Future Work
nUltimately, our goal is to develop reliable
and secure multicast
solutions (pending finding unsuspecting students to do the work).
nBCAST used as starting point with a
NACK-based retransmission
scheme to further increase PDR
nLessons learned to date: congestion control is more important than packet retransmission scheme (when network is congested, NACKs make bad situation worse, independent of network capacity)
nImplemented BCAST on Linux laptops, with some preliminary work comparing simulation results and
testbed measurements (using
MNE, driven by NS2 traces)
ØUnfortunately, testbed measurements correspond neither quantitatively nor qualitatively with NS2 results
