A belt region can be used to describe a border area, which has the
characteristic as a long strip area. Intruders may want to trespass
this region without authorization. To prevent this illegal border
crossing, a mobile sensor network can be deployed in the region.
Mobile sensors can move throughout a region looking for an intruder,
while the number of mobile sensor nodes can be kept at the
minimum. However, there are some design factors that impact the
intruder detection probability of a mobile sensor network. These
factors are environment model, intruder arrivals, intruder mobility,
sensing capability of a sensor node, and sensor selection mechanism.
By understanding the impacts of these factors to the intruder
detection probability, a mobile sensor network can be designed for
better performance. This paper presents a decent method to derive
the intruder detection probability and analyzes the effects of the
design factors to the intruder detection probability. The result will
guide the way to design a mobile sensor network in a belt region
with improved intruder detection probability. |
