Exploiting Mobile Ad Hoc Networking and Knowledge Generation to Achieve Ambient Intelligence  [PDF]
Anna Lekova
Applied Computational Intelligence and Soft Computing , 2012, DOI: 10.1155/2012/262936
Abstract: Ambient Intelligence (AmI) joins together the fields of ubiquitous computing and communications, context awareness, and intelligent user interfaces. Energy, fault-tolerance, and mobility are newly added dimensions of AmI. Within the context of AmI the concept of mobile ad hoc networks (MANETs) for “anytime and anywhere” is likely to play larger roles in the future in which people are surrounded and supported by small context-aware, cooperative, and nonobtrusive devices that will aid our everyday life. The connection between knowledge generation and communication ad hoc networking is symbiotic—knowledge generation utilizes ad hoc networking to perform their communication needs, and MANETs will utilize the knowledge generation to enhance their network services. The contribution of the present study is a distributed evolving fuzzy modeling framework (EFMF) to observe and categorize relationships and activities in the user and application level and based on that social context to take intelligent decisions about MANETs service management. EFMF employs unsupervised online one-pass fuzzy clustering method to recognize nodes' mobility context from social scenario traces and ubiquitously learn “friends” and “strangers” indirectly and anonymously. 1. Introduction Ambient intelligence (AmI) is emerging as a new research discipline joining the fields of ubiquitous computing and communications, context-awareness, and intelligent user interfaces. The paradigm is also known as “pervasive computing”, “things that think”, “ubiquitous computing”, and so forth. Energy, fault-tolerance, and mobility are newly added dimensions of the AmI [1]. AmI places people and social contexts at the centre, while the information and communication technologies as well as network context go to the background. The new AmI paradigm is made possible by the convergence of low-cost sensors, embedded processors, and wireless ad hoc networks in new generation industrial digital products and services. Mobile ad hoc networks (MANETs) are multihop wireless networks without fixed infrastructure, formed by mobile nodes. The connection between knowledge generation and mobile ad hoc networks will be symbiotic—knowledge generation will utilize the wireless ad hoc networking to perform their communication needs, and MANETs will utilize knowledge generation to enhance their network services. Current mobile devices, which go together with us anywhere and at anytime, are the most convenient tools to help us in ubiquitous computing, that is, to intermediate between us and our surroundings in an unobtrusive
Knowledge Networking for Family Planning: The Potential for Virtual Communities of Practice to Move Forward the Global Reproductive Health Agenda  [cached]
Megan O’Brien,Catherine Richey
Knowledge Management & E-Learning : an International Journal , 2010,
Abstract: This paper highlights experience from five years of using virtual communication tools developed by the World Health Organization Department of Reproductive Health and Research (WHO/RHR) and its partners in the Implementing Best Practices (IBP) in Reproductive Health Initiative to help bridge the knowledge-to-practice gap among family planning and reproductive health professionals. It explores how communities of practice and virtual networks offer a unique low-cost way to convene public health practitioners around the world to share experiences. It offers examples of how communities of practice can contribute to the development and dissemination of evidence-based health information products, and explores the potential for online networking and collaboration to enhance and inform program design and management. The paper is intended to inform the reproductive health community, as well as others working in health and development, of the potential for using virtual communities of practice to work towards achieving common goals and provide some examples of their successful use.
Sports Video Analysis: Semantics Extraction, Editorial Content Creation and Adaptation  [cached]
Changsheng Xu,Jian Cheng,Yi Zhang,Yifan Zhang
Journal of Multimedia , 2009, DOI: 10.4304/jmm.4.2.69-79
Abstract: Advances in computing, networking, and multimedia technologies have led to a tremendous growth of sports video content and accelerated the need of analysis and understanding of sports video content. Sports video analysis has been a hot research area and a number of potential applications have been identified. In this paper, we summarize our research achievement on semantics extraction and automatic editorial content creation and adaptation in sports video analysis. We first propose a generic multi-layer and multi-modal framework for sports video analysis. Then we introduce several mid-level audio/visual features which are able to bridge the semantic gap between low-level features and high-level understanding. We also discuss emerging applications on editorial content creation and content enhancement/adaptation in sports video analysis, including event detection, sports MTV generation, automatic broadcast video generation, tactic analysis, player action recognition, virtual content insertion, and mobile sports video adaptation. Finally, we identify future directions in terms of research challenges remained and real applications expected.
Generalized Virtual Networking: an enabler for Service Centric Networking and Network Function Virtualization  [PDF]

Computer Science , 2014,
Abstract: In this paper we introduce the Generalized Virtual Networking (GVN) concept. GVN provides a framework to influence the routing of packets based on service level information that is carried in the packets. It is based on a protocol header inserted between the Network and Transport layers, therefore it can be seen as a layer 3.5 solution. Technically, GVN is proposed as a new transport layer protocol in the TCP/IP protocol suite. An IP router that is not GVN capable will simply process the IP destination address as usual. Similar concepts have been proposed in other works, and referred to as Service Oriented Networking, Service Centric Networking, Application Delivery Networking, but they are now generalized in the proposed GVN framework. In this respect, the GVN header is a generic container that can be adapted to serve the needs of arbitrary service level routing solutions. The GVN header can be managed by GVN capable end-hosts and applications or can be pushed/popped at the edge of a GVN capable network (like a VLAN tag). In this position paper, we show that Generalized Virtual Networking is a powerful enabler for SCN (Service Centric Networking) and NFV (Network Function Virtualization) and how it couples with the SDN (Software Defined Networking) paradigm.

Improving Availability Using Mobile Agents in Wireless Networking
Michael Hosein,Aleema Khan
Journal of Engineering and Applied Sciences , 2012, DOI: 10.3923/jeasci.2010.84.90
Abstract: The rapid development of the Internet and networking technologies like 802.11n as well as Gigabit Ethernet and FTTH and the related technologies have led to an expansion of shared services and resources. These resources e.g., files can be accessed from desktops, laptops, workstations, pdas, cell phones, televisions in many cases without regard to location and at very good speeds. Mobile agents can play an important role in allowing anytime/anywhere access. This study attempts to investigate the use of mobile agents as a means of improving data availability over a wireless network. Resources were distributed using the static client/server model as well as the dynamic mobile agent model and the results showed the viability of the mobile agents approach.

Computer Science , 2010,
Abstract: The rapid development of wireless technology, the extensive use of mobile phones and the availability of location information are facilitating personalized location-based applications. Easy to carry, easy to use and easy to buy, smart phones with certain software are of great advantage. Consequently, mobile social networking (MSN) systems have emerged rapidly, being a revolution for our everyday life. Based on the analysis of general requirements of MSN and location-based services (LBS), this paper presents the design of iZone, a mobile social networking system, as well as a prototype implementation. This platform exploits mobile GIS (Geographic Information Systems), LBS and J2ME technologies, combining geographical data to display map on mobile phones. It can provide a number of social networking services via smartphones.
Knowledge Spillovers: The Virtual Generation  [cached]
Marcela C. Revilla E,Sebastian Kelle
Communications of the IBIMA , 2008,
Abstract: This paper highlights features of the Web 2.0 and its evolution into Web Societies, the Virtual Generation, or Generation V’s, major contrivance for knowledge diffusion (knowledge spillovers). Web 2.0 has set the bases for a highly intensive environment for knowledge creation and collaboration processes, with important implications for the nature of technological change. This work aims to present a documented, exploratory rather than explanatory study, based on descriptive definitions of the evolution of Web Societies and their implications for knowledge dissemination, on which to later base an empirical analysis.
Adaptive Semantic Interoperability Strategies for Knowledge Based Networking  [cached]
Song Guo,John Keeney,David Lewis,Declan O’Sullivan
Journal of Software , 2009, DOI: 10.4304/jsw.4.8.808-820
Abstract: Knowledge-based networking involves the forwarding of messages across a network based on semantics of the data and associated metadata of the message content. However such systems typically assume a common semantic model underpinning the routing which limits their ability to cope with heterogeneity. In contrast, the authors have developed a semantic-based publish/subscribe system that is unique in allowing several semantic models to support routing. This paper examines the content heterogeneity problem in a Knowledge-based Network (KBN) implementation and evaluates a mechanism for efficiently and dynamically loading ontological mappings for use with distributed and heterogeneous knowledge-based applications. It compares a number of strategies that use pre-existing semantic mapping information stored in KBN routers. Evaluation results show that this mechanism can effectively solve the heterogeneity problem.
The Digital, the Virtual and the Naming of Knowledge  [cached]
Darren Jorgensen
Fibreculture Journal , 2007,
Abstract: Amidst changing regimes of disciplinarity, the digital has become a term used to delineate a mode of knowledge and educational methodology. Its currency comes from the technologies that share its name, yet the territory that it marks is much greater than this, referring to the cultural, economic and social. The digital is too proximate to the technological to adequately account for this territory. Instead, I argue for radical interventions in the naming of knowledge in order to defamiliarise the digital. Different accounts of the virtual by Pierre Lévy, Katherine Hayles and David Summers suggest that this term establishes a greater range of enquiry and contestation. The virtual is but one alternative to the digital as a means by which new disciplines, methodologies and pedagogies might be constituted.
