Popis: The need for reliable transmission of data packets is becoming more critical as Wireless Sensor Networks (WSN) gain popularity. Reliable delivery of data packets is possible only when the protocols for routing the data packets are secure and efficient. Due to the constrained nature of the WSN, the current cryptosystems may not be used to provide WSN security. The trust-based intelligent routing, however, may provide security with fewer resources, and it has become common in the last five years. In this paper, a new Trust-Based Secure Intelligent Opportunistic Routing Protocol(TBSIOP) has been proposed. The proposed protocol uses three distinct WSN attributes to compute a node's likelihood of being malicious(Pm). These attributes are sincerity in forwarding data packets(Fs), sincerity in acknowledgment (ACKs), and Energy Depletion (Ed), and these attributes are used for trust computation. Based on the trust factor computed, the relay selection algorithm of the proposed protocol prevents malicious nodes from being chosen as relay nodes. The proposed protocol is applied on the forwarder node list that is formed by Intelligent Opportunistic Routing Protocol. The proposed protocol is simulated and compared with the existing trust-based routing protocols present in the literature. The proposed TBSIOP has better performance in terms of Average Risk Level, Packet Delivery Ratio, End-to-End delay, Energy Consumption, and Network Lifetime than the comparative protocols present in the literature.
