“The suspense was killing me. I just had to read it straight through!” Although these responses to our book would be gratifying, it’s doubtful that any book on digital security will ever garner this type of reaction. Digital security is the computer equivalent of disaster insurance. Few people care very much about it or give it much thought, and everyone hates paying for it … until a ca…
One of the many experiences I value from my time participating in the 802.11 working group is the ability to compare the “outside” view of a technology with the “inside” view of people in the engine room sweating to make it work. From the outside, wireless LANs have seen a steady progression in speeds from a megabit in the late 1990s to a gigabit with the first release of 802.11ac in 20…
“Now, of course, a free and open internet is vital. But in no other market and with no other industry do we have such an extraordinarily light touch when it comes to protecting our children. Children can’t go into the shops or the cinema and buy things meant for adults or have adult experiences; we rightly regulate to protect them. But when it comes to the internet, in the balance between f…
In this introductory chapter, the subject of the book is explained in more detail by focusing on two central issues of the control of networks: open-loop control of interconnected systems and synchronization. While the first topic emphasizes the computational aspects involved in controlling interconnected systems, the second theme of synchronization discusses the impact of couplings on the shap…
It is a sad fact that much of the world is dominated by short-term thinking. And an in-depth look at the numerous problems that humanity now faces often reveals that the downside of allowing individuals or groups to do whatever they want (without considering future consequences) usually results in all of us paying dearly for it. Equally as true is that an increasing number of people and their…
Recently, the number of social networking sites is rapidly increasing, and the number of users joining these sites is dramatically increasing as well. This paper aims at comprehensively comparing three social networking sites, and provides an in-depth analysis. We compare three of the most popular social networking sites, i.e., Facebook, Twitter and MySpace. Specifically, we evaluate those soci…
In 2014, UN Member States proposed a set of Sustainable Development Goals (SDGs), which will succeed the Millennium Development Goals (MDGs) as reference goals for the international development community for the period 2015-2030. The proposed goals and targets can be seen as a network, in which links among goals exist through targets that refer to multiple goals. Using network analysis techniqu…
Several years ago I wrote a book about the proper role of the judiciary— particularly the federal judiciary, and especially the Supreme Court of the United States—in adjudicating constitutional issues.1 In that book I assumed that there can be right answers—and wrong ones, too—to questions of morality. (I was concerned principally with questions of political morality. I argued thatjudge…
Mobile Online Social Networks (mOSNs) have recently grown in popularity. With the ubiquitous use of mo- bile devices and a rapid shift of technology and access to OSNs, it is important to examine the impact of mobile OSNs from a privacy standpoint. We present a taxonomy of ways to study privacy leakage and report on the cur- rent status of known leakages. We find that all mOSNs in our study ex…
If you were in a state of cryogenic suspension for the past two decades and suddenly awoke, you would find yourself inundated with information coming from the use of cellular phones, personal computers connected to the Internet, tablets, digital music players, e-book readers, high-definition televisions, digital cameras, and a variety of other digital gadgets that have entered common households…
Welcome to Wireless Home Networking For Dummies. Wireless network- ing for personal computers is not really a new idea; it’s been around for at least five years. The emergence of an industry standard, however, has caused the use of wireless networking technology to explode. One of the most appealing things about the current crop of wireless network- ing equipment is the ease with which you c…
Subsequent to the mathematical theory of electromagnetic waves formulated by James Clerk Maxwell in 1873 [3] and the demonstration of the existence of these waves by Heinrich Hertz in 1887, Guglielmo Marconi made history by using radio waves for transat- lantic wireless communications in 1901. In 1906, amplitude modulation (AM) radio was invented by Reginald Fessenden for music broadcasting. In…
This forecast is part of the Cisco Visual Networking Index™ (Cisco VNI™), an ongoing initiative to track and forecast the impact of visual networking applications. This document presents the details of the Cisco VNI global IP traffic forecast and the methodology behind it. For a more analytical look at the implications of the data presented in this paper, refer to the companion document,
NP-hard optimization problems exhibit a rich set of possibilities, all the way from allowing approximability to any required degree, to essentially not allowing approximability at all. Despite this diversity, underlying the process of design of approximation algorithms are some common principles. We will explore these in the current chapter. An optimization problem is polynomial time solvable …
