Performance Analysis of ARQ Mechanisms in WiMAX Networks
Journal Title: International Journal of Computer Science and Communication Networks - Year 2011, Vol 1, Issue 2
Abstract
WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16 standards-based wireless technology, provides Broadband Wireless Access (BWA) for Metropolitan Area Networks (MAN). The Automatic Repeat reQuest (ARQ) mechanism in WiMAX uses a feedback channel for the confirmation of error-free packet delivery or for packet retransmission request. This method can increase network throughput when radio channel condition is worse. In this paper attempt has been made to study the effect of implementation of ARQ on the performance of WiMAX network through simulation. Simulation study has been carried out for WiMAX network with and without enabling ARQ. The performance is been compared by considering the performance metrics like throughput, delay and jitter
