Abstract: A trustworthy QoS routing algorithm was proposed. The interval was used to describe the user requirement in order to adapt to the fuzziness of the user QoS and trust demand. Based on the sliding window and windowsill, the trust evaluation and control mechanism were implemented. The satisfaction degree function was introduced to find the optimal path which satisfies the user requirement on the basis of the hunting search algorithm. The simulation of the proposed algorithm was realized, and the performance evaluation was done over several actual and virtual network topologies. The results showed that the proposed algorithm was both feasible and effective, and had better performance than that of the existing ones.
