This article discusses aspects of communication architecture for early
warning systems (EWS) in general and gives details of the specific
communication architecture of an early warning system against tsunamis.
While its sensors are the "eyes and ears" of a warning system and enable
the system to sense physical effects, its communication links and terminals
are its "nerves and mouth" which transport measurements and estimates
within the system and eventually warnings towards the affected population.
Designing the communication architecture of an EWS against tsunamis is
particularly challenging. Its sensors are typically very heterogeneous and
spread several thousand kilometers apart. They are often located in remote
areas and belong to different organizations. Similarly, the geographic
spread of the potentially affected population is wide. Moreover, a failure
to deliver a warning has fatal consequences. Yet, the communication
infrastructure is likely to be affected by the disaster itself. Based on an
analysis of the criticality, vulnerability and availability of communication
means, we describe the design and implementation of a communication system
that employs both terrestrial and satellite communication links. We believe
that many of the issues we encountered during our work in the GITEWS project
(German Indonesian Tsunami Early Warning System, Rudloff et al., 2009) on the
design and implementation communication architecture are also relevant for
other types of warning systems. With this article, we intend to share our
insights and lessons learned. |
