Geographical proximity based target-group formation algorithm for D2D advertisement dissemination

We here propose geographical proximity based target-group formation algorithm to efficiently distribute advertisement messages of social-commerce services with device-to-device (D2D) communications. The convergence of D2D communications and the social-commerce services is able to invoke synergistic effects because the D2D users can voluntarily relay the messages to their neighbor users to obtain a great deal of discounts for the corresponding products. By using both the angular distances among target-areas and the physical distances between the D2D access point and the target-areas, we make target-groups for efficient D2D advertisement dissemination. Through intensive simulations, we evaluate the performances of our algorithm with respect to the total number of successfully received users, the average number of relay users, and transmission efficiency compared with the conventional algorithm with cell sectorization based target-group formation.
