Intra-system EMC problems are becoming increasingly common in mobile devices, ranging from notebook PCs to cell phones, with RF/wireless capbilities. These issues range from minor annoyances to serious glitches which impede the functioning of the device. This book gives a thourough review of electromagnetic theory (including Maxwell's equations), discusses possible sources and causes of intra-system interference, shows to use models and analysis to discover potential sources of intra-system EMC in a design, how to use appropriate tests and measurements to detect intra-system EMC problems, and finally extensively discusses measures to mitigate or totally eliminate intra-system EMC problems. With more and more mobile devices incorporating wirless capability (often with multiple wireless systems, such as Bluetooth and WiFi), this book should be part of the reference shelf of every RF/wireless engineer and mobile device designer.

How do you balance battery life with performance and cost?
This book shows you how!
Now that "mobile" has become the standard, the consumer not only expects mobility but demands power longevity in wireless devices. As more and more features, computing power, and memory are packed into mobile devices such as iPods, cell phones, and cameras, there is a large and growing gap between what devices can do and the amount of energy engineers can deliver. In fact, the main limiting factor in many portable designs is not hardware or software, but instead how much power can be delivered to the device. This book describes various design approaches to reduce the amount of power a circuit consumes and techniques to effectively manage the available power.
Power Management Advice On:
-Low Power Packaging Techniques
-Power and Clock Gating
-Energy Efficient Compilers
-Various Display Technologies
-Linear vs. Switched Regulators
-Software Techniques and Intelligent Algorithms
* Addresses power versus performance that each newly developed mobile device faces
* Robust case studies drawn from the author's 30 plus years of extensive real world experience are included

Over the past decade, the world has witnessed an explosion in the development and deployment of new wireless network technologies. From cellular mobile telephony to the ubiquitous "WiFi" networks in coffee-shops and airports, to the emerging WiMAX wireless broadband access networks, the menu of wireless access systems has become so comprehensive that wireline access to user devices may soon become a relic of the past. Wireless Networking serves as a one-stop view of cellular, WiFi, and WiMAX networks, as well as the emerging wireless ad hoc and sensor networks. Rather than provide descriptive accounts of these technologies and standards, the book emphasizes conceptual perspectives on the modeling, analysis, design and optimization of such networks. Furthermore, the authors present wireless networking within the unifying framework of resource allocation, using simple abstractions of the underlying physical wireless communication. In short, Wireless Networking is an in-depth, exhaustive, and invaluable asset to anyone working in this rapidly evolving field.

Securing communications is a challenging task. A ?rst attempt at security involves learning basic cryptography, and applying encryption algorithms to make messages unintelligible to adversaries. However, rarely is the task of securing a message - changesosimple.Whenonestepsbackandcontemplateshowtosecuretheexchange of communications, one realizes that the challenge is fundamentally one of bui- ing a complete solution. For example, one must ensure that all entities involved have proper and authenticated cryptographic material, or one must ensure that one veri?ably knows to whom one is communicating, or one must understand how the communication process takes place so as to make certain there are no vulnerabilities introduced by the communication process itself. Thislastissue, namelythatsecuritymethodsareoftenbuiltwithoutconsideration to how communication takes place, represents a fundamental gap where much of modern security research has fallen short.The security literature is ?lled with a mass of articles on cryptographic primitives and, although there are still many theoretical hurdlestobeovercomebythecryptographiccommunity,mostoftheseshortcomings areacademicandtherearenownumeroustextbooksoncryptographythatcanprovide thebasicintroductionneededtoemploycryptographicprimitives. Ontheothersideof thecoin,thesecurityliteratureisalso?lledwithamassofarticlesdevotedtobuilding secure protocols and, similarly, there are now numerous textbooks on computer securitythatprovidetheinstructionneededtodesignsecureprotocols.Unfortunately, the issue of how communication takes place or, more speci?cally, whether there are any speci?c issues that might arise or be circumvented because message exchanges aretakingplaceononemediumversusanother(e.g., wirelesscommunicationversus wired communication), is generally neglected.

This book provides insight into the challenges in providing data authentication over wireless communication channels. The authors posit that established standard authentication mechanisms - for wired devices - are not sufficient to authenticate data, such as voice, images, and video over wireless channels. The authors propose new mechanisms based on the so-called soft authentication algorithms, which tolerate some legitimate modifications in the data that they protect. The authors explain that the goal of these algorithms is that they are tolerant to changes in the content but are still able to identify the forgeries. The authors go on to describe how an additional advantage of the soft authentication algorithms is the ability to identify the locations of the modifications and correct them if possible. The authors show how to achieve this by protecting the data features with the help of error correcting codes. The correction methods are typically based on watermarking, as the authors discuss in the book. Provides a discussion of data (particularly image) authentication methods in the presence of noise experienced in wireless communication; Presents a new class of soft authentication methods, instead of the standard hard authentication methods, used to tolerate minor changes in image data; Features authentication methods based on the usage of authentication tags as well as digital watermarks.

In the last few years, a stimulating idea is fast emergingin the wireless scenario: the pervasive presence around us of a variety of "things" or "objects," such as RFID, sensors, actuators, mobile phones, which, through unique addressing schemes, are able to interact with each other and cooperate with their neighboring "smart" c- ponents to reach common goals. This novel paradigm, named "The Internet of Things" (IoT) continues on the path set by the concept of smart environments and paves the way to the depl- ment of numerous applications with a signi cant impact on many elds of future every-day life. In this context, logistics, Intelligent Transportation Systems (ITS), business/process management, assisted living, and e-health are only a few examples of possible application elds in which this novel paradigm will play a leading role in the next future.
