Mobile Multimedia is defined as a set of protocols and standards for multimedia information exchange over wireless networks. Therefore the book is organised into four parts. The introduction part, which consists of two chapters introduces the readers to the basic ideas behind mobility management and provides the business and technical drivers, which initiated the mobile multimedia revolution. Part two, which consists of six chapters, explains the enabling technologies for mobile multimedia with respect to data communication protocols and standards. Part three contains two chapters and is dedicated for how information can be retrieved over wireless networks whether it is voice, text, or multimedia information. Part four with its four chapters will clarify in a simple a self-implemented way how scarce resources can be managed and how system performance can be evaluated.
This book addresses the increasing demand to guarantee privacy, integrity, and availability of resources in networks and distributed systems. It first reviews security issues and challenges in content distribution networks, describes key agreement protocols based on the Diffie-Hellman key exchange and key management protocols for complex distributed systems like the Internet, and discusses securing design patterns for distributed systems. The next section focuses on security in mobile computing and wireless networks. After a section on grid computing security, the book presents an overview of security solutions for pervasive healthcare systems and surveys wireless sensor network security.

Well over a million people of Sri Lankan origin live outside South Asia. The Encyclopedia of the Sri Lanka Diaspora is the first comprehensive study of the lives, culture, beliefs and attitudes of immigrants and refugees from this island. The volume is a joint publication between the Institute of South Asian Studies, NUS, and Editions Didier Millet. It focuses on the relationship between culture and economy in the Sri Lanka diaspora in the context of globalisation, increased transnational culture flows and new communication technologies. In addition to the geographic mapping of the Sri Lanka diaspora in the various continents, thematic chapters include topics on “long distance nationalism”, citizenship, Sinhala, Tamil and Burgher disapora identities, religion and the spread of Buddhism, as well as the Sri Lankan cultural impact on other nations.
User identification and authentication are absolutely essential to modern security. Mechanics of User Identification and Authentication presents the general philosophy of user authentication and access control. Introducing key concepts, this text outlines the process of controlled access to resources through authentication, authorization, and accounting. It provides specific information on the user authentication process for both UNIX and Windows. Addressing more advanced applications and services, the author presents common security models such as GSSAPI and discusses authentication architecture. Each method is presented with a specific authentication scenario.
