The principle of load balancing is examined for dynamic resource allocation subject to certain constraints The emphasis is on the performance of simple allocation strategies which can be implemented on line Either nite capacity constraints on resources or migration of load can be incorporated into the setup The load balancing problem is formulated as a stochastic optimal control problem Variant...

This contribution concentrates on dynamic routing in WDM (Wavelength Division Multiplexing) networks. It is shown that a strategy based on precalculated alternatives and an adaptive dynamic path search performs very well over a wide load range. Moreover, specific effects for the impact of resource allocation strategies in photonic WDM networks are highlighted, especially the influence of wavele...

To my wife Yan, and my parents, for their love, support and encouragement iii ACKNOWLEDGEMENTS My first, and most earnest, acknowledgment must go to my advisor Dr. Mostafa Ammar, who led me into the exciting area of networking and telecommunications. His insights, experience, encouragement, and uncompromising emphasis on quality research guided me through my entire program of study. Much of thi...

This paper is principally concerned with resource allocation for connections tolerating statistical quality of service (QoS) guarantees in a public wide-area ATM network. Our aim is to sketch a framework, based on eeective bandwidths, for call admission schemes that are sensitive to individual QoS requirements and account for statistical multiplexing. We begin by describing recent results appro...

We address the issue of reserving resources at packet switches along the path of connections requiring a deterministic end-to-end delay bound. The switches are assumed to schedule outgoing packets using either the Packet-by-Packet Generalized Processor Sharing (PGPS) or the Rate-Controlled Earliest-Deadline First (RC-EDF) scheduling disciplines. We propose a set of resource reservation policies...

We consider joint optimization of data routing and resource allocation in multicast multihop wireless networks where interference between links is taken into account. The use of network coding in such scenarios leads to a nonconvex optimization problem. By applying the probability collectives (PCs) technique the original problem is turned into a new problem which is convex over probability dist...

Background In order to meet the challenges presented by increasing demand and scarcity of resources, healthcare organizations are faced with difficult decisions related to resource allocation. Tools to facilitate evaluation and improvement of these processes could enable greater transparency and more optimal distribution of resources.   Methods The Resource Allocation Performance Assessment Too...

In today s Internet there exist several repositories of resource allocation information Speci cally these registries contain information about IP address space delegations name space allocations and inter ISP routing policies Such registries are useful for coordinating allocation of Internet names and addresses and for debugging network routing For performance and availability reasons there is ...

OF THE DISSERTATION Resource Allocation in Wireless Ad hoc Networks by Kostas Choumas Doctor of Philosophy, Post Graduate Program in Electrical and Computer Engineering, University of Thessaly, Greece. September 2015 Although most of the daily scenarios of using wireless networking are clearly based on a type of infrastructure, such as an access point or a base station, there is a lot of intere...
