Each experiment measures throughput between 65 randomly
selected node pairs. First, the nodes broadcast 1500-
byte packets every ten seconds for ten minutes and report
the measured delivery probabilities from all other nodes to
a central server. The server distributes this information
to all the nodes. The measurements are used to compute
ETX metrics and traditional routes. Next, the server contacts
each of the 65 node pairs in sequence, telling the pair
to measure the time required to transfer a 1.0 megabyte
¯le using traditional routing, then to wait 15 seconds, then
to measure the time required to transfer 1.1 megabytes using
ExOR. The evaluation does not use the combination of
ExOR and traditional routing, so the extra 0.1 megabyte is
to compensate for the 10% of packets which may not have
been delivered ordinarily. The reported throughput is one
megabyte divided by the total time required to transfer the
data. Every twenty minutes, the central server suspends the
experimental runs to recollect the link loss measurements.
During the experiment, existing Roofnet routing and user
tra±c are present.
