  1. SURE 2006 Transmission Scheduling for Mobile Ad Hoc Networks with Multiple-access Interference Ankit Misra Indian Institute of Technology, Kanpur ankitm@iitk.ac.in Advisor: Dr. Harlan Russell

  2. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI • Presentation Outline • Background • New Network Model • Simulation Results • Conclusion

  3. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI • Background • Ad Hoc Networks • Scheduling Protocols • Energy to Interference-Noise Ratio (EINR) • Multiple-access Interference (MAI)

  4. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI • Background • Ad Hoc Networks • No Infrastructure Required • Self-configuring • Temporary • Useful in Disaster Management, Military Conflicts etc.

  5. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI • Background • Scheduling Protocols • Assigns Transmission Slots on Wireless Channel • Fairness • Adaptive • Collision-Free

  6. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI Background Multiple-access Interference - EINR vs. Unit Disk Model Unit Disk Model dI > dC dC dC dT dI EINR based Model Transmitter Receiver Interferer EINR > β

  7. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI Background Multiple-access Interference - EINR vs. Unit Disk Model Unit Disk Model dI > dC dT dI Transmitter Receiver Interferer EINR based Model

  8. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI Background Multiple-access Interference - EINR vs. Unit Disk Model Unit Disk Model dI > dC dT dI Transmitter Receiver Interferer EINR based Model

  9. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI New Network Model Multiple-access Interference - EINR vs. Unit Disk Model dT= 0.25dC dT dI Transmitter Interferer dI= 0.50dC Receiver Unit Disk Model  Transmission will Fail EINR based Model  Transmission will Succeed Better Utilization using EINR based Scheduling

  10. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI New Network Model Multiple-access Interference - EINR vs. Unit Disk Model dT= 0.90dC dT dI dI= 1.50dC Transmitter Receiver Interferer Unit Disk Model  Transmission will Succeed EINR based Model  Transmission will Fail Collisions may occur in Unit Disk based Scheduling

  11. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI New Network Model 2 3 1 4 7 8 9 6 5 Unit-Disk based Schedule EINR based Schedule

  12. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI New Network Model Transmission Scheduling Protocol based on EINR model • Link Status depends on MAI • Scheduling Constraints based on • Instantaneous Link Status • Adaptive Protocol for Updating Link Status

  13. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI Simulation Results Performance Metrics

  14. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI Simulation Results

  15. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI Simulation Results

  16. SURE 2006Transmission Scheduling for Mobile Ad Hoc Networks with MAI • Conclusion • Unit-Disk based Schedule is not collision-free. • Unit-Disk assumption lowers the re-usage of channel. • EINR based Schedule more Realistic and collision-free. • EINR based Scheduling Protocol has Better Utilization.
