In urban vehicular ad hoc networks (VANETs), the intersection-based routing scheme has represented its greater applicability and better efficiency to adapt to high and constrained mobility. How to make an accurate decision for street selection is a challenging issue due to the rapid topology changes in VANETs. In this paper, we propose a microscopic mechanism based on intersection records (MMIR) in...
Recent vehicular ad hoc network routing protocols have relied on geographic forwarding and careful selection of road segments as ways to reduce the impact of individual vehicle movements. This paper shows how a virtualization layer and a new protocol running on top of it —called VNIBR, intersection-based routing on virtual nodes—can achieve better performance than state-of-the-art approaches, enabling...
As is known, the intersection-based geographic routing protocol is a promising solution to the information dissemination in realistic city environments. Also, there exists a series of special issues for VANETs urban area. Aiming to tackle these issues, many such routing protocols have been proposed in academia. In this paper, we present four important issues for city scenarios which not only strongly...
Because of different characteristics, the performance of traditional mobile ad hoc networks (MANETs) routing protocols is demonstrated poor in vehicular ad hoc networks (VANETs). Therefore, many routing protocols have been designed for VANETs during past few years. Most of these protocols utilized vehicular traffic to find optimal routing paths in urban environments. Although choosing the road segments...
