Over the last few years, VANETs have turned into an important research area. For the roadside equipment, Cognitive Radio protocol allocates multiple channels simultaneously to improve the delay incurred in an emergency situation, thereby providing safety vehicular- infrastructure message communication. In a city environment, due to an uneven distribution of Inter-Vehicle Communication System (IVCS) faces great challenges such as high rising buildings. The proposed scheme position-based routing (A-STAR) extends the WSN lifetime which supports dynamic status update on sinking neighbor’s energy levels. Thus the overall network lifetime gets extended which depends on this energy consumption.
