无线传感网络，Wireless sensor networks promise an unprecedented fine-grained interface
between the virtual and physical worlds. They are one of the most rapidly devel
oping new information technologies, with applications in a wide range of fields
including industrial process control, security and surveillance, environmental
sensing, and structural health monitoring. This book is motivated by the urgent
need to provide a comprehensive and organized survey of the field. It shows how
the core challenges of energy efficiency, robustness, a
nd autonomy are addressed
in these systems by networking techniques across multiple layers. The topics
covered include network deployment, localization, time synchronization, wire
less radio characteristics, medium-access, topology control, routing, data-centric
techniques, and transport protocols.
Ideal for researchers and designers seeking to create new algorithms and protocols
and engineers implementing integrated solutions, it also contains many exercises
and can be used by graduate students taking courses in networks.
