Abstract
Jaringan Delay Tolerant Network(DTN) dikembangkan berdasarkan
kondisi jaringan yang tidak menitikberatkan kepada end-to-end connection seperti
jaringan pada umumnya. Setiap node pada lingkungan jaringan DTN berfungsi
sebagai router dan memiliki storage yang digunakan untuk menyimpan pesan.
Protokol routing pada lingkungan DTN lebih menekankan kepada seberapa besar
pesan yang dikirimkan dari source node sampai kepada destination node. Protokol
routing epidemic bekerja dengan melakukan flooding pesan pada jaringan, dengan
tujuan agar pesan cepat sampai pada destination node tanpa melihat aspek
overhead ratio dan delay yang dihasilkan. Protokol routing Spray and Wait(SaW)
memperbaiki kinerja dari protokol epidemic dengan membagi dua fase yaitu fase
spray dan wait. Protokol SaW mengurangi overhead ratio yang dihasilkan dari
protokol routing epidemic. Protokol The Different-Neighbour History Spray and
Wait(DNH-SaW) melakukan modifikasi pada protokol routing SaW dengan
menambahkan performa histori node yang ditemui dengan tujuan untuk mengatur
jumlah banyaknya salinan pesan yang diberikan kepada node relay untuk
diteruskan kepada destination node.
Pada protokol routing DNH-SaW penentuan forward strategy message
hanya terfokus pada jumlah node yang ditemui, akan tetapi mengabaikan faktor
seberapa banyak frekuensi pertemuan di dalam histori serta kecepatan node.
Dengan memperhatikan frekuensi pertemuan dan kecepatan node, memungkinkan
fase spray berubah dan masuk ke tahap fase wait.
Hasil penelitian menunjukkan bahwa pengaruh terhadap performa node
histori, frekuensi dan kecepatan dapat meningkatkan delivery ratio pengiriman
pesan dan penurunan terhadap latency pada protokol DNHSaWNew, tetapi
memberikan efek yang jelek terhadap peningkatan overhead ratio yang
dihasilkan.
============================================================
Network Delay Tolerant Network (DTN) is developed based on network
conditions that do not prioritize the end-to-end connection such as a network in
general. Each node on the network environment DTN serves as a router and have
storage that is used to store messages. DTN routing protocols on the environment
it is more about how large a message sent from the source node to the destination
node. Epidemic routing protocol works by flooding a message on the network,
with the aim that the instant messages to the destination node without seeing
overhead aspect ratio and the resulting delay. The routing protocol Spray and
Wait (SAW) improve the performance of the protocol epidemic by dividing the two
phases which spray and wait. Saw protocol reduces the overhead ratio resulting
from routing protocol epidemic. The protocol-Neighbour History Different Spray
and Wait (DNH-SAW) make modifications in the routing protocol performance
history SAW by adding nodes encountered with the aim of regulating the amount
of the number of copies of the messages given to relay nodes to be forwarded to
the destination node.
In the DNH-Saw routing protocols determine message forward strategy
focused only on the number of nodes encountered, but ignore the factor of how
much the frequency of meetings in history as well as the speed of the node. Having
regard to the frequency of meetings and the speed of the node, enabling spray
phase change and entered the stage of phase wait.
The results showed that the influence of the node performance history,
frequency and speed of delivery can improve message delivery ratio and
decreased the latency in protocols DNHSaWNew, but give bad effect to the
increased overhead ratio is generated.
