Design and analysis of scalable scheduling schemes for high-speed input-queued packet switches
… when using either maximum-weight matching schemes or iterative maximal-weight matching schemes with a significant speedup. These different approaches require either high computation complexity or high memory costs that can make them infeasible. Therefore, there is a need for low-complexity …

Scheduling algorithms for arbitrary communication networks
We consider the problem of designing scheduling schemes for networks with arbitrary topology and scheduling constraints. We address the optimality of scheduling schemes for packet networks in terms of throughput, delay and fairness. Specifically, we design two scheduling schemes. The first one …

Maximizing throughput while maintaining fairness and priority in wireless ad-hoc networks
… Graph or Conflict Matrix' and presented scheduling schemes to address issues like network throughput, fairness and QoS (priority) in a network. We particularly studied the transmission patterns in a network given a specific conflict graph which in turn depends on factors like number of …

Scheduling in multiple processor real-time systems.
… to investigate the effects of different dynamic scheduling heuristic rules on the design of Real-Time Systems (RTS) which allow for the execution of complex responses. Complex responses are characterized by the concurrent nature of activity execution. RTS design will be done through the use of a …

Ensuring Service Level Agreements for Composite Services by Means of Request Scheduling
… problem this thesis focuses on using request scheduling for meeting Service Level Agreements (SLAs). The special focus is given to composite services specified by means of workflow languages. The proposed solution suggests using two level scheduling: global and local. The global policies …
