•Not the same quantitative results (was expected)
•However, also not the same qualitative results!
•Reliable BCAST does not increase the PDR for low traffic loads (independent of the mobility rate):
–Under light traffic load, the single-sender scenario has
a lower PDR than the
multiple-sender scenario, yet the reliable protocol version does not recover from the single-transmitter
losses (as static network results
show, PDR of 100% is possible)
•Reliable BCAST performs worse under heavy traffic loads (many multicast sender sending lots of data)
–Under heavy traffic load, the increase in the number of
senders caused severe
congestion, producing a significant drop in PDR for all mobility rates and protocol versions.
