  2. Table of Contents • Goal • Model • Three Scenarios • Metric • Result • Future work

  3. Goal • Mobility 환경에서 OLSR, AODV의 실제 성능 비교 측정

  4. Model • Mobility에 따른 network topology의 빈번한 변화를 node의 On/Off로써 모델화 • Node 간의 접근성 차단 • MAC Layer

  5. Three Scenarios • On/Off 빈도 • Offered load • Background CBR • 250m 소요시간0km/h infinite      5km/h 180 secs     10km/h 90 secs     50km/h 18 secs    100km/h 9 secs    150km/h 6 secs • Fixed: OL(300kbps)            BCBR (0 kbps) • Varied: On/Off frequency • Offered Load   - Fixed: On/Off Frequency (18secs)             Background CBR (0kbps)   - Varied: Offered Load 30, 50, 150, 300, 400 kbps • Background CBR   - Fixed: On/Off Frequency (18secs)             Offered Load 300kbps   - Varied: Background CBR 0, 50, 100, 150 kbps t/3secs -> t/3secs -> t/3secs ->     -----------------------------------------------      o o o -> x o o -> x x o      x x x -> o x x -> o o x     -----------------------------------------------      -> x x x -> o x x -> o o x -> o o o -> ..      -> o o o -> x o o -> x x o -> x x x -> ..     -----------------------------------------------

  6. Metric • Packet delivery fraction • 도착한 packet 수/ 보낸 packet 수 • Average end-to-end delay of data packets • 현재 packet 별로 측정 불가 • Normalized routing load • 현재 측정 불가 • Throughput • bps

  7. Result – Scenario 1

  8. Result – Scenario 1

  9. Result – Scenario 1 Iperf log

  10. Future Work • Link 단절 후 data transfer 재개까지 시간이 오래 걸리는 원인 파악 • Scenario 1, 2, 3 진행
