The book examines how Fog will change the information technology industry in the next decade. Fog distributes the services of computation, communication, control and storage closer to the edge, access and users. As a computing and networking architecture, Fog enables key applications in wireless 5G, the Internet of Things, and big data.The authors cover the fundamental tradeoffs to major applications of fog. The book chapters are designed to motivate a transition from the current cloud architectures to the Fog (Chapter 1), and the necessary architectural components to support such a transition (Chapters 2-6). The rest of the book (Chapters 7-xxx) are dedicated to reviewing the various 5G and IoT applications that will benefit from Fog networking. This volume is edited by pioneers in Fog and includes contributions by active researchers in the field.

• Covers fog technologies and describes the interaction between fog and cloud
• Presents a view of fog and IoT (encompassing ubiquitous computing) that combines the aspects of both industry and academia
• Discusses the various architectural and design challenges in coordinating the interactions between M2M, D2D and fog technologies
• "Fog for 5G and IoT" serves as an introduction to the evolving Fog architecture, compiling work from different areas that collectively form this paradigm

1.1 INTRODUCTION

The last decade has seen a rapid diversification of computing platforms, devices, and services. For example, desktops used to be the primary computing platform until the turn of the century. Since then, laptops and more recently handheld devices such as laptops and tablets have been widely adopted. Wearable devices and the Internet of things (IoT) are the latest trends in this space. This has also led to widespread adoption of the “cloud” as a ubiquitous platform for supporting applications and services across these different devices.

Simultaneously, cloud computing platforms, such as Amazon EC2 and Google App Engine, have become a popular approach to provide ubiquitous access to services across different user devices. Third‐party developers have come to rely on cloud computing platforms to provide high quality services to their end users, since they are reliable, always on, and robust. Netflix and Dropbox are examples of popular cloud‐based services. Cloud services require developers to host services, applications, and data on off‐site data centers. But, due to application‐specific reasons, a growing number of high quality services restrict computational tasks to be colocated with the end user. For example, latency‐sensitive applications require the backend service to be located to a user’s current location. Over the years, a number of research threads have proposed that a better end‐user experience is possible if the computation is performed close to the end user. This is typically referred to as “edge computing” and comes in various flavors including: cyber foraging [1], cloudlets [2], and more recently fog computing [3].

This chapter presents a unique edge computing framework, called ParaDrop, which allows developers to leverage one of the last bastions of persistent computing resources in the end customer premises: the gateway (e.g., the Wi‐Fi access point (AP) or home set‐top box). Using this platform, which has been fully implemented on commodity gateways, developers can design virtually isolated compute containers to provide a persistent computational presence in the proximity of the end user. The compute containers retain user state and also move with the users as the latter changes their points of attachment. We demonstrate the capabilities of this platform by demonstrating useful third‐party applications, which utilize the ParaDrop framework. The ParaDrop framework also allows for multitenancy through virtualization, dynamic installation through the developer API, and tight resource control through a managed policy design.

1.1.1 Enabling Multitenant Wireless Gateways and Applications through ParaDrop

A decade or two ago, the desktop computer was the only reliable computing platform within the home where third‐party applications could reliably and persistently run. However diverse mobile devices, such as smartphones and tablets, have deprecated the desktop computer since, and today persistent third‐party applications are often run in remote cloud‐based servers. While cloud‐based third‐party services have many advantages, the rise of edge computing concepts stems from the observation that many services c...
