22.1 Introduction
The advent of embedded microcontrollers and the possibility to equip them with small, fast, and
low-cost network interfaces has allowed forming smart distributed systems consisting of a set of
networked-embedded devices. The main reasons to build a system in a distributed way are the
possibility to have redundancy and to exploit parallelism. In the context of embedded networks, a
distributed system also supports the following applications:
•
Distributed sensing
with smart transducers. A smart transducer is an integration of
sensor/actuator, processing element, and network interface. Smart transducers perform
a local preprocessing of the analog sensor signal and transmit the measurement digitally
via the network.
