The topic of "Energy Efficiency in Communications and Networks" attracts growing attention due to economical and environmental reasons. The amount of power consumed by information and communication technologies (ICT) is rapidly increasing, as well as the energy bill of service providers. According to a number of studies, ICT alone is responsible for a percentage which varies from 2% to 10% of the world power consumption. Thus, driving rising cost and sustainability concerns about the energy footprint of the IT infrastructure. Energy-efficiency is an aspect that until recently was only considered for battery driven devices. Today we see energy-efficiency becoming a pervasive issue that will need to be considered in all technology areas from device technology to systems management. This book is seeking to provide a compilation of novel research contributions on hardware design, architectures, protocols and algorithms that will improve the energy efficiency of communication devices and networks and lead to a more energy proportional technology infrastructure.

With the increasing popularization of personal hand-held mobile devices, more people use them to establish network connectivity and to query and share data among themselves in the absence of network infrastructure, creating mobile social networks (MSNet). Since users are only intermittently connected to MSNets, user mobility should be exploited to bridge network partitions and forward data. Currently, data route/forward approaches for such intermittently connected networks are commonly "store-carry-and-forward" schemes, which exploit the physical user movements to carry data around the network and overcome path disconnection. And since the source and destination may be far away from each other, the delay for the destination to receive the data from the source may be long. MSNets can be viewed as one type of socially-aware delay tolerant networks (DTNs). Observed from social networks, the contact frequencies are probably different between two friends and two strangers, and this difference should be taken into consideration when designing data dissemination and query schemes in MSNets. In this book, the fundamental concepts of MSNets are introduced including the background, key features and potential applications of MSNets, while also presenting research topics, such as, MSNets as realistic social contact traces and user mobility models. Because the ultimate goal is to establish networks that allow mobile users to quickly and efficiently access interesting information, particular attention is paid to data dissemination and query schemes in subsequent sections. Combined with geography information, the concepts of community and centrality are employed from a social network perspective to propose several data dissemination and query schemes, and further use real social contact traces to evaluate their performance, demonstrating that such schemes achieve better performance when exploiting more social relationships between users.

Recent advances in mobile and wireless communication and personal computer technology have created a new paradigm for information processing. Today, mobile and wireless communications exit in many forms, providing different types of services. Existing forms of mobile and wireless communications continue to experience rapid growth and new applications and approaches are being spawned at an increasing rate. Recently, the mobile and wireless Internet has become one of the most important issues in the telecommunications arena. The development of the mobile and wireless Internet is the evolution of several different technologies coming together to make the Internet more accessible. Technologies such as the Internet, wireless networks, and mobile computing have merged to form the mobile and wireless Internet. The mobile and wireless Internet extends traditional Internet and World Wide Web services to wireless devices such as cellular phones, Personal Digital Assistants (PDAs) and notebooks. Mobile and wireless Internet c:an give users access to personalized information anytime and anywhere they need it, and thus empower them to make decisions more quickly, and bring them closer to friends, family, and work colleagues. Wireless data communication methods have been around for sometime.
