Traffic-Oriented Resource Allocation for mmWave Multi-Hop Backhaul Networks

Wenjuan Pu, Xiaohui Li, Jiangwei Yuan, Xu Yang,
This letter investigates traffic-oriented resource allocation for millimeter-wave (mmW) multi-hop backhaul (BH) networks. The problem is formulated to minimize the sum of the distances between the data rate and BH traffic of all the small cell base stations (SBSs) under limited BH resources, considering concurrent transmissions to cater for the huge BH traffic occurred in the aggregated SBSs. The problem is casted as a matching game, since it is a two-sided stable and Pareto optimal matching between sub-channels and SBSs. By analyzing the preference profiles and judge functions of SBSs and sub-channels, respectively, an algorithm based on a matching theory is proposed. Simulations demonstrate that our algorithm can effectively cope with the huge aggregated traffic occurred in the mmW multi-hop BH networks with limited BH resources.
