Abstract
In view of that the existing auction mechanism cannot effectively allocate cloudlet resource, which leads to a low resource utilization rate and social welfare. In this paper, we design a truthful greedy mechanism (TGM) to coordinate the auction of mobile users (buyers) and cloudlets (sellers). TGM consists of the greedy allocation algorithm based on buyer preferences and pricing mechanism, and improves the usage rate of cloudlets and social welfare. TGM holds computational efficiency, individual rationality, budget balance, and truthfulness. In addition, the simulation result that TGM compared with the existing mechanism has effectively improved in the two aspects of the usage rate of cloudlets and social welfare.
