With the emerging advancements in VANETs, preserving location privacy has become a vital requirement. Most of the privacy schemes focus on changing the pseudonyms after a certain interval of time or in some special scenarios (can be mix-context or mix-zone) to avoid linking messages. Due to pseudonym linking attacks, elementary methods of pseudonym changing are found inefficient to provide desirable protection or privacy. The spatiotemporal information contained in beacons makes vehicles traceable, and the driver's privacy is breached. In this paper, we propose a mechanism CCAPS, which is a combination of two previously proposed schemes CAPS and CPN. This scheme takes the advantages of these two mix-context schemes and combines them. We evaluate this scheme against a global multi-target tracking adversary using PREXT simulator, and we compare the performance of proposed mechanism against the CAPS and CPN schemes.
