Inter-Vehicle Communication System in a built-up city environment faces greater challenges because of potentially more uneven distribution of vehicular nodes, constrained mobility, and difficult signal reception due to radio obstacles such as high rise buildings. This paper proposes a new position-based routing scheme designed specifically for IVCS in a city environment and for the roadside equipment using a Cognitive Radio to allocate a multiple channel for communicating between vehicles to infrastructure to provide a safety message to avoid a emergency event.
