status (active, dormant)
Max Num of TripWire Base a node can remember, currently set be 5
Find min hop, if it choose the first one
and that all nodes attach to the nearest base nodes
through the shortest path.
voltages are always selected as sentries.
The average minimum distances
between sentry-pairs is 9.57 meters
with 1.88 meters standard deviation.
communication delay < detection report < classification delay < velocity estimations delay
SDC↓, detection delay↓
1)To reduce the detection delay,
choose a sentry toggle period as small as possible.
2)To increase the network lifetime, select a small sentry duty cycle.
STP↓, detection prob↑
a low tripwire duty cycle(TDC) increases the network lifetime, but increases the detection delay and decreases
the detection probability
TDC↓, detection delay↑
it takes more time to
detect slow targets than faster ones;
a high target speed
decreases the detection delay
