Supported by Internet of Things (IoT) devices, trust and security challenges arise, due to the absence of central oversight and the risk of uncooperative participant behaviour. A comparative analysis of existing trust management models and schemes is conducted in this study comparing how they are designed to encourage cooperation and ensure reliable interactions in decentralized energy markets. Emphasis is placed on how these models integrate security mechanisms to build trust and on their computational efficiency for IoT constrained environments. The analysis highlights the trade offs between trust management and IoT device performance, identifying limitations in scalability and latency as participation scales. Results indicate that while several models effectively build trust and promote cooperation, many impose significant resource demands, underscoring the need for balance between trust assurance and operational efficiency. This work provides a comprehensive evaluation of trust mechanisms in transactive energy systems and offers insights into their practical viability in resource-constrained, decentralized environments.FulltextenEnergy tradingInternet of ThingsIoTTrust-modelPeer-to-peerP2PConference PresentationN/A
