Abstract
Vehicular Ad-hoc networks (VANETs) are promising information-sharing technologies for modern intelligent transportation systems (ITS), in which information can be disseminated and shared among a group of moving vehicles through wireless communication devices. Previous data dissemination schemes for VANETs are unable to meet the requirements of effective and efficient data dissemination in VANETs due to the dynamic nature of the framework such as the intermittent connection between vehicles. A position relationship and RSU assistance (PR) data dissemination algorithm was proposed for opportunistic VANETs. Through making use of road side unit (RSU), position information and transfer probability to improve the performance of PR algorithm. Simulation results show that the data delivery ratio of PR protocol is improved, the number of network copy is controlled, and network overhead is reduced.
