Link Association for Small Cell Networks with Wireless Backhaul

Abstract

In this paper, we investigate the optimization problem of association for access and backhaul links with the consideration of multi-hop backhauling. Since the association problem is formulated as a integer programming, we adopt the Lagrangian duality approach to configure the backhaul and access links. Simulation results demonstrate that the proposed algorithm achieves better performance than single-hop backhauling based network and enhances the capacity and coverage by configuring the multi-hop backhauling.
