This book was released on 2004-09 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rapid employment of wireless networks commercially, the military is seeking viable solutions for providing high-speed wireless network throughout the battle space. The IEEE 802.11a wireless LAN presents an attractive solution providing up to 54 Mbps data-link bandwidth. Moreover, it operates in the less congested 5-GHz U-NII band and possesses more operating channels. This research implemented two prototype systems using low-cost commercially available hardware. The Cisco Aironet 1400 wireless bridge and the Proxim Tsunami MP.11a wireless system were chosen for their superior specifications and for their reputation of being market leaders in IEEE 802.11 wireless products. The performances of the prototype systems were evaluated in three operational environments (land, water and vegetation). The data collected were then compared to the theoretical performance.

This book was released on 2009-12-18 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The First International ICST Conference on Communications Infrastructure, Systems and Applications in Europe (EuropeComm 2009) was held August 11–13, 2009, in London. EuropeComm 2009 brought together decision makers from the EU comm- sion, top researchers and industry executives to discuss the directions of communi- tions research and development in Europe. The event also attracted academia and industry representatives, as well as government officials to discuss the current dev- opments and future trends in technology, applications and services in the communi- tions field. Organizing this conference was motivated by the fact that the development and - ployment of future services will require a common global-scale infrastructure, and therefore it is important that designers and stakeholders from all the systems stacks come together to discuss these developments. Rapidly decreasing costs of compu- tional power, storage capacity, and communication bandwidth have led to the dev- opment of a multitude of applications carrying an increasingly huge amount of traffic on the global networking infrastructure. What we have seen is an evolution: an inf- structure looking for networked applications has evolved into an infrastructure str- gling to meet the social, technological and business challenges posed by the plethora of bandwidth-hungry emerging applications.

This book was released on 2010 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cognitive radio – a paradigm for wireless communication in which either a network or a wireless node changes its transmission or reception parameters to communicate more efficiently and avoid interference -- is one of the most exciting emerging fields in communications technology. Taking an integrated development approach, this cutting-edge book provides you with clear methods for performing quantitative analysis of cognitive radio techniques in a variety of environments. This detailed reference presents a quantitative structure that helps you determine the capability of cognitive radio to address a number of constraints of current radio design. Critical to understanding the operation of cognitive radio, the book develops an analytic model for a range of spectrum environments. Moreover, this unique resource offers you unique insight into the application of dynamic spectrum access (DSA) to improve the performance of all classes of wireless devices. DVD Included! Contains sample cognitive radio environments and closed form approximations of these environments in MATLAB file format. This data enables you to reproduce the analysis provided in the book, perform the exercises in each chapter, and extend the work through independent investigation and research.
Download or read book Ad Hoc Networks written by Jun Zhi-zhong and published by Springer Science & Business Media. This book was released on 2010-12-15 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ad hoc networks, which include a variety of autonomous networks for specific purposes, promise a broad range of civilian, commercial, and military applications. These networks were originally envisioned as collections of autonomous mobile or stationary nodes that dynamically auto-configure themselves into a wireless network without relying on any existing network infrastructure or centralized administration. With the significant advances in the last decade, the concept of ad hoc networks now covers an even broader scope, referring to the many types of autonomous wireless networks designed and deployed for a specific task or function, such as wireless sensor networks, vehicular networks, home networks, and so on. In contrast to the traditional wireless networking paradigm, such networks are all characterized by sporadic connections, highly error-prone communications, distributed autonomous operation, and fragile multi-hop relay paths. The new wireless networking paradigm necessitates reexamination of many established concepts and protocols, and calls for developing a new understanding of fundamental problems such as interference, mobility, connectivity, capacity, and security, among others. While it is essential to advance theoretical research on fundamental and practical research on efficient policies, algorithms and protocols, it is also critical to develop useful applications, experimental prototypes, and real-world deployments to achieve an immediate impact on society for the success of this wireless networking paradigm.
