The following are important issues pertaining to WSNs (see also Table 1.1):
sensor type; sensor placement; sensor power consumption, operating environment,
computational/sensing capabilities and signal processing, connectivity, and telemetry or control of remote devices. It is critical to note in this context that node location and fine-grained time (stamping) are essential for proper operation of a sensor
network; this is almost the opposite of the prevalent Internet architecture, where
server location is immaterial to a large degree and where latency is often not a
key consideration or explicit design objective.
