Reducing the effect of network delay on tightly-coupled interaction
… groupware. The main cause of this difficulty is network delay – even amounts as small as 100ms – that disrupts people’s ability to synchronize their actions with another person. To reduce the effects of delay on tightly-coupled interaction, I introduce a new technique called Feedback-Feedthrough …

A Calculus for Network Delay and a Note on Topologies of Interconnection Networks
… we develop a calculus for obtaining bounds on delay in a buffered communication network that applies to a wide variety of models for network operation. The theory we develop is different from traditional approaches to analyzing delay because the model we use to describe the entry of data into …

Design of the Networked Predictive Control Method for Wired and Wireless Networked Systems
The closed-loop control of processes over networks has in recent years become an increasingly popular research topic. This is a very viable solution for a wide variety of applications due to the rapid developments in communication network technologies and the widespread expansion of network devices …

Characterization and prediction of air traffic delays
This thesis presents a new model for predicting delays in the National Airspace System (NAS). The proposed model uses Random Forest (RF) algorithms, considering both temporal and network delay states as explanatory variables. In addition to local delay variables that describe the arrival or …

Virtual reality simulation modeling for tele-surgery and tele-haptic class of applications
… The main causes of such discrepancies are network delay, a lack of view of individual participants' activities, and haptic feedback . Although some strategies exist for dealing with these concerns, they do not adequately address reality, causality, or the sense of co-presence in CVEs during …

Analysis of networks with dynamic topologies
Dynamic hierarchical networks represent an architectural strategy for employing adaptive behavior in applications sensitive to highly variable external demands or uncertain internal conditions. The characteristics of such architectures are described, and the significance of adaptive capability is …

Using the Macroscopic Fundamental Diagram to Characterize the Traffic Flow in Urban Network
… shows that a number of MFDs exist in an urban network. The number of MFDs basically indicate the existence of different levels of service on different network routes. It also demonstrate that the modification of control strategy can optimize the signal timing plan for the links with high …

Time keeping in myriad networks : theories, solutions and applications
Distributed sensor networks make extensive use of a common time reference. In this work we address the problem of time dissemination in a packet switched network when the nodes are NOT generally all connected to an accurate, external time reference source. We thoroughly analyze Network Time …
