Evaluation of greedy perimeter stateless routing protocol on vehicular ad hoc network in palembang city

Vehicular Ad Hoc Network (VANET) is a Mobile Ad Hoc Network (MANET) concept where the vehicle acts as a node on the network. VANET uses a mobile vehicle in the Ad Hoc based wireless network. Therefore, VANET is a development of wireless networks have a protocol-specific routing implementation within the network. In this paper, we will analyze correlation queue length and time in the position-based routing, Greedy Perimeter Stateless Routing (GPSR). The simulation is using Network Simulator 3 (NS3) and Simulation of Urban Mobility (SUMO). The scenarios are node count and velocity in the urban environment in Palembang. We propose a queue parameters (queue length and time) in the GPSR protocol in order to produce better performance. The result, by increasing the existing GPRS attributes (queue length is 96 byte and queue time is 45 seconds) made the GPSR performance better in PDR, throughput and packet loss. While for end-to-end delay results, this parameter values have minimum performance.
