Architecting space communication networks
Reliable communication and navigation services are critical to robotic and human space missions. NASA currently provides them through three independent and uncoordinated network that consist of both Earth-based and space-based assets, all managed under the Space Navigation and Communication …

The Reticulation of Communication Networks
… explanation of observable instances of communication in organizations and in social collectives more generally. The principal approach to this phenomenon has been the study of communication networks, and this study has generated a considerable body of research. However, the utility of …

Adaptive data acquisition for communication networks
In an increasing number of communication systems, such as sensor networks or local area networks within medical, financial or military institutions, nodes communicate information sources (e.g., video, audio) over multiple hops. Moreover, nodes have, or can acquire, correlated information sources …

Multiaccess and fading in communication networks
Two fundamental issues in the design of wireless communication networks are the interference among multiple users and the time-varying nature of the fading wireless channel. We apply fundamental techniques in information theory and queueing theory to gain insights into the structure of these …

Scheduling algorithms for arbitrary communication networks
… 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 achieves …

Secure Communication Networks for Connected Vehicles
… drive-by-wire and autonomous driving, advanced communication protocols to connect vehicles and the infrastructure have been proposed. However, practical large-scale deployments have been hindered due to caveats such as hardware, and infrastructure demands — including the security of vehicles, …

Asynchronous bi-directional relay-assisted communication networks
… by the two transceivers. Hence, we model such a communication scheme as a frequency selective multipath channel which produces ISI at the two transceivers, when the data rates are relatively high. We study both multi- and single-carrier communication schemes in such networks. In a multi-carrier …

Efficient packet delivery in modern communication networks
Modern communication networks are often designed for diverse applications, such as voice, data and video. Packet-switching is often adapted in today's networks to transmit multiple types of traffic. In packet-switching networks, network performance is directly affected by how the networks handle …

The spatial structure of mobile communication networks
… between the spatial and topological structure of communication networks with the availability of large scale anonymous datasets on the communication and mobility patterns of individuals. These datasets, captured as a by-product of modern communications technology, provide a detailed view of the …

Digital communication networks incorporating mobile data terminals
The use of digital communication systems is increasing very rapidly. This is due to lower system implementation cost compared to analogue transmission and at the same time, the ease with which several types of data sources (data, digitised speech and video, etc.) can be mixed. The emergence of …

Routing in packet switched computer communication networks
… of the routing path in packet-switched computer-communication networks. Computer-communication networks over the past decade are outlined. A glossary of some of the terms used throughout this thesis are introduced. A brief description follows of the advantages of packet switching over the more …

The Design and Analysis of Reliable Communication Networks
In this study, a communication network is represented by a graph, and the problem of designing a network that will operate as reliably as possible is investigated. Failure of the network is associated with the removal of a set of nodes which disconnects the graph or by the removal of a set of edges …

Adaptive control of communication networks using learning automata.
This research investigates communications network routing procedures, based on distributed learning automata concepts for circuit and packet switched networks. For this application, the learning automaton is shown to be an ideal adaptive control mechanism, with simple feedback and updating …
