Delay-aware proportional-fair scheduling in OFDMA networks

This project considers the problem of delay-constrained scheduling over wireless fading channels in OFDMA networks like LTE-Advanced networks. Existing scheduling algorithms are considered and extended to OFDMA networks, and performance is evaluated. Specifically, the problem of scheduling users on the downlink in TD-LTE networks has been addressed, and suitably modified proportional-fair and opportunistic schedulers are proposed. Their performance is evaluated in the context of downlink in TD-LTE systems, and compared. Further, a simulation environment has been created which can be used for further analysis of scheduling algorithms in TD-LTE networks, and which can be suitably extended for simulating relay-assisted networks.
