Effect on RTT and throughput



• Ack filtering decreases the chances that the peer radio is busy, so backoffs are less frequent
• 2 wireless hops
  • Reno: mean RTT = 2.67 s, std dev = 1 s
  • AF: mean RTT = 1.85 s, std dev = 0.6 s
  • 25% higher throughput with AF (24 Kbps versus 19 Kbps)
• 3 wireless hops
  • 34% higher throughput with AF (17.1 Kbps versus 12.7 Kbps)
