Supporting Emergency-Response by Retasking Network Infrastructures

Presenter: Micheal LeMay
Greg: How the proposed system routes the messages?
M: GPS information can be used together with
Q: It looks like there is a
significant additional engineering effort needed to add proposed
functions. What are the guarantees that the system will work? It would
be difficult to characterize what are the likely benefits, in
particular, would you be able to quantify how well your system would
work in case of a disaster scenario?
A: It is an important
quantification question. One can determine probabilities for different
events, especially of larger events happening and calculate possible
benefits. For smaller events, such as fires, the calculation is more
Q: If we re-design these
low-bandwidth wireless networks to carry data, wouldn’t they collapse?
What policies would prevent that?
A: There are some general policies
applicable in each scenario. For example, it is possible to apply
specific time slots for rescuers.
Comment: The Catrina was brought as
an example, however it wasn’t that bad, was it? Land-line phones
worked, pay-phones worked, communication installations in downtown
worked. Was it that bad?
Q: Wouldn’t it be more cost
effective to deploy specialized nodes after the disaster strikes
instead of re-engineering conventional networks? The cost benefits
might be huge.
A: Maybe, good idea! The questions
is whether the coverage could be as complete as it is in proposed case.
There is also advantage edge, because it is difficult to match the
coverage of something as ubiquitous as millions of ZigBee devices.
