    Abstract

    There are major challenges in establishing effective communications between nodes in vehicular ad hoc networks (VANETs) that are subject to disconnections, hinder end-toend source and target connection. Another problem arises when VANETs are sparse, whereby communication between vehicles occurs after long periods of time causing delays. In these environments, traditional routing protocols proposed for VANETs suffer holding continuous connection and performance problems. To overcome these problems, Delay Tolerant Networks (DTN) for Interplanetary Networks (IPN) routing protocols, which encourages applications to use a minimized number of round trips are considered suitable alternatives. They are designed for storing and forwarding messages when nodes can find other nodes to maintain end-to-end connections. In our previous work, we proposed a routing protocol VDTN-ToD based on DTN which uses a metric Trend of Delivery (ToD) scheme to assist in its routing and forwarding decisions. In our current work, we use this metric in order to provide better performance for DTN routing protocols Spray-And-Wait and PROPHET in VANETs. The results show that the inclusion of ToD in VANETs allows significant performance improvements and it can also be used in many other routing protocols to overcome performance issues.
