The connected dominating set has been a classic subject studied in graph theory since 1975. Since the 1990s, it has been found to have important applications in communication networks, especially in wireless networks, as a virtual backbone. Motivated from those applications, many papers have been published in the literature during last 15 years. Now, the connected dominating set has become a hot research topic in computer science. In this book, we are going to collect recent developments on the connected dominating set, which presents the state of the art in the study of connected dominating...

This book examines almost two decades of research using the structural or network approach to political behavior. Network analysis begins with the assumption that the most important elements of political power are the relationships of influence and domination among social actors. Influence is the exchange of information about preferences and intentions; domination is the exchange of material sanctions to reward or punish compliance with commands.

Over the past two decades, network technologies have been remarkably renovated and computer networks, particularly the Internet, have permeated into every facet of our daily lives. These changes also brought about new challenges, particularly in the area of security. Network security is essential to protect data integrity, con?d- tiality, access control, authentication, user privacy, and so on. All of these aspects are critical to provide fundamental network functionalities. This book covers a comprehensive array of topics in network security including secure metering, group key management,...
