面向高速公路环境的VANETs中V2V链路时延的动态预测
Dynamic prediction of V2V link duration in VANETs for highway environments
摘要
Abstract
A mathematic model for dynamic prediction of link duration (DPLD) in vehicular ad hoc networks (VANETs) is proposed because existing methods for theoretical analysis of link duration in both mobile ad hoc networks (MANETs) and VANETs are too complicated to be applied to a practical setting. The practical DPLD model considers the distribution of two vehicle’s relative velocity, inter vehicle distance and traffic density to estimate the expected link duration between any pair of connected vehicles. The implementation of the model depends on an approach for relative velocity estimation, an exponential moving average (EMA) based data processing procedure, and the solving of the impact of the traffic density on link duration by processing the velocity change of vehicles. The simulation results show that the DPLD model can predict link duration with the high accuracy.关键词
