In this paper an OFDMA-based wireless ad hoc network is considered. In addition to the potential of being a source and/or a destination, each node is assumed to be capable of decoding and forwarding its received packets to other nodes in the network. The goal is to determine the optimal data routes, subchannel schedules, and power allocations that maximize a weighted sum rate of the data communicated over the network. Two instances of this problem are considered. In the first instance, each subchannel is exclusively used on one of the links, whereas in the second instance subchannels are allowed to be time shared by multiple links.
