<title>ABSTRACT</title>
<p>We introduce a disaster-zone-monitoring web-based application. While using this application, the user may simulate
different large-scale disaster zones. He may use tools to define a disaster zone and its communication requirements.
The web application uses the <italic>Google Earth</italic> infrastructure
and is publicly available to use online during the conference from every computer connected to the Internet. The
evolving deployment of nodes will be updated each second
to reflect the current state of the entities residing within the
monitored zone.</p>
<p>The user will be able to navigate through the disaster
zone to inspect the dynamically changed environment, and
to learn about node deployment and the current network
connectivity and service availability. He could ask the system to find the number of agents required to be deployed
and present this deployment. The user also will be able to
define the budget limitations. Thus, the system will derive
the number of agents, their deployment, and the resulting
system utility. Given a system utility, the user can decide
whether to adopt the deployment even though it does not
guarantee full coverage, or to increase the budget to improve
system utility.
