HRV: Hybrid Routing in Vehicular Networks
نویسندگان
چکیده
4 To improve the quality of wireless communication and extend the application of emerging net5 working paradigms in Vehicular Ad Hoc Networks (VANETs), we design a hybrid routing scheme 6 for VANETs, called HRV. It presents a holistic solution for inter-vehicle, vehicle-to-roadside, 7 and inter-roadside communications in hybrid urban networks. The combination of roadside unit 8 (RSU) resources and ad hoc networks involves a network coding based multicast routing for dense 9 VANETs, using maximum distance separation (MDS) code and local topology information from 10 the forwarding set to achieve robust communication and max-flow min-cut data transmission; an 11 application of opportunistic routing, using a carry and forward scheme, to solve the forwarding 12 disconnection problem in sparse VANETs; and a routing switch mechanism to guarantee quality 13 of service (QoS) in HRV under various vehicular network connectivity and roadside deployment 14 configurations. The performance of our hybrid routing schemes is evaluated using reliable VANET 15 experiments. 16 17
