We consider a particular category of the index coding problems in the network to vehicle (N2V) communication scenario where each vehicle possesses some messages as side information and demands all messages which it does not possess. Under this setup, a lower bound on the number of transmissions is determined. This work proposes the design of an optimal index code for a particular case of N2V communication where the side information is consecutive and present a practical VANET scenario, where the proposed index code (IC) could be applied. The proposed IC solution is independent of the field size and can operate in any field. We have applied index-coded modulation (ICM) over the proposed IC for noisy broadcasting on the AWGN broadcast channel for improved bandwidth efficiency. An algorithm is proposed to map the index coded vectors to constellation points in such a way that the benefit in the error performance can be achieved by a maximum number of vehicles. The simulation results show that ICM offers improved error performance compared to Gray coded modulation for many vehicles while not degrading the performance for others.
