In this paper, we develop an efficient resource allocation algorithm for multiple-input multiple-output orthogonal frequency division multiple access (MIMO-OFDMA) networks that considers all OFDM symbols in the current frame. By recognizing the special structure of the optimization problem, we develop an efficient algorithm based on graph theory that has a complexity independent of the number of OFDM...
We propose two efficient scheduling algorithms for OFDMA networks based on graph theory. The algorithms overcome many drawbacks of previously proposed algorithms such as assuming a single service scenario, limiting the QoS parameters to instantaneous data rate and considering a single OFDM symbol in each scheduling decision. Also, our algorithms enable the system designer to control the tradeoff between...
