This poster describes a simulation testbed being developed
under the ARPA (Advanced Research Projects Agency) funded
TRAVLER project. The goal of the TRAVLER project is to contribute
critical technologies to develop a transparent virtual
networking environment for mobile computing.
TRAVLER system architecture consists of
several layers: Application layer (e.g. WWW) being the top-most, and
communication substrate (radio/wired/dialup) being the bottom-most.
When complete, the TRAVLER simulation
testbed would include
(a)
standard APIs for each layer to support plug 'n play prototyping and
performance evaluation of simulation or operational components
belonging to any layer (e.g. radios, networks, file systems, OS
etc.),
(b) a library of
simulation models, at different levels of detail, for components in
each layer,
(c) easy-to-use textual and visual simulation languages to
allow users to write new simulation models,
(d) an ability to execute the simulation on parallel computers for
greater speed, and
(e) an ability to use operational components in simulation systems (
for more accurate/faster hybrid simulation), and simulation
components in operational systems (for on-line simulation to improve
the peformance of operational system components).
