Energy Consumption in Wireless Sensor Networks. Edition No. 1
VDM Publishing House, Aug 2008, Pages: 76
Wireless Sensor Networks (WSNs) have been intensely
studied because of their potential applications and
technological challenges. However, most analysis of
WSN performance has used only computer simulations,
with greatly simplified assumptions about the
performance of the underlying circuits. WSN network
lifetime depends upon communication protocols. The
Gossip-Based Sleep Protocol (GSP), implements routing
and MAC functions in an energy conserving manner.
However, measuring network lifetime with even a
protocol as simple as GSP is problematic. Multiple
approaches are described for measuring energy
consumption in terms of transmit and receive phases,
minimum voltage supply required for operation and
transmit power. Also multiple methods are described
for measuring the lifetime of a sensor node and
describing end-of-lifetime behavior. The final result
is a model of energy consumption describing the
performance of GSP on the Mica2 platform, which is
then compared with other models. Academic
researchers, professors, students and industrial
researchers in the field of WSNs or concerned about
energy consumption by general wireless communications
devices will be interested in this book.
