This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An intermittently connected network (ICN) is defined as a mobile network thatuses cooperation between nodes to facilitate communication. This cooperation consistsof nodes carrying messages from other nodes to help deliver them to their destinations. An ICN does not require an infrastructure and routing information is notretained by the nodes. While this may be a useful environment for message dissemination, it creates routing challenges. In particular, providing satisfactory deliveryperformance while keeping the overhead low is difficult with no network infrastructureor routing information. This dissertation explores solutions that lead to a highdelivery probability while maintaining a low overhead ratio. The efficiency of messagefragmentation in ICNs is first examined. Next, the performance of the routingis investigated when erasure coding and network coding are employed in ICNs. Finally,the use of social networking in ICNs to achieve high routing performance isconsidered. The aim of this work is to improve the better delivery probability while maintaininga low overhead ratio. Message fragmentation is shown to improve the CDF ofthe message delivery probability compared to existing methods. The use of erasurecoding in an ICN further improve this CDF. Finally, the use of network coding wasexamined. The advantage of network coding over message replication is quantified in terms of the message delivery probability. Results are presented which show thatnetwork coding can improve the delivery probability compared to using just messagereplication.

Download or read book Connected Parenting written by Jai Mackenzie and published by Bloomsbury Publishing. This book was released on 2023-02-23 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changing practices and perceptions of parenthood and family life have long been the subject of intense public, political and academic attention. Recent years have seen growing interest in the role digital media and technologies can play in these shifts, yet this topic has been under-explored from a discourse analytical perspective. In response, this book's investigation of everyday parenting, family practices and digital media offers a new and innovative exploration of the relationship between parenting, family practices, and digitally mediated connection. This investigation is based on extensive digital and interview data from research with nine UK-based single and/or lesbian, gay or bisexual parents who brought children into their lives in non-traditional ways, for example through donor conception, surrogacy or adoption. Through a novel approach that combines constructivist grounded theory with mediated discourse analysis, this book examines connected family lives and practices in a way that transcends the limiting social, biological and legal structures that still dominate concepts of family in contemporary society.

Download or read book Digital and Social Media Marketing written by Nripendra P. Rana and published by Springer Nature. This book was released on 2019-11-11 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines issues and implications of digital and social media marketing for emerging markets. These markets necessitate substantial adaptations of developed theories and approaches employed in the Western world. The book investigates problems specific to emerging markets, while identifying new theoretical constructs and practical applications of digital marketing. It addresses topics such as electronic word of mouth (eWOM), demographic differences in digital marketing, mobile marketing, search engine advertising, among others. A radical increase in both temporal and geographical reach is empowering consumers to exert influence on brands, products, and services. Information and Communication Technologies (ICTs) and digital media are having a significant impact on the way people communicate and fulfil their socio-economic, emotional and material needs. These technologies are also being harnessed by businesses for various purposes including distribution and selling of goods, retailing of consumer services, customer relationship management, and influencing consumer behaviour by employing digital marketing practices. This book considers this, as it examines the practice and research related to digital and social media marketing.
Download or read book Interconnecting the Network of Networks written by Eli M. Noam and published by MIT Press. This book was released on 2001-08-17 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the transformation of telecommunications from national network monopolies to a new system, the "network of networks," and the glue that holds it together, interconnection. By their very nature, monopoly-owned networks provided a small number of standardized, nationwide services. Over the past two decades, however, new forces in the world economy began to unravel this traditional system. The driving force behind the change was the shift toward an information-based economy. Especially for large organizations, the price, control, security, and reliability of telecommunications became variables requiring organized attention. Thus, monopoly began to give way to the "network of networks," the foundation of today's telecommunications and Internet infrastructure. Taking a broad, multidisciplinary perspective Eli Noam discusses the importance and history of interconnection policy, as well as recent policy reforms both within the United States and around the globe. Other important topics he discusses include interconnection prices, the unbundling of interconnection, and the technology of interconnection. He concludes with an examination of social and policy issues, including the free flow of content, universal service and privacy protection, and the future of telecommunications.

Download or read book Virtualpolitik written by Elizabeth Mathews Losh and published by MIT Press. This book was released on 2009 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Government media-making, from official websites to whistleblowers' e-mail, and its sometimes unintended consequences. Today government agencies not only have official Web sites but also sponsor moderated chats, blogs, digital video clips, online tutorials, videogames, and virtual tours of national landmarks. Sophisticated online marketing campaigns target citizens with messages from the government--even as officials make news with digital gaffes involving embarrassing e-mails, instant messages, and videos. In Virtualpolitik, Elizabeth Losh closely examines the government's digital rhetoric in such cases and its dual role as mediamaker and regulator. Looking beyond the usual focus on interfaces, operations, and procedures, Losh analyzes the ideologies revealed in government's digital discourse, its anxieties about new online practices, and what happens when officially sanctioned material is parodied, remixed, or recontextualized by users. Losh reports on a video game that panicked the House Intelligence Committee, pedagogic and therapeutic digital products aimed at American soldiers, government Web sites in the weeks and months following 9/11, PowerPoint presentations by government officials and gadflies, e-mail as a channel for whistleblowing, digital satire of surveillance practices, national digital libraries, and computer-based training for health professionals. Losh concludes that the government's "virtualpolitik"--its digital realpolitik aimed at preserving its own power--is focused on regulation, casting as criminal such common online activities as file sharing, video-game play, and social networking. This policy approach, she warns, indefinitely postpones building effective institutions for electronic governance, ignores constituents' need to shape electronic identities to suit their personal politics, and misses an opportunity to learn how citizens can have meaningful interaction with the virtual manifestations of the state.
