Abstract

Link duration determines the performance of many vehicular applications, especially for urban vehicular wireless communication networks. However, the theoretical analysis on link properties is always complicated, since parameters that should be considered include the inter-vehicle distance, the vehicle speed, the turning ratios in the intersection, the influence of traffic lights in the intersections, and the signal decay caused by the roadside buildings etc. To reduce the analytical complexity, most of the previous works proposed preliminary analysis on link duration property by considering some parameters. Even though some works considered all parameters, their assumptions on the parameters setting were somewhat ideal. For example, the events of meeting traffic lights for two consecutive vehicles in a communication route path were always assumed independent with each other, which is different from the actual situations. This paper proposes a discrete Markov process-based analytical model on link duration by considering a relatively complete set of parameters, including the influence of the inter-vehicle distance, vehicle speed, turning ratios in the intersection, traffic lights in the intersection, and the non-line-of-sight transmission for the intersection. Especially, the theoretical study on the link duration is based on a more realistic traffic lights scenario description model. Finally, simulations are carried to verify the accuracy of our analytical work.
