Vehicular named data network (VNDN) has emerged as a promising network technology, where the focus of communication is moved from host-centric to information-centric. Since, the VNDN is at its early stage in development, there are several open issues to be explored and pending interest table (PIT) management is one of them. In VNDN, PIT stores each broadcasted interest until the required content is...
In this paper, we investigate the performance of OLSR and AODV protocols in a Manhattan grid scenario when sending triple TCP flow over FTP. We considered data rates of 0.1 Mbps and 1 Mbps. For the simulations, we used SUMO and NS3. We considered IEEE 802.11p standard and TwoRayGroundPropagationLossModel. We use through-put and cwnd as evaluation metrics. The simulation results show that for small...
In this paper, we investigate the performance of OLSR and AODV protocols in a VANET crossroad scenario. The mobility patterns of vehicles are generated by means of CAVENET (Cellular Automaton based Vehicular Network) and as communication protocol simulator, is used NS3(Network Simulator 3). For the simulations, we used IEEE802.11p standard, TwoRayGroundPropagationLossModel and sent multiple CBR flows...
In this paper, we investigate the performance of OLSR and DSDV protocols in a highway VANET scenario. The mobility patterns of vehicles are generated by means of CAVENET (Cellular Automaton based Vehicular Network). As communication protocol simulator, is used NS3 (Network Simulator 3). The simulations are done for four different scenarios based on nodes ID. We use Throughput and Packet Delivery Ratio...
In this work, we evaluate the performance of DYMO routing protocol in different VANET scenarios. We investigate the effect of density and speed in the performance of communication between nodes using different node densities and speeds for the same simulation area. As evaluation metric, we use Packet Delivery Ratio (PDR). The simulation results have shown that with the increasing of the nodes density...
In this paper, we propose a reliable routing scheme based on vehicle moving similarity (RR-VMS), which focuses on stable rebroadcast nodes selection and route discovery to make inter-vehicle data transmissions more reliable. We select nearby vehicles having similar velocities with the source vehicle as rebroadcast nodes. We call these vehicles having moving similarity with the source vehicle. To reflect...
Vehicular ad hoc networks (VANETs) are an important example of mobile ad hoc networks (MANETs) because they can save lives by improving safety on our road networks. They are difficult to design however due their inherent characteristics e.g., quickly changing topology, node density and relative speeds of vehicles. These characteristics also make current wireless media access control (MAC) protocols...
