Submission doc.: IEEE 11-10/1511r0 Company Confidential Fairness: STA with throughput zero (CWmin 15) Slide 7Chittabrata Ghosh, Nokia November 2011

Submission doc.: IEEE 11-10/1511r0 Company Confidential Effect of increasing load on througput with link adaptation (CWmin 15) Slide 8Chittabrata Ghosh, Nokia November 2011

Submission doc.: IEEE 11-10/1511r0 Company Confidential STA with zero throughput for varying CW Slide 9Chittabrata Ghosh, Nokia November 2011 Without RTS/CTSWith RTS/CTS

Submission doc.: IEEE 11-10/1511r0 Company Confidential Conclusions DCF is unfair and inefficient in terms of energy and throughput under heavy/bursty traffics Varying CW sizes does not solve the problem Slide 10Chittabrata Ghosh, Nokia November 2011
