“…Asai et al [8] proposed a trust model named TMUMO that prevents gray-hole attacks through the use of nodes utilizing a gateway-independent trust evaluation technique. In this model, the trust value and usage value are derived from the packet forwarding ratio and the amount of usage by the node for the packet relay, respectively.…”

“…This puts a burden on all nodes as they are required to send a control message generated by trust evaluation. Second, the schemes proposed in [6,8,10,11] have a common disadvantage in that every node must inspect all surrounding traffic to perform a trust evaluation. This is not suitable for resource-constrained sensor node environments.…”

“…There are two main types of trust evaluation techniques, which are summarized in the Related Works section: The first type is the gateway-assisted trust evaluation approach, in which the gateway or cluster head with a higher computing power than that of other nodes performs a trust evaluation of all child nodes [5][6][7]. The second one is the gateway-independent trust evaluation approach, in which all nodes perform a trust evaluation of their surrounding nodes [8][9][10][11].…”

In tactical wireless sensor networks, tactical sensors are increasingly expected to be exploited for information collection in battlefields or dangerous areas on behalf of soldiers. The main function of these networks is to use sensors to measure radiation, nuclear, and biochemical values for the safety of allies and also to monitor and carry out reconnaissance of enemies. These tactical sensors require a network traffic flow that sends various types of measured information to the gateway, which needs high reliability. To ensure reliability, it must be able to detect malicious nodes that perform packet-dropping attacks to disrupt the network traffic flow, and energy-constrained sensors require energy-efficient methods to detect them. Therefore, in this paper, we propose a stepwise and hybrid trust evaluation scheme for locating malicious nodes that perform packet-dropping attacks in a tree-based network. Sensors send a query to the gateway by observing the traffic patterns of their child nodes. Moreover, depending on the situation, the gateway detects malicious nodes by choosing between gateway-assisted trust evaluation and gateway-independent trust evaluation. We implemented and evaluated the proposed scheme with the OPNET simulator, and the results showed that a higher packet delivery ratio can be achieved with significantly lower energy consumption.
