An Efficient and Secure Malicious User Detection Scheme Based on Reputation Mechanism for Mobile Crowdsensing VANET

Table 1

Comparison of research literatures.

Research categories	Advantages	Disadvantages
Cryptography [20–22]	The credibility of user is guaranteed.	The sensing data quality cannot be guaranteed; the overhead is too large.
Incentive mechanism [23–26]	The credibility of user and effective evaluation of data are guaranteed.	The user fairness cannot be guaranteed; the practicality of the scheme is poor.
Reputation mechanism [27–31]	The reputation of user is evaluated from multiple aspects.	The historical reputation is not fully considered; the user fairness and the accuracy of detection methods cannot be guaranteed.
