    1. A Single-Channel Solution for Transmission Power Controlin Wireless Ad Hoc Networks Alaa Muqattash and Marwan Krunz University of Arizon MobiHoc 2004 Presenter :gigigi

    2. Outline • Introduction • Motivation • Power control MAC protocol (POWMAC) • Detail • Simulation environment and results • Conclusions

    3. Introduction - IEEE 802.11 D C F E B A

    4. Motivation - Power Control D C F E B A

    5. POWMAC – RTS(MAX) D C F E B A

    6. POWMAC – CTS (adjustable) D C F E B A

    7. POWMAC – DTS(MAX) D C F E B A

    8. POWMAC – Access Window D C F E B A

    9. POWMAC - DATA(adjustable) D C F E B A

    10. POWMAC - ACK (adjustable) D C F E B A

    11. POWMAC

    12. Details • The maximum tolerable interference (MTI) of node u, denoted by • Channel gain Gi ubetween nodes i andu

    13. Details - RTS • the maximum allowable TP that node i can use without disturbing any of its neighbors

    14. Details - RTS

    15. Details - CTS

    16. Details - CTS

    17. Details - CTS

    18. Details - DTS

    19. Details - ACK • FEC code • the same power level that would have been used if i were to send a data packet to j.

    20. Simulation parameters

    21. Simulation environment

    22. Simulation result

    23. Simulation result

    24. Simulation result

    25. Simulation environment - Random Grid • 16 mobile nodes • square area of length 1500 meters. • The square is split into 16 smaller squares

    26. Simulation result - Random Grid

    27. Simulation result - Random Grid

    28. Simulation environment - Clustered • 600 × 600 • split into 4 equal groups, each occupying a 100 × 100 square in one of the corners of the complete area

    29. Simulation result - Clustered

    30. Simulation result - Clustered

    31. Conclusion • Single transceiver and single channel • Improve the network throughput by up to 45% in random grid topologies and much more than that in clustered topologies.
