Strategy-Proof Beam-Aware Multicast Resource Allocation Mechanism

Wireless multicast is a rising technology for delivering data from one base station (BS) to multiple mobile stations (MSs) using resource sharing to increase system efficiency. Beam forming is a feature of the 5G base station commonly used in wireless multicast to increase system throughput. However, when we take both beamforming and multicast into account, allocating the resources becomes a considerable problem. In this paper, we propose a beam-aware multicast resource allocation mechanism based on bid transformation and a modified Vickrey-Clarke-Groves (VCG) auction. Our analysis shows that the mechanism is strategy-proof, individually rational, (weak) budget-balanced, and maximizes social welfare. Moreover, the proposed mechanism runs in polynomial time.
