Abstract
Vehicular ad hoc network (VANET) is suffering from the frequent link breakage and low packet delivery rate, which challenges routing protocols. To address this issue, we propose a Geographic Opportunistic Routing protocol based on Link state and Forwarding quality inside nodes (LF-GOR). We first put forward a hybrid approach of filtering and prioritizing to determine a candidate nodes set of the sending node in LF-GOR, which considers not only position information but also link state and node's forwarding quality comprehensively. Based on the candidate nodes set, we design a flexible opportunistic forwarding strategy to involve multiple neighbors of the sending node into the local forwarding. Consequently, LF-GOR improves the reliability of transmission, and reduces the end-to-end delay brought by the timer-based scheduling mode of many normal opportunistic routing protocols. Finally, a comparison between LF-GOR and existing protocols is presented in the simulation. Corresponding results show that LF-GOR has the higher packet delivery rate and throughput, and also the acceptable delay.
