Infrastructure-assisted geo-routing for cooperative vehicular networks

Abstract

Abstract-Cooperative vehicular systems require the design of reliable and efficient multi-hop networking protocols to achieve their foreseen benefits. Although many geo-routing protocols have been proposed in the literature, few contributions have analysed the benefits that road side infrastructure units could provide to successfully route data from source to destination. In this context, this paper proposes a novel infrastructure-assisted routing approach designed to improve the end-to-end performance, range and operation of multi-hop vehicular communications by exploiting the reliable interconnection of infrastructure units. The conducted investigation shows that the proposed infrastructureassisted routing approach achieves its objectives, and reduces the routing overhead compared to other greedy position-based geo-routing protocols. Finally, the paper shows that to obtain the maximum benefits from the proposed infrastructure-assisted routing approach, optimal infrastructure deployment strategies must be further investigated.

“…A virtual infrastructure using buses is presented in [51], while a secure infrastructure is proposed in [46]. When considering vehicle-to-infrastructure communication, we notice works addressing the scheduling [27], real-time communication [40,41], delivery in sparse networks [42], analysis of connectivity [82][83][84], broadcast protocols [20], and cooperative georouting [43].…”

“…Borsetti and Gozalvez [43] propose an infrastructureassisted routing approach designed to improve the end-toend performance, range, and operation of multihop vehicular communications by exploiting the reliable interconnection of infrastructure units. The infrastructure is wired-connected and uses the position of each vehicle to route the data.…”

Unicast Routing on VANETs

“…Authors in [4] have proposed an infrastructure-assisted routing protocol. The main benefits behind this approach is to reduce the routing overhead and improve the end-to-end performance.…”

Exploiting context information for V2X dissemination in vehicular networks

“…However, such dissemination schemes may pose energy cost and traffic scalability issues to network operators, currently facing a growing demand of mobile data services. Alternatively, the messages can be cooperatively relayed from vehicle to vehicle (V2V) through the VANET, optionally using opportunistic store, carry and forward techniques [4] [5], or leveraging the presence of Roadside Units (RSUs), which can serve as originators of the information, or as fixed relay nodes to passing by vehicles [6] [7]. Vehicular mobility poses the main challenge to such V2V dissemination strategies as it may induce strong network disconnections.…”
