This book constitutes the refereed proceedings of the 10th International Conference on Ad-hoc, Mobile, and Wireless Networks, ADHOC-NOW 2011 held in Paderborn, Germany, July 18-20, 2011.

The 23 revised full papers presented together with 4 invited papers were carefully reviewed and selected from 53 submissions. The papers are organized in topical sections on routing and activity scheduling, topology control, medium access control, security, mobility management and handling, applications and evaluation, and analytical considerations.

With success of ICEEE 2010 in Wuhan, China, and December 4 to 5, 2010, the second International Conference of Electrical and Electronics Engineering (ICEEE 2011) will be held in Macau, China, and December 1 to 2, 2011. ICEEE is an annual conference to call together researchers, engineers, academicians as well as industrial professionals from all over the world to present their research results and development activities in Electrical and Electronics Engineering along with Computer Science and Technology, Communication Technology, Artificial Intelligence, Information Technology, etc.

Continuous-Time Signals is an extended description of continuous-time signals related to the course of Signals and Systems. As a time-varying process of any physical state of any object, which serves for representation, detection, and transmission of messages, a modern electrical signal possesses, in applications, many specific properties. To make possible for readers to deal with signals free, the book systematically covers major principle foundations of the signals theory. The representation of signals in the frequency domain (by Fourier transform) is considered with...

Well over a billion people are currently using cellular telephones, and this number is expected to grow to over two billion in the next few years. It is remarkable that a device that was considered a high-technology "toy" just a few years ago is now an indispensable feature of modern life. One of the key reasons for this remarkable transformation is the integration of all the radio functions of a cellular telephone onto a single inexpensive piece of silicon. This achievement is a result of innovations in design and process technology that allowed formerly discrete and separate devices to...

Recently, wireless LAN standards have emerged in the market. Those standards operate in various frequency ranges. To reduce component count, it is of importance to design a multi-mode frequency synthesizer that serves all wireless LAN standards including 802.11a, 802.11b and 802.11g standards. With different specifications for those standards, designing integer-based phase-locked loop frequency synthesizers can not be achieved. Fractional-N frequency synthesizers offer the solution required for a common multi-mode local oscillator. Those fractional-N synthesizers are based on delta-sigma...

Much energy has been spent on the subject of spectrum scarcity that would threaten to stunt the growth of wireless technologies and services. This concern comes on the heels of the great successes of both cellular communications and consumer oriented communications like Wi-Fi and Bluetooth that have changed the way people use computers and communications and that have led to the creation of large new markets for products and services.

The response of many spectrum regulators throughout the world in addressing these concerns has been to consider releasing more spectrum for unlicensed...

Electronic Devices for Analog Signal Processing is intended for engineers and post graduates and considers electronic devices applied to process analog signals in instrument making, automation, measurements, and other branches of technology. They perform various transformations of electrical signals: scaling, integration, logarithming, etc. The need in their deeper study is caused, on the one hand, by the extension of the forms of the input signal and increasing accuracy and performance of such devices, and on the other hand, new devices constantly emerge and are already widely used...
