Fast Broadcast modules for NS-2
no vote
Problem:
Applications such as online gaming and alert message
propagation are sensitive to per-packet delivery delays. Consider a Vehicular
Ad-hoc Network (VANET); in this context, the quick propagation of multi-hop
broadcast messages generated by the aforementioned applications requires the
deployment of specific solutions able to avoid redundant transmissions and other
sources of message propagation delays.
Solution:
We have
developed a solution that allows vehicles in a car platoon to dynamically
estimate their transmission range and to exploit this information to efficiently
propagate a broadcast message with as few hops (and transmissions) as possible.
In essence, the farthest vehicle in the transmission range of a message
sender/forwarder will be statistically privileged in becoming the next (and
only) forwarder.
