Message Dissemination Scheme for Rural Areas Using VANET (Hardware Implementation)

Abstract

Vehicular Ad hoc NETworks (VANETs) are likely to play an important role in Intelligent Transport Systems (ITS). Information collected by On Board Units (OBUs) located in vehicles can help in avoiding congestion, provide useful information to drivers, etc. However, not all drivers on roads can benefit from OBU implementation because OBU is currently not available in all car models. Therefore, in this paper, we designed and built a hardware implementation for OBU which allows to disseminate messages in rural areas. This OBU implementation is simple, efficient, and at low cost. Evaluation results show that our proposed model can transmit and receive plaintext and encrypted messages (e.g., safety messages) to nearby vehicles, Access Point (AP), and destination with acceptable time.
