Abstract

One implementation of a wireless network is a very popular wireless networking technology Local Area Network (WLAN) or better known as Wireless Fidelity networks (Wi-Fi). Network performance qualified and good performance on network technology Wireless Fidelity (Wi-Fi) is influenced by many factors. Factors affecting the movement of the user approaching the access point and the user away from access point when accessing the Internet using a Wi-Fi network at different speeds will have varying quality and performance. Factor of the user in turn influence the parameters of Quality of Service (QoS) in Wireless Fidelity network. Parameters of QoS on the network technology Wireless Fidelity (Wi-Fi)are delay, jitter, throughput. QoS obtained from the movement of the user in the network WiFi can be determined from that simulation software OPNET Modeler was designed in 14.5. Observation of the effect of user mobility on the QoS parameters in Wifi performed on HTTP, FTP, and video conferencing. The simulation results of the threespeed mobility, the highest value of the parameter packet loss, delay, jitter at a speed of 1.6 m/s and the highest value of the parameter throughput at speeds of 0.6 m/s. The highest value of packet loss on the FTP service amounting 0.011590307%, the HTTP service amounting 0.009656612% and video conferencexxvi services amounting 0.654249439% based on the ETSI standardization included in the range of 0% - 3% with very good category. The highest value of the delay parameter amounting 1.199224675 ms based on the ETSI standardization included the target value 150 ms with very good category. The highest value of delay variation parameters amounting 7.007708769 ms based on the ETSI standardization included the target value of <75 ms with a very good category. Throughput parameter has the highest value amounting 165,582.4854 bps included in the standardization 802.11g with the value of the maximum throughput amounting 24700000 bps. Key Words : Wireless Fidelity (Wi-Fi), mobility, delay, jitter, throughpu
