Duplicated information avoidance in vehicular ad hoc network

Broadcasting is a common method to discover a route or transmitting the messages in protocols designed in ad hoc networks. In order to propagate useful traffic information to other vehicles around, the way of broadcasting are adapt to the vehicular ad hoc networks (VANET). Nevertheless, the...
