Abstract
Vehicular Ad hoc Networks (VANETs) merupakan salah satu teknologi yang banyak dikembangkan di berbagai Negara. Fokus utama penelitian VANETs adalah routing protocol. Ada banyak routing protocol yang dapat diimplementasikan pada VANETs salah satunya adalah Ad-Hoc On Demand Distance Vector (AODV). AODV merupakan salah satu routing protocol yang termasuk dalam klasifikasi reactive routing protocol. Sebuah routing protocol yang hanya akan membuat rute ketika ada paket yang ingin dikirim.
Pada Tugas Akhir ini akan dilakukan modifikasi pada proses forwarding node yang dinamis pada route discovery berdasarkan jumlah threshold pada active route pada routing table, yaitu dengan cara mengeliminasi jumlah forwarding node yang bertugas untuk mengirim ulang (re-broadcast) RREQ dengan batas Threshold active route pada routing table. Hal ini dilakukan agar dapat meningkatkan kinerja protokol AODV untuk mencari rute yang stabil dengan cara memodifikasi beberapa bagian dari mekanisme pengiriman paket RREQ. . Modifikasi yang dilakukan akan menghasilkan routing overhead dan forwarded route request yang lebih kecil daripada routing protocol AODV yang asli.
Pada tugas akhir ini, performa pada routing protocol AODV yang telah dimodifikasi menghasilkan performa yang lebih bagus. Dibuktikan dengan skenario real yang menghasilkan peningkatan rata-rata packet delivery ratio sebesar 1.65%, rata-rata penurunan routing overhead sebesar 6.84%, rata-rata penurunan end to end delay sebesar 67.10%, dan juga rata-rata penurunan forwarded route request sebesar 70.74%.
================================================================================================
Vehicular Ad Hoc Network (VANET) is one technology that has been developed in various countries. The main focus of research VANET is a routing protocol efficiency. There are many routing protocol on VANETs, one of them is Ad-Hoc On Demand Distance Vector (AODV). AODV is classified to reactive routing protocol. A routing protocol that only make the route when there are pakets to be sent.
In this final project, modification will be made in forwarding node process on AODV routing protocol based on the number of threshold on active route in routing table. By looking at the number of neighbor node and the number of routing table of each node, and then if the number of neighbor nodes and the number of routing table less than threshold, the node becomes a forwarding node and the node will rebroadcast the packet. This is done to improve the performance of the AODV routing protocol to find a stable route by modifying some parts of the RREQ packet delivery mechanism.
The evaluation shows that the performance of the modified protocol has a better result than the original routing protocol AODV.. It is proven that in real scenario, there is an enhancement of average packet delivery ratio by 1.65%, reduction of average routing overhead by 6.84%, reduction of average end to end delay by 67.10% and reduction of average forwarded route request by 70.74%
