This work suggests a novel OR technique for Vehicular Ad-Hoc Networks (VANets) to overcome the routing problem in VANETs using Dijkstra Algorithm with binary heap for candidate selection and finds that the time complexity of candidate selection is more efficient compared to existing schemes.Abstract:
The Opportunistic Routing (OR) in a dynamic vehicular network increases the wireless network performance. It advantages from the broadcast nature of vehicular nodes to progress performance of the network. The primary responsibility of Opportunistic Routing is its capability to hear the communicated message and to manage among relaying vehicular nodes. In this work, we suggest a novel OR technique for Vehicular Ad-Hoc Networks (VANETs) to overcome the routing problem in VANETs. In this work, we concentrate on our consideration around the incorporation of Vehicular networks and Opportunistic Routing, which is the concept that we call as Vehicular Opportunistic Routing. To deal with the dynamic nature of vehicular node, we have recommended a innovative performance measure which reflects the location of the dynamic vehicular nodes, the link delivery probability(LDP) between the dynamic vehicular nodes, the number of the neighboring vehicular nodes in the highway/intersection, and the predicted current position of the highly dynamic vehicular nodes. We compared our proposed scheme with existing Opportunistic Routing schemes, and verified that our scheme performs better in message/packet delivery ratio (MDR/PDR), end-to-end(E-2-E) latency, and expected number of transmissions(ETX) from the source vehicular node to the destination vehicular node in terms of the Manhattan Grid Mobility Model. In our proposed approach, we have used Dijkstra Algorithm with binary heap for candidate selection. Using this approach, the time complexity of candidate selection is more efficient compared to existing schemes.read more

An energy-saving routing algorithm for opportunity networks based on asynchronous sleeping mode
TL;DR: An asynchronous sleep mechanism is proposed, which allows nodes to judge whether to enter the sleep state according to their own energy situation, real-time state and other information and ensures that the nodes do not miss the possible communication opportunities by dynamically controlling the sleep time and wake-up time.

3DEOR: an opportunity routing protocol using evidence theory appropriate for 3D urban environments in VANETs
TL;DR: In this paper, the authors proposed a three-dimensional evidence theory based, opportunistic routing protocol, called 3DEOR, which addressed the above issues using a new hybrid criterion called PAL.

ExOR: opportunistic multi-hop routing for wireless networks
Sanjit Biswas,Robert Morris +1 more
TL;DR: ExOR chooses each hop of a packet's route after the transmission for that hop, so that the choice can reflect which intermediate nodes actually received the transmission, which gives each transmission multiple opportunities to make progress.

Trading structure for randomness in wireless opportunistic routing
TL;DR: More as mentioned in this paper is a MAC-independent opportunistic routing protocol, which randomly mixes packets before forwarding them to ensure that routers that hear the same transmission do not forward the same packets, thus, it needs no special scheduler to coordinate routers and can run directly on top of 802.11.

Performance evaluation of routing protocols for ad hoc wireless networks
TL;DR: The results indicate that despite its improvement in reducing route request packets, CBRP has a higher overhead than DSR because of its periodic hello messages while AODV's end-to-end packet delay is the shortest when compared to DSR and CBRP.
