Distributed Algorithms for Resource Allocation in Multi-Hop Random Access Wireless Networks
… scheme for slotted-time protocols that provides proportional fairness with respect to flow-throughput under constraints on the buffer overflow probabilities at each node. We model the end-to-end flows in an ad hoc wireless network using a tandem of finite-size, discrete-time queues, located at …

Fairness and optimality in trading
… approach to address the issues of efficiency and fairness when multiple portfolios are rebalanced simultaneously. A fund manager who rebalances multiple portfolios needs to not only optimize the total efficiency, i.e., maximize net risk-adjusted return, but also guarantee that trading costs are …

Design of Multi-layer Telecommunication Networks: Fairness, Resilience, and Load Balancing
… demands are combined, and investigate different fairness principles, with special attention devoted to proportional fairness. The models are developed for designing the networks for the normal state of network operation, as well as for failure states. For the two-layer problems it is not at all …

COPS: A Framework for Consumer Oriented Proportional-share Scheduling
… Such priority-based mechanisms cannot guarantee proportional fairness for every process. Proportional share schedulers maintain fairness among tasks based on given weight values. In both of these scheduler types, the scheduling decision is done per-process. However, system usage policies are …

Resource Allocation with Carrier Aggregation for Spectrum Sharing in Cellular Networks
… traffic in cellular networks. We use utility proportional fairness allocation policy, where the fairness among users is in utility percentage of the application running on the user equipment (UE). A resource allocation (RA) with CA is proposed to allocate single or multiple carriers resources …

Joint buffer management and scheduling for input queued switches
… In this dissertation, the Queue Length Proportional (QLP) algorithm is proposed for IQ switches. QLP considers both the buffer management and the scheduling mechanism to obtain the optimal allocation region for both bandwidth and buffer space according to real traffic load. In addition, …

Resource allocation and scheduling for communication satellites with advanced transmission antennas
… achieve a substantial power gain and reasonable proportional fairness. We show that a modest number of active parallel beams are sufficient to cover many cells efficiently with dynamic capacity allocation.

Fairness in Communication and Computer Network Design
… bandwidth assignment among them. Obtaining fairness between network users and at the same time assuring efficient network utilization, is a source of non-trivial network optimization problems. Complicating factors are that each user has limited access to the (limited) network resources and …

Facets of proportionality
In this thesis, we study proportional representation in three different collective decision-making settings: voting, budgeting, and clustering. In these settings, we develop new axioms and rules to assess and enable outcomes which proportionally reflect the opinions of all agents taking part in the …

Group scheduling for public safety communications in cellular networks
… needed. QOS requirements such as throughput and fairness are the key requirements of cellular networks. They provide a rich set of applications and social networking capabilities. But most of these features are not available to public safety organizations. These organizations need protected …

Public transit planning with consideration to equity: A Utility Modelling Approach
… novel utility-based mathematical approaches: i) proportional fairness and ii) alpha-fairness, which integrate all (a) to (c) aspects of equity (listed in the previous paragraph) and users’ perspectives of frequency. The numerical analysis addresses several variations of the fair allocation …

A tractable optimization framework for Air Traffic Flow Management addressing fairness, collaboration and stochasticity
… thesis addresses two issues in ATFM research: a) fairness and collaboration amongst airlines; and b) uncertainty inherent in capacity forecasts. A unifying attraction of the overall dissertation is that the Collaborative Decision-Making (CDM) paradigm, which is the current philosophy governing the …

Resource Allocation and End-to-End Quality of Service for Cellular Communications Systems in Congested and Contested Environments
… The radio resource allocation is cast under a proportional fairness formulation which translates to a convex optimization problem. Moreover, the resource allocation scheme considers subscription-based and traffic differentiation in order to meet the QoS requirements of the applications running …

Optimization of Spectrum Allocation in Cognitive Radio and Dynamic Spectrum Access Networks
… maximum network throughput (MNT), max-min fairness (MMF), and proportional fairness (PF). Given different optimization objectives, we developed mathematical models in terms of linear programing and non-linear programing formulations, under the centralized architecture. We also designed a …

Inter-cell interference coordination in 5G ultra-dense networks
… with Energy Efficiency (EE) analysis. Firstly, a proportional fairness scheduler is used to perform resource allocation and maintain fairness among users based on their channel condition. Secondly, an optimization problem to maximize the EE weighted-sum under joint power and bandwidth allocation …

Structure-utilized, Adaptive, and Efficient ML-based Proportional-Fair Scheduling in MIMO Networks for Non-stationary Channels
Proportional Fair (PF) scheduling is widely used in multi-user MIMO systems to balance throughput and fairness. However, PF scheduling is an NP-hard problem, and hence, practical deployments approximate the optimal solution for lower latency at the cost of sub-optimal performance. More recently, …
