LAMPIRAN 1

Proses Saat Menjalankan Simulasi NS-2

1. Hal yang pertama dilakukan adalah membuka “

command line”

_{pada OS}

Ubuntu 12.35. Dengan cara “Ctrl + Alt + T, apabila sudah dilakukan akan

terlihat seperti gambar berikut:

2. Pada “Terminal” ketik perintah “cd” yang berfungsi untuk masuk kedalam

folder yang telah dibuat. Pada simulasi ini nama folder yang digunakan

“webmapper”. Kemudian tekan “Enter”.
