摘　　要：在车联网VANETs(vehicle ad hoc networks)中,车辆的高速移动、有限的无线资源以及不稳定的信号强度,给转发节点的选择机制提出挑战。为此,提出基于模糊逻辑的转发节点选择FLFNS(fuzzy logic-based forwarder nodes selection)算法。利用模糊逻辑算法选择下一跳转发节点,通过模糊逻辑理论,利用车间距离、车辆移动以及链路质量信息选择最优的转发节点。仿真结果表明,与Fuzzbr算法相比,FLFNS算法的端到端传输时延降低近50%,数据包传输成功率提高了10%。In vehicular ad hoc networks(VANETs),due to vehicle movement with high speed,limited wireless resources and unstable signal strength,an efficient multi-hop forwarding of broadcast messages is a challenging problem.Therefore,fuzzy logic-based forwarder nodes selection(FLFNS)algorithm was proposed.A fuzzy logic algorithm was used to choose the next hop relay nodes.By using the fuzzy logic algorithm,the best relay node was chosen by taking inter-vehicle distance,vehicle velocity,and link quality into account.Simulation results show that end-to-end delay of the proposed FLFNS algorithm is reduced byabout50%,and the packet delivery ratio is improved by10%compared with Fuzzbr algorithm.
