According to a report of United Nations, more than two-thirds of the world’s population will live in cities by 2050. In response to the enormous challenges of urbanization such as traffic congestion and environmental pollution, many cities embrace the Smart City concept to optimize city operations. This course aims to find out "What made Smart City smart" by exploring the key building blocks of Smart City, which are sensors, networks, and data analysis technologies.
This book provides a smart and accessible introduction to the handful of big ideas that drive the computer networks we use every day. It unifies these ideas through six fundamental principles of networking. These principles explain the difficulties in sharing network resources efficiently, how crowds can be wise or not so wise depending on the nature of their connections, why there are many layers in a network, and more. Along the way, the authors also talk with and share the special insights of renowned experts such as Google’s Eric Schmidt, former Verizon Wireless CEO Dennis Strigl, and “fathers of the Internet” Vint Cerf and Bob Kahn.
This book focuses on the fundamental issues of networking as well as approaches towards addressing these issues. Beginning with application-level protocols and then working down the protocol stack, an early emphasis is placed on application-layer paradigms and application programming interfaces to allow readers to touch on protocols and networking concepts in the context of applications they will use in the industry. This third edition contains a new chapter on wireless and mobile networking, including in-depth coverage of Wi-Fi, Mobile IP, and GSM, and expanded and revised sections on peer-to-peer networking, BGP, wireless security, DNS, and more.
