An evaluation of inter-vehicle ad hoc networks based on realistic vehicular traces

Abstract

Vehicular ad hoc networks (VANETs) using WLAN technology have recently received considerable attention. The evaluation of VANET routing protocols often involves simulators since management and operation of a large number of real vehicular nodes is expensive. We study the behavior of routing protocols in VANETs by using mobility information obtained from a microscopic vehicular traffic simulator that is based on the on the real road maps of Switzerland. The performance of AODV and GPSR is significantly influenced by the choice of mobility model, and we observe a significantly reduced packet delivery ratio when employing the realistic traffic simulator to control mobility of nodes. To address the performance limitations of communication protocols in VANETs, we investigate two improvements that increase the packet delivery ratio and reduce the delay until the first packet arrives. The traces used in this study are available for public download.

Coherent, automatic address resolution for vehicular ad hoc networks

“…AODV is a reference protocol for MANETs and has been the foundation for many implementations of topology-based routing protocols proposed for vehicular networks (Aswathy and Tripti, 2012) (Naumov et al, 2006). GBSR (Tripp Barba et al, 2013), however, is a novel proposal based on GPSR (Karp and Kung, 2000), which improves this protocol in terms of packet losses.…”

“…These conditions were considered in the configuration settings of the evaluation scenario we used in this work, which consider a unique and fixed destination. It is important to notice that these characteristics help to build end-to-end paths and to reduce the amount of signalling messages, which are some of the details considered in AODV-inspired protocols like (Aswathy and Tripti, 2012) where a cluster is created and only the leaders of the cluster can create routes; or in Naumov et al (2006), where nodes in promiscuous mode are able to detect better routes. Moreover, since AODV needs more signalling traffic than its enhancements.…”

Peer-to-Peer Overlay in Mobile Ad-hoc Networks

“…Coupling the query lag time with a smart selection of intermediate nodes for query rebroadcast may turn out to be very beneficial. As shown in [45], the Preferred Group Broadcasting (PGB) limits the network load through local, receiver-based decisions to rebroadcast a message. Intermediate nodes still wait for a lag time before rebroadcasting, however its length depends on the value of the signal-to-noise ratio (SNR) associated to the received message.…”

Reliable Routing for Roadside to Vehicle Communications in Rural Areas

“…V2V communication has been extensively studied [6], [7], [8], [9]. In [8], the authors evaluated the performance of a reactive routing protocol (AODV) and a geographic routing protocol (GPSR) based on realistic vehicular traces.…”

“…In [8], the authors evaluated the performance of a reactive routing protocol (AODV) and a geographic routing protocol (GPSR) based on realistic vehicular traces. They also presented the Preferred Group Broadcasting (PGB) strategy and the Advanced Greedy Forwarding (AGF) technique to enhance the performance of reactive and geographic routing respectively.…”
