ABSTRACT
Collaboration planning (CP) and the Inmarsat on the
move satellite system were key enabling technologies for
Corps and Division level commanders during Operation
Iraqi Freedom (OIF). CP consists of planning tools such
as whiteboarding, chat, voice conferencing, and file sharing
with numerous collaborative tools commercially available
today. The DoD standard for collaboration is the
Defense Collaboration Tool Suite (DCTS). While the Inmarsat
and DCTS capabilities provided significant improvements
in capability for the warfighter, the scalability
of these technologies is limited. The commercial CP tools
within DCTS such as Microsoft's Net Meeting are optimized
for operation on high speed wired networks, and
consequently do not operate well over low bandwidth tactical
networks. Additionally the Inmarsat architecture employed
is very cost prohibitive when scaled beyond a handful
of Army commanders. This paper provides an overview
of a prototype Tactical Collaboration Tool (TCT) that was
developed to operate over low bandwidth wireless networks,
along with recommendations for improving the Inmarsat
satellite architecture. The paper includes an
analysis of the performance of the TCT over a simulated
Inmarsat network, and contrasts it against commercial CP
tools.
