书籍 Ambient Networks
One traditional view of how wireless networks evolve is of a continuous, inevitable progres-
sion to higher link speeds, combined with greater mobility over wider areas. This standpoint
certainly captures the development from first and second generation cellular systems focused
on voice support, and ...
书籍 Cooperative+Communications
Cooperation is not a natural characteristic attributed to humans. The typical human horizon is focused
on short-term gains, which might be due to our instinct-driven subconscious occupying a grander
importance than we dare to admit [1]. Cooperating with other individuals or entities, however, usuall ...

书籍 Stochastic Geometry and Wireless Networks Volume I
Part I provides a compact survey on classical stochastic geometry models. The basic models defined
in this part will be used and extended throughout the whole monograph, and in particular to SINR based
models. Note however that these classical stochastic models can be used in a variety of contexts w ...
书籍 Wireless Communications & Networking
During the past three decades, the world has seen signifi cant changes in the telecom-
munications industry. There has been rapid growth in wireless communications, as
seen by large expansion in mobile systems. Wireless communications have moved
from fi rst-generation (1G) systems primarily focused ...
书籍 RESTful+Rails+Development+Building
This book is focused on designing and developing Representational State Transfer (REST)
platforms in Rails. REST is the architectural style of the Web, consisting of a set of
constraints that, applied to components, connectors, and data elements, constitute the
wider distributed hypermedia system th ...
