Wireless sensor networks (WSNs) is the backbone of the new generation of internet of things (IoT). WSNs are growing rapidly and security threats are increasingly growing as well. Trust computing plays a crucial role in WSN security modeling. In WSN node trust is important to keep the network safe and operational. This paper presents the state-of-the-art techniques in WSN Trust modeling. Comparison and analysis of most recent solutions were conducted. Direction and trends of current and future research approaches are also presented.
