Abstract Advancements in smart-network technologies enabled the Internet of Things to expand globally. IoT-based Wireless sensor networks play an essential role in collecting and aggregating data in applications like military and health care, where security and power efficiency are significant challenges. Due to vulnerable attacks on several nodes or devices, IoT-based WSN becomes an uncertain environment. This paper aims to offer a fault tolerant, robust, and secure packet forwarding scheme that incorporates more intelligent features and powerful algorithms to eliminate DoS attacks. Initially, routing is performed, with the optimal path determined by recovering malicious nodes detected in an IOT-based WSN environment using the proposed algorithm ICARS- Intelligent Channel aware Reputation scheme based on generation of Resolver Node and Intelligent Route Request and Route Response methods. Next to that, encryption is used to ensure safe transmission. This paper proposes a Modified Rijndael Algorithm (MRA) for secured authentication. By integrating ICARS with MRA, this proposed strategy removes the attacking situation and makes the system more resistant to DoS attacks. The result section proved that the proposed approach increases the throughput, decreases the retransmission ratio, increases energy efficiency, decreases end-to-end delay, and increases Packet Delivery Ratio.
