چکیده    The vehicular ad hoc network (vanet) for intelligent transportation systems is an emerging concept to improve transportation security,reliability,and management. the network behavior can be totally different in topological aspects because of the mobility of vehicular nodes. the topology can be fully connected when the flow of vehicles is high and may have low connectivity or be invalid when the flow of vehicles is low or unbalanced. in big cities,the metropolitan buses that travel on exclusive lanes may be used to set up a metropolitan vehicular data network (backbone),raising the connectivity among the vehicles. therefore,this paper proposes the implementation of a living mobile backbone,totally ad hoc (mob-net),which will provide infrastructure and raise the network connectivity. in order to show the viability of mob-net,statistical analyses were made with real data of express buses that travel through exclusive lanes,besides evaluations through simulations and analytic models. the statistic,analytic,and simulation results prove that the buses that travel through exclusive lanes can be used to build a communication network totally ad hoc and provide connectivity in more than 99% of the time,besides raising the delivery rate up to 95%. © 2015 joilson alves junior and emilio c. g. wille.
