A reverse auction mechanism for hybrid access femtocell networks

Femtocell enable larger network capacity by improving channel state and reducing transmission distance. Hybrid access is an efficient approach to reduce cross-tier inference so as to enhance overall network performance. In this paper, we propose a new reverse auction-based access rate allocation mechanism to maximize the utility of the femtocell access point (FAP) and the user for hybrid femtocell networks. We treat the access rate as a trade commodity. The macro users in dead zone acts as auctioneer (buyer) and femtocell access point act as bidder (seller). Numerical results show that the proposed method can achieve higher system utility in contrast to random selected method.
