Abstract :
Adaptive modulation enables a WiMAX system to optimize the throughput based on propagation conditions. IEEE 802.16 (WiMAX) system support BPSK, QPSK, 16-QAM and 64-QAM and the access scheme is OFDM. This paper presents the performance of different variants of transmission control protocols with different modulation schemes when density of mobile nodes changes.
