att_abstract={{Geographic addressing (GA) is a way of addressing messages in a
network. In GA, the destination of a message is specified as a geographic
region. The network delivers the message to all devices in that
region. A representative application is to distribute Common Operating
Picture updates to interested devices. This paper extends previous
research on GA to handle challenging problems arising in
real-world implementations: large scale, network heterogeneity and
multiple security domains. After first laying out the problem and
challenges, we describe SGAF, a scalable geographic addressing
framework for building and combining scalable GA systems.  We
illustrate and evaluate SGAF using a case study of one implementation
of the framework, the AT&T Labs Geocast System.}},
