摘要: | The transmission technology for intelligent transportation systems can typically classified into two categories, namely, road-to-vehicle communication (RVC) and inter-vehicle communication (IVC). This work proposes an adaptive QoS aware roadside base station assisted routing mechanisms to establish a routing path in IVC with assistance of roadside base station. A link failure prevention mechanism is employed to effectively construct alternative routing path required by the volatile network topology in vehicular ad hoc networks. Besides, a bandwidth consumption predictor is presented to avoid dropping data packets owing to inadequate bandwidth during handoffs. A PSO-tuned fuzzy logic system is proposed to compute the link break and congestion indicator in the route construction process. Simulation results demonstrate the effectiveness and feasibility of the proposed work. |
