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.
