Analisa Perbandingan Kinerja Video Streaming Pada Jaringan Wlan Ad-Hoc Dengan Menggunakan Trasnport Layer Protocol Standar : Tcp, Tcp Vegas, Dan Udp Menggunakan Ns-2

LAMPIRAN

Lampiran 1 : Step by step Instalasi Ubuntu dekstop 14.04 LTS
Masukan media instalasi ubuntu yang sudah dibuat. Kemudian atur
booting awalnya agar mengarah ke media instalasinya. Kemudian mulai boot,
tunggu saja loading yang ada sampai muncul pilihan seperti dibawah ini.



Try Ubuntu: Berarti mencoba mengoperasikan ubuntu tanpa harus
menginstalnya ke hardisk.



Install Ubuntu: Berarti kita siap menginstal ubuntu ke hardisk.

Karena kita ingin menginstalnya, maka kita pilih saja Install Ubuntu. Bahasa
biarkan saja English, atau Anda bisa sesuai keinginan Anda.

Pada bagian ini langsung saja pilih Continue.

Universitas Sumatera Utara

Kemudian pada bagian Installation Type pilih saja Something else, agar kita bisa
mengatur partisinya secara manual nanti.

Kemudian akan masuk ke bagian partisi. Disini akan terlihat seperti pada gambar
jika hardisk yang digunakan baru, belum terdapat partisi apapun sebelumnya. Klik
New Partition Table untuk mulai membuat partisi baru.

Universitas Sumatera Utara

Klik Continue saja.

Maka akan terlihat berapa besar kapasitas harddisk yang Anda miliki. Pada
gambar terlihat punya saya sebesar 8GB. Nantinya kapasitas sebesar ini akan saya
bagi menjadi dua partisi saja, yaitu



Partisi Root: Partisi ini merupakan tempat dimana Ubuntu akan terinstal.

Universitas Sumatera Utara



Partisi Swap: Partisi ini dibutuhkan untuk swap file dan akan digunakan jika
Ubuntu membutuhkan tambahan memori.



Partisi Home: Partisi ini bersifat opsional, kamu bisa menambahkannya atau
menjadikannya satu dengan Root. Home adalah lokasi tempat file pribadi
kamu tersimpan (music, pictures, documents, dsb).

Oke, jika sudah paham kita lanjutkan. Pilih bagian yang free space, kemudian klik
add atau tanda “+” seperti pada gambar.

Untuk partisi root saya meberi kapasitas sebesar 7 GB, Anda bisa sesuaikan
dengan kapasitas hardisk dan kebutuhan Anda. Tipenya Primary, Location
Beginning, Use as Ext4, mount point / atau “root”. Jika sudah klik Oke.

Universitas Sumatera Utara

Kemudian akan ada sisanya 1 GB, yang ini akan saya jadikan swap. Pilih bagian
free space, kemudian klik add.

Size 1GB, Type Logical, Location Beginning, Use as Swap Area. Klik oke jika
sudah.

Universitas Sumatera Utara

Setelah semua selesai dan sudah terbagi sesuai keinginan, klik Install Now.

Pada bagian ini, kita disuruh menentukan dimana lokasi kita. Saya pilih Jakarta,
kemudian klik Continue.

Universitas Sumatera Utara

Pada bagian keyboard layout, biarkan default, kemudian klik Continue.

Universitas Sumatera Utara

Isi bagian ini sesuai keinginan Anda, kemudian Continue.

Universitas Sumatera Utara

Tunggu proses Instalasi yang sedang berlangsung, jika sudah selesai akan restart.

Masukan login dan password

Universitas Sumatera Utara

Jika sudah, Anda akan langsung dibawa menuju desktop ubuntu. Dan instalasi pun
sudah selesai.

# Test for 802.11 nodes.

# Scenario: Communication between MN and Sink Node with MN attached to
BS.
#

- Using grep ^r out.res | grep MAC | grep -c cbr you can see the number of

#

mac packets received at the destination (100 packets).

#
of

- Using grep ^s out.res | grep MAC | grep -c cbr you can see the number

#

mac packets sent. By default the scheduler uses 64QAM_3_4 for

#

modulation. Using lower modulation can result in packet fragmentation

#

so the number of packets sent can increase (ex. 402 using QPSK_1_2)

#

- Using grep "1 0 cbr" out.res | grep -c ^r shows the number of packets

#

received at the destination.
