Certificate revocation schemes for providing secure QoS in MANETs

Summary Due to crucial exchange issues, security in mobile ad hoc networks (MANETs) is more complicated. It is vital to secure MANET exchanges to ensure the network's services development. In this research, the proposed model focuses on providing trust and certificate‐based Malicious Node detection for mobile adhoc networks and improving certificate revocation based on cluster head. The cluster head is crucial in eliminating falsely accused nodes. The malicious node may be easily discovered and isolated from the network using the trusted value. If the trust value falls below the trust threshold value in a trust management, the node is identified as malicious, the certificate is canceled, and the node is isolated from the network. The TSQRS protocol's integration with the CRS scheme was the main emphasis of the suggested model. The proposed model also creates more stable clusters with the help of Trust manager. When compared to other current protocols and methodologies, the findings produced by the suggested approach for the TSQRS‐CRS scheme improve performance and stability in the QoS of MANETs. Finally, certain parameters were used to run the simulation, which resulted in an improved Packet Delivery Ratio, Routing Overhead, and reduced Delay.
