In the real-time multimedia applications, packet delay should meet stringent Quality of Service (QoS) requirements. Delay Earliest Due Date (EDD) scheduler, originally designed for wireline data networks to operate under a maximum allowed delay, cannot be directly applied to wireless networks, due to the location-dependent errors and time-varying channel conditions. Several modifications of EDD scheduler have been proposed for wireless applications, which typically assume successful admission control, a condition hard to satisfy with wireless networks. In this paper, we propose a removal algorithm for downlink scheduler designed to perform under overloaded situations. Simulation results show that our proposed algorithm outperforms the conventional ones in the QoS guaranteed flows.
