Vehicular networks are vulnerable to many security threats. One of the security threats is Sybil attack, and traditional security solutions which are based on cryptography and centralized authority are insufficient to protect vehicular network from Sybil attacks. We present a lightweight solution for Sybil attacks based on received signal strength. Our scheme is lightweight enough to be used by independent vehicles without using centralized trusted third party and additional hardware like GPS. We show through the experiments that it is possible to detect Sybil attacks by using received signal strength of the neighboring vehicles.
