Enhancing Wireless sensor network security with Trust-aware Routing protocol(TRP)Based on packet Forwarding Ratio Analysis to detect malicious nodes

Wireless sensor networks (WSNs) are vulnerable to many backdoor attacks counting malicious nodes. Malicious nodes can inject false data, drop packets, or even launch denial-of-service attacks. One way to detect malicious nodes in WSNs is to use trust-based routing protocols. Trust-based routing protocols calculate a trust value for all network nodes. The trust value is based on factors such as the node’s packet forwarding ratio, energy level, and location. In this paper, the proposed Trust-aware Routing Protocol (TRP) model for detecting malicious nodes in WSN using packet forwarding ratio-based. Our protocol uses the Ratio for packet forwarding as the main factor in calculating the trust value of a node. We propose the results based on our experiments: Our protocol can effectively detect malicious nodes with a high accuracy. Our protocol has a lower false positive rate than other trust-based routing protocols. Our protocol is lightweight and can be implemented on resource-constrained sensor nodes. Proposed model work makes a significant contribution to the field of WSN security.The proposed protocol outperformed to detect malicious nodes with an accuracy of 96.791% and the false positive rate was 5.031%. The false negative percentage is 0%, improved the security of WSNs and protected them from malicious nodes.
