General
Introduction :
The
progress made in recent decades in the fields of microelectronics,
micromechanics,
and wireless communication technologies have produced with a reasonable
cost and a
few cubic millimeters in volume components named sensor nodes.
These
small devices equipped with advanced sensing functionalities and a small
processor
operate
independently and communicate with each other via short-range transmissions in
order to
build a global view of a monitored region. Thus, new areas of investigation
have been
opened to
provide remote monitoring and data processing in complex environments through
sensor
nodes which form collectively a Wireless Sensor Network (WSN). The application
scenarios
for WSNs are several, including military supervision, commercial,
environmental,
medical,
manufacturing and home automation, despite this advances, security continues to
be
a main challenge that must be
resolved.
