Since existing call admission control (CAC) algorithms designed for heterogeneous wireless networks have failed to consider different characteristics of mobile users and the network load sufficiently, a CAC algorithm based on triangle module operator is proposed. First, proper utility functions are formed with consideration of user satisfaction and mobility as well as the network performance, and then fused by the use of triangle module operator to select the candidate network with the highest trustworthy as the optimal access network. Simulation results demonstrate that the proposed CAC scheme can benefit both users and networks by handling the uncertainty and time-varying information appropriately on finally fuzzy decision.
