Abstract: Along with the prime aim of providing on-road safety, vehicular ad hoc networks have enabled the infotainment applications due to increasing demands from various travellers. The high mobility of nodes demands fast and efficient broadcasting of data. In this paper, we use index coding with clustering and cooperative downloading to satisfy various demands of travelling vehicles in reduced number of transmissions. The proposed index coding based protocol achieves better download throughput through V2V data exchange between clusters. Simulation results show that the proposed design achieves higher throughput than previously defined IEEE 1609.4 and Vehicular Enhanced Multichannel MAC (VEMMAC) protocols by reducing the total number of transmissions at the server.

Keywords: clustering; cooperative communication; index coding; VANETs.
