Africa is a source of amazing bio-diversity and home to some of the planet's most spectacular landscapes. The sights of this awe-inspiring continent are captured with consummate skill and sensitivity by master lensman Michael Poliza. With extensive experience photographing the animals and terrain of Africa, Poliza's viewpoint is shaped by his concern for the fragile eco-systems he chronicles. These images embody the soul of Africa's flora and fauna with a true artist's eye for color and composition. This book will be enjoyed for years to come. Poliza started as a child actor on German TV, then founded several highly successful IT ventures in the US and Germany.

An ideal gift, both for the lover of fine art photography and the keen naturalist ? A timeless collection highlighting the beauty of Africa's natural riches

Unique book addressing cooperative algorithms at the MAC layer Cooperative Communications: MAC Protocols focuses on issues pertaining to the MAC layer of wireless cooperative communication networks, offering a rigorous taxonomy of this dispersed field, along with a range of application scenarios for cooperative and distributed schemes to show how these techniques can be employed. The authors provide rigorous analytical tools for reservation and contention based MACs, as well as hybrids. This is complemented by an application of developed techniques to specific wireless standards. There is currently no book on the market which coherently discusses cooperative algorithms at the MAC layer. Introduces background, concepts, applications, milestones and thorough taxonomy of the field, along with a range of application scenarios Identifies the potential in this emerging technology applied to e.g. LTE/WiMAX, WSN Explores reservation-based, contention-based and hybrid cooperative MAC protocols, and applies rigorous mathematical tools to these Demonstrates cross-layer design to boost performance Addresses advanced MAC topics, such as opportunistic and network coded MACs Highlights future research challenges within the cooperative communications Includes an accompanying website ( http://books.cttc.es )
