BAB V KESIMPULAN DAN SARAN
V.2. Saran
Ada saran yang dapat dipertimbangkan untuk pengembangan pengujian pada protokol DSR dengan simulator NS2 yaitu :
1. Melakukan pengujian dan analisis lebih lanjut dengan parameter yang berbeda, misalnya sumber trafik yang berbeda seperti tcp atau parameter berubah yang berbeda misalnya kecepatan node, dll.
2. Menguji lebih lanjut mengenai interval paket dan ukuran paket yang diindikasikan memiliki pengaruh terhadap kinerja protokol DSR.
