Revolutionary networking concepts and unprecedented mix of technical
challenges have made Wireless Sensor Networks (WSN) one of the
major research trends of the 21th century.
However, only very recently did such systems start to appear as
products on the market. In this new context, this paper aims at
providing a general status on WSNs, with a special focus on the
device aspects, independent of application peculiarities. We first
investigate why, despite years of research and development and
technical maturity, WSN products and solutions are yet neither
fully adopted nor widely deployed. We then review the state-of-the
art technologies that build most of today’s available products
and finally briefly discuss some advanced techniques for future
generations of WSN systems.
