Analytical Model for Connectivity in Vehicular Ad Hoc Networks

摘要: We investigate connectivity in the ad hoc network formed between vehicles that move on a typical highway. use common model vehicular traffic theory which fixed point highway sees cars passing it are separated by times with an exponentially distributed duration. obtain distribution of distances cars, allows us to techniques from queuing study connectivity. Laplace transform probability distance, explicit expressions for expected and expectation number platoon. Then, we conduct extensive simulation studies evaluate obtained results. The analytical present is able describe effects various system parameters, including road parameters (i.e., speed flow) transmission range vehicles, To more precisely effect connectivity, provide bounds using stochastic ordering techniques. Our approach based work Miorandi Altman, transformed problem distance into busy period equivalent infinite server queue. our results, along statistical data, understand networks.
