Secure Data Integrity in VANETs based on CS-DC Scheme

Wireless ad hoc networks (WANETs) have become increasingly popular in our everyday business and personal lives. Thus, users should be aware of the security risks associated with wireless technologies such as Vehicular Ad Hoc Networks (VANETs) which rely on nodes forwarding each other's packets. Then, without any security measures in place, any node is capable of compromising integrity of the data it forwards. In this paper, we integrated Hamming code into Compressive Sensing-Data Compression (CS-DC) scheme to detect and drop any malicious data quickly for protecting data integrity in VANETs and also, reducing the cost of communication overhead and avoiding Road Side Unit (RSU) deception. The performance of the proposed scheme shows the capability of protecting data integrity and the improvement of data transmission criteria and reduction of communication overhead in the presence of malicious nodes in VANETs.
