic Research (GAR) as a method to build theory by synthesizing empirical findings from multiple studies that has been conducted by a single researcher. GAR incorporates concepts from grounded theory, analytic research and systematic literature review. The method was applied in a doctoral dissertation work to build the theoretical concept of Demand Sustainability of public Internet access in the context of bridging the digital divide. We describe GAR and compare it with existing theory building methods that are similar to it in epistemology and ontology.
Crowdfunding in Africa: Opportunities and Challenges
2020
AbstractThe chapter presents the current state of crowdfunding research and practice in Africa while outlining opportunities and challenges associated with them. Conditions of growing popularity of digital and mobile finance, low penetration of traditional financial institutions, and a long cultural heritage of communal mutual support may enhance crowdfunding uptake. On the other hand, conditions of unclear regulation, relatively low levels of internet access, and societies characterized by low social trust may all hinder crowdfunding uptake. Accordingly, African crowdfunding is at its infancy and involves transitory hybrid practices of early adoption, often involving reliance on foreign co…
Deep learning model deploying on embedded skin cancer diagnostic device
2020
The number of research papers, where neural networks are applied in medical image analysis is growing. There is a proof that Convolutional Neural Networks (CNN) are able to differentiate skin cancer from nevi with greater accuracy than experienced specialists on average (sensitivity 82% and 73% accordingly).1 Team's latest research2 allows achieving even greater accuracy, by using specific narrow-band illumination. Nevertheless, the overall probability of early skin cancer detection depends on the availability of diagnostic tools. If screening tools will be available to a high number of general practices, the chance of disease detection will increase. The previous research3 shows that scala…
A comparison study of evolutive algorithms for solving the partitioning problem in distributed virtual environment systems
2004
Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environment (DVE) systems very common nowadays. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3D avatars) to the servers in the system. In this paper, we present a comparison study of different modern heuristics for solving the partitioning problem in DVE systems, as an alternative to the ad hoc heuristic proposed in the literature. Performance evaluation results show that some…
A Comparison Study of Modern Heuristics for Solving the Partitioning Problem in Distributed Virtual Environment Systems
2003
Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environment (DVE) systems very common nowadays. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3-D avatars) to the servers in the system. In this paper, we present a comparison study of different modern heuristics for solving the partitioning problem in DVE systems, as an alternative to the ad-hoc heuristic proposed in the literature. Performance evaluation results show that som…
A REST-based publish/subscribe platform to support things-to-services communications
2013
The term “Internet of Things” has been used widely in recent years, bringing up a grand idea of connecting physical objects with one another through both wired and wireless networks. Maturity of the Internet Protocol has pushed 21st century communications between devices to go all-IP, which includes everyday objects. Many new services are deployed in the “cloud”, utilising the Internet infrastructure and the Web, and information from everyday objects can play an important role. This paper presents an information integration platform which enables everyday objects to communicate with Internet services based on event-driven service-oriented architecture paradigm. A proof-of-concept prototype …
