OFDMA Resource Allocation in Hybrid Wireless Network

This paper studies OFDMA resource allocation for QoS provision in hybrid wireless network, which includes an infrastructure based cellular network and many ad-hoc nodes. The base station has to consider not only those cellular nodes with direct links but also ad-hoc nodes with multihop connectivity. We formulate the optimization problem to maximize the overall throughput, while satisfying the individual QoS constraints of all cellular and ad-hoc users. We also provide simulation results to illustrate the optimal solutions for different network configurations.
