Analysis of a receiver-based reliable broadcast approach for vehicular networks

Abstract

The Intelligent Transportation Systems concept provides the ground to enable a wide range of applications to improve traffic safety and efficiency. Innovative communication systems must be proposed taking into account, on the one hand, unstable characteristics of vehicular communications and, on the other hand, different requirements of applications. In this paper a reliable (geo-)broadcasting scheme for vehicular ad-hoc networks is proposed and analyzed. This receiver-based technique aims at fulfilling the received message integrity yet keeping the overhead at a reasonably low level. The results are compared to simulation studies carried out in the Network Simulator-3 (NS-3) simulation environment demonstrating good agreement with each other. The analysis shows that in a single-hop scenario, receiver-based reliable broadcasting can provide good reliability, while giving very little overhead for high number of receivers.

Towards reliable multi-hop broadcast in VANETs: An analytical approach

“…other nodes send the same request or reply that is overheard by the node backing off to send it). For further detail regarding its functionality, we refer to our work in [9]. It is worth pointing out that here we assume that the underlying ETSI/ITS standard geo-networking infrastructure [5] is functionally available, as the basis to implement such a reliability mechanism.…”

“…In our work in [9] [10], we analytically modeled and evaluated a receiver-based end-to-end reliability assurance mechanism for vehicular networks in the context of singlehop (geo-)broadcast. This mechanism, which is described in Section III, enables loss detection and correction by means of sequence numbering and checking at communicating parties, as shown at high-level in Figure 1 and is suitable for various ITS applications, demanding strict requirements on delivery assurance.…”

Analysis of a receiver-based reliable broadcast approach for vehicular networks

“…The main contributions of this paper are as follows: (i) we extend the end-to-end (geo-)broadcast reliability assurance mechanism, originally proposed in the framework of the MO-BILITY 2.0 FP7 project [2], (ii) we propose an analytical model for performance evaluation of the functionality of the proposed protocol and validate it using the NS-3 network simulator [14], (iii) we derive system-oriented performance measures, with a significantly extended set of results, compared to the first version of this work [7], which has been published in IEEE Vehicular Networking Conference 2014 (VNC).…”

A Self-Adaptive and Link-Aware Beaconless Forwarding Protocol for VANETs

“…However, the nonuniform distribution of nodes, the high mobility, and dynamic nature of VANETs pose great challenges [10, 11] in reliable data transmission. Therefore, the reliable transmission requires efficient routing protocol [12] to lower the packet loss and the delay to meet the high requirement of QoE.…”

“…In SBF scheme, the sender selects the next forwarders according to routing state tables which need the HELLO or beacons to be maintained and updated periodically; so the overhead in SBF is always higher. On the contrary, in RBF, the next forwarder is chosen according to the contention of the receiving node, in which the overhead is reduced because it does not need to maintain and update routing tables [12, 16].…”
