Abstract :
WLAN (Wireless Local Area Network) as one of the network access to users
that operate using radio frequencies has some advantage over a LAN using using
an ethernet cable. WLAN network, or known as Wi-Fi (Wireless Fidelity) is already
implemented in many places such as home, school, Office, corporate and
educational institutes. Although Wi-Fi provides convenience to users in accessing
the internet but in using video streaming service still requires considerable
bandwidth. In this thesis analysed the performance of streaming video service on
802 .11n WLAN networks with parameters to be tested include delay and jitter,
throughtput. Testing is done using the software simulator NS-3 operating system
Ubuntu, which is simulated in some scenarios. Each scenario is differentiated based
on number of users and the packet size which is simulated within 5 minutes. The
value of the highest throughput amounted to 536,48 kbps, the lowest delay 16,82
ms, jitter lowest 0 ms. number of users very influential towards the value of QoS
can be seen from the decline in the value of the original 536,48 kbps throughput be
117,22 kbps, delay the ride originally 16,82 ms became 100,27 ms and jitter values
that originally 0,034 ms. 0,071 ms with the initial 10 user raised to 50.
