The recent development of communication and sensor technology results in the
growth of a new attractive and challenging area . wireless sensor networks.
A wireless sensor network which consists of a large number of sensor nodes is
deployed in environmental fields to serve various applications. Facilitated
with the ability of wireless communication and intelligent computation, these
nodes become smart sensors which do not only perceive ambient physical
parameters but also be able to process information, cooperate with each other
and self-organize into the network. These new features assist the sensor nodes
as well as the network to operate more efficiently in terms of both data
acquisition and energy consumption. Special purposes of the applications
require design and operation of WSNs different from conventional networks such
as the internet. The network design must take into account of the objectives
of specific applications. The nature of deployed environment must be considered.
The limited of sensor nodes. resources such as memory, computational ability,
communication bandwidth and energy source are the challenges in network design.
A smart wireless sensor network must be able to deal with these constraints as
well as to guarantee the connectivity, coverage, reliability and security of
network.s operation for a maximized lifetime. This book discusses various
aspects of designing such smart wireless sensor networks. Main topics includes:
design methodologies, network protocols and algorithms, quality of service
management, coverage optimization, time synchronization and security techniques
for sensor networks.
