Unicast Ad-Hoc Routing in Vehicular City Scenarios
نویسندگان
چکیده
Within Vehicular Ad-Hoc Networking (VANET), i.e., networking between radio-equipped vehicles, unicast packet forwarding can be separated into the one-dimensional highway case and the two-dimensional city case. In this report, we survey the routing methods developed in the FleetNet [1] and Network-on-Wheels [2] projects plus a novel combination of two well-known methods called PBR-DV or Position-Based Routing with Distance-Vector recovery. On the quest for a city-capable candidate routing algorithm as a possible standard, we discuss the usability and performance of the protocols in city scenarios. Finally, we conclude proposing PBR-DV as a candidate protocol for small-hop-count unicast VANET scenarios.

Distributed Reinforcement Learning Approach for Vehicular Ad Hoc Networks
In Vehicular Ad hoc Networks (VANETs), general purpose ad hoc routing protocols such as AODV cannot work efficiently due to the frequent changes in network topology caused by vehicle movement. This paper proposes a VANET routing protocol QLAODV (QLearning AODV) which suits unicast applications in high mobility scenarios. QLAODV is a distributed reinforcement learning routing protocol, which use...
