This paper develops a new analytic model for the performance and reliability analysis of safety-related message broadcast in vehicular ad hoc networks (VANETs) at rural intersections. First, a semi-Markov process (SMP) model for characterizing channel behavior of IEEE 802.11 based VANET is deployed to interact with the M/G/1 queue through fixed-point iteration. Then, the mean transmission delay between...
In this paper, an analytic model is proposed for the performance evaluation of vehicular safety related services in the dedicated short range communications (DSRC) system on highways. The generation and service of safety messages in each vehicle is modeled by a generalized M/G/1 queue. The overall model is a set of interacting M/G/1 queues, one queue for each vehicle. The interaction is that the server...
