Networks - Emerging Topics in Computer Science is suitable for advanced undergraduate students and postgraduate students who are searching for research topics related to networks or requiring brainstormings against network applications. It discusses various aspects related to networks, from large-scale/geo-scale networks to micro-scale networks such as network-on-chip (NoC). The contents of this book is designed in the way such that it tries to make a good balance among different major topics in networks (e.g., network models, network theories, network infrastructures and network applications), so that it suits people from different backgrounds, especially those who are strong in one area but are not familiar with other areas. This book is an invaluable companion for students from their first encounter with the subject to more advanced studies, while the high quality artworks are designed to present the key concepts with simplicity, clarity and consistency.
