Road Condition Monitoring with Source Authentication in VANET

In recent technologies, it has been said that, to improve the travel efficiency and safety of transportation systems, vehicular ad-hoc network (VANET) has been used as the promising technology where each vehicle is able to collect and communicate the information about current road or traffic condition at a particular location using an embedded on-board unit with the help of distributed roadside units. Examples are: While detection of some accident, congestion, jam, etc., vehicles broadcast warning signals to the nearby vehicles which would give a better awareness to every nearby vehicles about the driving environment and these nearby vehicles would change the driving plan if needed. The VANET technology has gained great attentions from both industry and academics in the recent days
