Abstract
Vehicular Ad hoc Network (VANETs) adalah teknologi komunikasi yang menggunakan jaringan ad hoc untuk berkomunikasi. Pengembangan VANETs berfokus kepada routing protocol yang dinamis yang dapat bertahan pada lingkungan VANETs yang cepat dan tidak terprediksi. Greedy Perimeter Stateless Routing (GPSR) merupakan salah satu protokol dalam VANETs yang bekerja secara geographic. Pengiriman paket data dilakukan secara greedy berdasarkan posisi node tetangga menuju node destination. Oleh karena itu, dibutuhkan proses route discovery agar GPSR bisa mendeteksi ketersediaan rute menuju node destination.
GODV adalah modifikasi dari GPSR yang mengadopsi proses route discovery pada Dynamic Source Routing (DSR). Sebelum melakukan pengiriman paket data, node sumber mengirimkan paket route request menuju node destination. Lalu node destination akan merespon dengan mengirimkan paket route reply kembali node sumber dengan menyimpan titik-titik rute pengiriman paket data yang digunakan sebagai implementasi konsep overlay network.
Hasil pengujian yang dilakukan menunjukkan bahwa GODV memberikan nilai rata-rata packet delivery ratio (PDR) yang lebih baik dibandingkan dengan GPSR dengan kenaikan rata-rata PDR sebesar 40 %.

The Vehicular Ad hoc Network (VANETs) is a communication technology that use an ad hoc networks to communicate. The main focus on VANETs development is to make a dynamic routing protocol that can survive in VANETs environment which is fast and unpredictable. Greedy Perimeter Stateless Routing (GPSR) is one of VANET’s protocol which is geographically based. Data packets greedily forwarded based on neighbors node position toward the destination. Hence, route discovery process is necessary to detect route availability toward the destination.
GODV is a modification of GPSR that adopt the route discovery process of Dynamic Source Routing (DSR). Before sending data packet, the source node broadcast route request to find the destination node. Then it responds by sending back a route reply to the soure node while recording all the point of routes that will be used as an implementation of overlay network concept for data packet forwarding.
The experiment result show that the average packet delivery ratio (PDR) of GODV improves 40% than GPSR.
