Efficient Scheduling for Heterogeneous Services in OFDMA Downlink
We consider optimal allocation of resources to users in a downlink OFDMA system to support heterogeneous applications consisting of both deadline-sensitive (DS) and best-effort (BE...

Design of Fair Weights for Heterogeneous Traffic Scheduling in Multichannel Wireless Networks
Fair weights have been implemented to maintain fairness in recent resource allocation schemes. However, designing fair weights for multiservice wireless networks is not trivial bec...
