Relating Simulation and LP Results
nMaximum AODV throughput: 178 kbps (for 15 sender/flows)
nLP: Maximum throughput 1.2 – 1.8 times LINK_BW (2 Mbps), depending on node distribution and min flow constraint
nNaïve Interpretation: Huge Gap (7.5 % of LP result)
nMore Detailed Analysis:
ØMAC Overhead (analytical results): saturation throughput
only 40% of LINK_BW for
packet size, number of neighbors
ØAccounting for routing protocol overhead (50% of all MAC
transmission)
ØLost packets also consume network resources: 15 sender
generate aggregate of 300 kbps,
only 178 kbps received. If packets are, on average, dropped midway, corresponds to 61 kbps of
end-to-end traffic
