Abstract
OLSR (Optimized Link State Routing Protocol) adalah sebuah protocol link-state routing yang proactif. OLSR mempunyai 2 buah dan mengandalkan pemilihan node MPR (Multi Point Relay) dalam pengiriman sebuah pesan. MPR adalah beberapa node yang telah dipilih dengan kriteria tertentu yang bertugas untuk meneruskan sebuah pesan. Namun posisi dari MPR tersebut tersebar dengan acak, sehingga ada kemungkinan sebauh pesan akan drop atau tidak dapat sampai ke node tujuan dikarenakan node MPR tersebt terlalu jauh dengan node asal maupun node tujuan. Berdasarkan permasalahan tersebut, maka dilakukan penelitian terhadap kinerja protokol OLSR dengan menambahkan algoritma PGB (preferred Group Broadcasting). PGB adalah metode pengiriman sebuah pesan hanya kepada node yang berada pada area tertentu saja. Diharapkan dengan ditambahkannya PGB pada OLSR akan menjamin sebuah pesan akan sampai kepada node tujuan dan tidak mengalami storm broadcasting. Simulator yang digunakan pada uji coba adalah NS2. Diharapkan dari uji coba yang dilakukan akan diketahui bagaimana efek yang diberikan oleh PGB pada OLSR dengan menghitung nilai PDR (packet Delivery Ratio), End-to-End Delay dan TC (Topology Control).
========================================================================================================OLSR (Optimized Link State Routing Protocol) proactive protocol. OLSR has 2 kind of control,"HELLO" and "TC" and relied on MPR (Multi Point Relay) to sending a message. MPR is some nodes that have been selected with certain criteria which served to pass on a message. However, the position of the MPR is scattered with randomly, so there is a possibility of obstruction message will drop or can not get to the destination node because the node MPR too far with the source node or with the destination node. Based on these problems, then do research on the performance of OLSR protocol by adding algorithms PGB (preferred Group Broadcasting). PGB is a method of sending a message only to nodes that are in a particular area. PGB is expected with the addition of the OLSR will guarantee a message will get to the destination node and prevent storm broadcasting problem. Network simulator that is used to conduct this study was NS-2. It is expected from the experiments performed will be known how the effect given by the PGB on OLSR by calculating the value of the PDR (Packet Delivery Ratio), End-to-End Delay and TC (Topology Control).
