This paper studies the joint OFDMA resource allocation and QoS routing problem in a hybrid wireless network, which includes an OFDMA based cellular network and an ad-hoc network with many sensor nodes. In such application, each sensor node generates certain amount of data that need to be sent to cellular base station (BS). The cellular nodes act as gateway to forward all the uplink traffic. We formulate...
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...
