Study of an Iterative Resource Allocation Algorithm for a 2-Hop OFDMA Virtual Cellular Network

Multi-hop networks can increase the data transmission rate in the next generation mobile network. A new resource allocation algorithm is required for this new type of network architecture. A multi-user resource allocation scheme has been proposed for a 2-hop OFDMA virtual cellular network (VCN). Using that scheme, the VCN can provide better channel capacity than the single hop network (SHN) for low transmission power. However, in the interference dominant transmission power region, the SHN performs better than the VCN. This paper proposes some iterative schemes to increase the channel capacity of the VCN. Using computer simulations, this paper shows that applying those iterative schemes can augment the ergodic channel capacity of the VCN in the interference dominant transmission power region.
