Simulation and Performance Evaluation of WiFi and WiMAX using OPNET
Wireless Fidelity (WiFi) network is based on the IEEE 802.11 standard. Worldwide Interoperability for Microwave Access (WiMAX), based on IEEE 802.16, is a standard with similar principles. The main advantage of WiMAX over WiFi is that it covers larger areas and has higher data rates. WiMAX network operators provide WiMAX subscriber units that enable connection to the metropolitan WiMAX network ...
متن کاملPerformance Analysis of IPTV over Fixed Wimax
IEEE defines various modulation schemes for WiMAX i.e. QPSK, BPSK, 16 QAM and 64 QAM. This model will examine Internet Protocol Television (IPTV) performance over Fixed WiMAX system taking many combinations of digital modulation. The performance will involve many key system parameters, which will involve the variation in the path loss, video coding, different rated codes, scheduling service cla...
متن کاملPerformance Evaluation of WiFi and WiMax Using Opnet
IEEE 802.16e, mobile Wi-Max, is a wireless technology used to provide very high data rate over large areas to a large number of users where broadband is unavailable. WiMAX network operators provide WiMAX subscriber units that enable connection to the metropolitan WiMAX network while WiFi units are used for connecting local devices within homes or businesses. In this paper, we use OPNET Modeler ...
متن کاملEvaluating the Performance of IPTV over Fixed WiMAX
IEEE specifies different modulation techniques for WiMAX; namely, BPSK, QPSK, 16 QAM and 64 QAM. This paper studies the performance of Internet Protocol Television (IPTV) over Fixed WiMAX system considering different combinations of digital modulation. The performance is studied taking into account a number of key system parameters which include the variation in the video coding, path-loss, sch...
متن کاملPerformance Evaluation of QoS Parameters during WiMAX to WiMAX Handoff using NS2 and QualNet
Terminal mobility with Quality of Service (QoS) can be provided through efficient and seamless handoffs and handoff management procedures in 4G wireless access networks. The primary objective of this work is to analyze the handoff management procedures within a WiMAX access networks and to evaluate its impact on different QoS metrics such as Packet Loss, Throughput and End-to-End Delay. The per...
