Supporting Road Safety Warning and Advertisement Distribution using an Interest Area-aware Messaging Scheme in Vehicular Ad-hoc Networks

Current implementation of VANET-based road safety warning message and advertisement dissemination does not consider cooperation of other available helpful parties such as nearby establishments. This paper presents a communication scheme that can support both road safety warning (RSW) and advertisement dissemination that also considers the participation of an establishment-based Road Side Unit (eRSU) for message dissemination. To reduce message overhead and ensure prompt and effective delivery of RSW and advertisements, the proposed scheme utilizes an interest-area aware and destination probability of encounter metrics for vehicle to vehicle (V2V) message dissemination. The proposed work is compared with several dissemination protocols and simulation results show several significant advantages of the approach in terms of effective delivery rate, delivery time and message overhead.
