Performance Evaluation of TCP SACK1 in WiMAX Network Asymmetry
WiMAX is abbreviation 'Worldwide Interoperability for Microwave Access', is a new wireless OFDM based technology that provides high throughput broadband connection over long distances based on IEEE 802.16. The WiMAX technology support to different channel bandwidth, cyclic prefix, modulation coding scheme, frame duration, simultaneous two way data transfer and propagation model. The WiMAX network asymmetry is largely depends on DL: UL ratio. This paper evaluate the performance of TCP Sack1 by considering channel bandwidth, cyclic prefix, modulation coding scheme, frame duration, Two way transfer and propagation model in WiMAX network with network asymmetry.
