Delay-Tolerant Networks (DTNs) are special types of network environments that are subject to delays and disruptions. Traditional end-to-end routing fails in DTNs due to intermittent connections. The authors apply the concept of DTN to vehicular environments, and propose a new routing protocol that applies both diversity and accuracy in routing decisions. Their proposed routing has one excellent feature that supports its use for a distributed location discovery service. They evaluate this routing, using a real street map, in terms of different performance aspects. Experimental results show the superiority of this protocol over other existing ones.
