NDTRA-MAT: A Novel Technique for Evaluating the Data Transfer Rate, Reducing the False Alarm Rate, and avoiding Packet Droppings Rate against Malicious Activity in Wireless Sensor Networks

– Wireless Sensor Networks (WSN) are under attack from insider packet drops. Each node will employ a trust mechanism to assess the trustworthiness of its neighbor nodes to send packets to only the trustworthy neighbors to distinguish packets dropped by inside intruders from network faults. The false alert arises when a normal node's trust value decreases and is removed from the routing paths using trust-aware routing algorithms. Optimizing the packet delivery ratio is a critical design consideration for WSNs. WSNs have long benefited from a secure zone-based routing mechanism already in place. A new routing criterion was developed for packet transfer in multi-hop communication. The routing metric was designed to protect against message manipulation, dropping, and flooding assaults. The method used an alternative way to route a packet while avoiding dangerous zones safely and efficiently in the routing process. Despite energy conservation and greater attack resilience, congestion in the WSN has increased, and the packet delivery ratio has been reduced. Each node has computing power that serves as a transceiver for the network. A packet-dropping node is hacked and forwards any or all the packets it receives. All or some boxes are packages modified by a hacked node that is intended to deliver them. In multi-hop sensor networks, packet dropping and alteration are two popular methods that an adversary can use to interrupt communication. The proposed model NDTRA-MAT is used to avoid packet loss with reduced false alarms. It is compared with the existing models, and the performance is calculated in terms of Malicious Node Detection Accuracy Levels
