Such sensor networks
are anticipated to use some form of duty-cycling or other power-saving
schemes. The accuracy and coverage of detection and tracking improves
with more sensor nodes being awake. However, the energy consumption
will be higher if more sensor nodes are awake more often. Thus, there is
a tradeo?® between the accuracy and coverage, and the energy-e?±ciency.
This represents another direction for future work.
29 Chapter 1 Design of Large-scale Sensor Networks
Aravind Iyer et al.
By means of this chapter, we have motivated and provided a taxonomybased
framework to design communication protocols for WSNs. We have provided
a brief survey of the literature, and a sampling of some problems for
future research. The discussion of the various issues considered in this chapter
is by no means exhaustive or complete. There are several other factors and design
considerations to be tackled, before we can design and deploy large-scale,
reliable and e?±cient sensor networks.
