A Four-State Markov Model Based on Measurements for Evaluating the Packet-Level Performance of VANET
Vehicular Ad hoc NETwork (VANET), a subclass of Mobile Ad hoc NETworks (MANETs), is a promising approach for future Intelligent Transportation System (ITS). Understanding and modeling packet error in the VANET is especially relevant to the design and analysis of higher layer wireless communication protocols. In this paper, the analysis of the packet error characteristics based on measurements in live VANET in different scenarios is shown form which Traces-4 are selected for further analysis. Based on the statistical dependence between burstlengths and gaplengths, they present a Packet-Level Markov (PLM) model which is capable of describing the measured statistics properly.
