Abstract
Wireless sensor networks can be a convenient monitoring system for wide areas,
because they are economically advantageous and they should be more
specialized than remote sensing. Many different systems have been proposed as
wireless sensor networks. Some networks are based on an IP protocol, as a web
of objects. However, other solutions can be adopted when mostly the network is
realized outside of an internet framework or when the internet connection can be
limited at a few nodes. Architectures based on ZigBee protocol are an evident
example. The IEEE 802.15.4 standard communication protocol of Wireless
Personal Area Network (WPAN) defines the best characteristic of low-power,
but limited data rate. It is a good candidate as the standard communication for
many applications and monitoring activities. After the introduction of trends in
the field of low power sensors networks, the design of a particular monitoring
network will be presented: the early-warning of flood river control and
intervention management.
Keywords: WSN, low power, low voltage.
1 Introduction
Disaster management needs a detailed monitoring of the environment, theatre of
calamitous events, together with the actual human and material resources that are
ready for intervention. Monitoring can be realized in different modes. For wide
areas, as a country or province, remote sensing is more convenient. For non large
terrestrial surfaces, distributed sensors are cheaper and more specialized. In the
case of sensors at ground, they must detect both parameters of interest and the
terrestrial coordinates where measurement was carried out. If it mounts a sensor
