In this research, a new routing protocol called Multi-Copy Intersection-Based Routing (MCIR) is being proposed. MCIR is designed for Vehicular Ad-Hoc Networks (VANETs) in urban areas. MCIR is an intersection-based routing protocol that forwards multiple copies of the packets in different road segments. Moreover, it is a beacon-less routing protocol with a carry-and-forward strategy. We show via simulation that the MCIR protocol is superior to other existing routing protocols, especially in low vehicular density scenarios. The results show that MCIR achieves a shorter end-to-end delay and a higher packet delivery ratio in urban VANET communications. In addition, results show that MCIR outperforms SRPMT, AMR, and modified-GPSR in terms of the end-to-end delay and packet delivery ratio.
