Scheduling in a Multi-Sector Wireless Cell
(University of Waterloo, 2009-10-29)In this thesis, we propose a scheduling problem for the downlink of a single cell system with multiple sectors. We formulate an optimization problem based on a generalized round robin scheme that aims at minimizing the ... -
Scheduling in Large Scale MIMO Downlink Systems
(University of Waterloo, 2008-04-16)This dissertation deals with the problem of scheduling in wireless MIMO (Multiple-Input Multiple-Output) downlink systems. The focus is on the large-scale systems when the number of subscribers is large. In part one, ... -
Scheduling in omnidirectional relay wireless networks
(University of Waterloo, 2013-09-25)The capacity of multiuser wireless network, unclear for many years, has always been a hot research topic. Many different operation schemes and coding techniques have been proposed to enlarge the achievable rate region. And ... -
Scheduling of Overload-Tolerant Computation and Multi-Mode Communication in Real-Time Systems
(University of Waterloo, 2014-12-10)Real-time tasks require sufficient resources to meet deadline constraints. A component should provision sufficient resources for its workloads consisting of tasks to meet their deadlines. Supply and demand bound functions ... -
Scheduling Schemes using Connective Stability
(University of Waterloo, 2012-08-21)Large systems are often constructed using small subsystems which are connected. These interconnections can lead to complex behavior; for example, the entire system may become unstable even if each of the individual subsystems ... -
Scratchpad Memory Management For Multicore Real-Time Embedded Systems
(University of Waterloo, 2018-08-10)Multicore systems will continue to spread in the domain of real-time embedded systems due to the increasing need for high-performance applications. This research discusses some of the challenges associated with employing ... -
Secrecy Resilience of Authorization Policies and Its Application to Role Mining
(University of Waterloo, 2021-09-21)We propose and study a new property that we call secrecy resilience in the context of authorization policies that are used to secure information systems. An authorization policy expresses whether a principal (e.g., a user ... -
Secure and Privacy-Preserving Vehicular Communications
(University of Waterloo, 2008-05-13)Road safety has been drawing increasing attention in the public, and has been subject to extensive efforts from both industry and academia in mitigating the impact of traffic accidents. Recent advances in wireless technology ... -
