Wireless Sensors Networks (WSNs) are susceptible to many security threats, and because of communication, computation and delay constraints, traditional security mechanisms cannot be used. When trust system is established, the route from source node to destination node should consider nodes' trust on the road but not only QoS. In this paper, we propose a routing model in trust WSNs with respect to both trust and delay. Comparing with ECCR, our model is more accurate in data and reliable in transmission.
