Performance Evaluation of WiMAX Network under Various Modulation Techniques using Various Versions of TCP
Worldwide interoperability for Microwave Access (WiMAX) is based on 802.16d/e Orthogonal Frequency Division Multiplexing (OFDM) based adaptive PHYsical layer (PHY) layer. It provides wireless broadband to fixed and mobile terminals. Modulation techniques enable WiMAX to optimize. WiMAX supports BPSK, DPSK, 16-QAM and 64-QAM. This paper parents the evaluation of various modulation techniques to increase the reliability of WiMAX based networks using various versions of Transmission Control Protocol (TCP). The proposed model helps to investigate how delay and throughput vary in terms of network parameters in order to optimize the system.
