This paper considers the problem of designing scheduling algorithms for multi-channel (e.g., OFDM) wireless downlink networks with n users/OFDM sub-channels. For this system, while the classical MaxWeight algorithm is known to be throughput-optimal, its buffer-overflow performance is very poor (formally, we show it has zero rate function in our setting). To address this, we propose a class of algorithms...
In this paper a new model for a distributed Web service system is presented. The proposed system is composed of multiple Web service components having multiple alternative versions distributed among multiple servers. For a given set of requests an allocation is to be found that maximizes total client satisfaction subject to the resource constraints of the servers. To solve this multidimensional multi...
We present group round-robin (GRR) scheduling, a hybrid fair packet scheduling framework based on a grouping strategy that narrows down the traditional trade-off between fairness and computational complexity. GRR combines its grouping strategy with a specialized round-robin scheduling algorithm that utilizes the properties of GRR groups to schedule flows within groups in a manner that provides O(1)...
