Routing in the Space Internet: A contact graph routing tutorial
(Academic Press Ltd - Elsevier Science Ltd, 2021-01-15)
A Space Internet is possible, as long as the delay and disruption challenges imposed by the space environment are properly tackled. Because these conditions are not well addressed by terrestrial Internet, more capable ...
Assessing contact graph routing performance and reliability in distributed satellite constellations
(Hindawi Limited, 2017-07)
Existing Internet protocols assume persistent end-to-end connectivity, which cannot be guaranteed in disruptive and high-latency space environments. To operate over these challenging networks, a store-carry-and-forward ...
On route table computation strategies in Delay-Tolerant Satellite Networks
(Elsevier Science, 2018-11)
Delay-Tolerant Networking (DTN) has been proposed for satellite networks with no expectation of continuous or instantaneous end-to-end connectivity, which are known as Delay-Tolerant Satellite Networks (DTSNs). Path ...
Analysis of communication strategies for earth observation satellite constellations
(Institute of Electrical and Electronics Engineers, 2016-06)
Earth observation satellite constellations are arising as a new paradigm with important advantages in comparison with traditional monolithic systems. In particular, the concept of Segmented Architecture proposes to transform ...
Congestion management techniques for disruption-tolerant satellite networks
(John Wiley & Sons Ltd, 2018-03-23)
Delay and disruption-tolerant networks are becoming an appealing solution for extending Internet boundaries toward challenged environments where end-to-end connectivity cannot be guaranteed. In particular, satellite networks ...
Routing-aware fair contact plan design for predictable delay tolerant networks
(Elsevier Science, 2014-06)
Delay tolerant networks (DTNs) have become a promising solution for extending Internet boundaries to challenged environments such as satellite constellations. In this context, strategies to exploit scarce communication ...
Routing in Delay-Tolerant Networks under uncertain contact plans
(Elsevier Science, 2021-12)
Delay-Tolerant Networks (DTN) enable store-carry-and-forward data transmission in networks challenged by frequent disruptions and high latency. Existing classification distinguishes between scheduled and probabilistic DTNs, ...
On the Design and Analysis of Fair Contact Plans in Predictable Delay-Tolerant Networks
(Institute of Electrical and Electronics Engineers, 2014-11)
Delay-tolerant networks (DTNs) have become a promising architecture for wireless sensor systems in challenged communication environments where traditional solutions based on persistent connectivity either fail or show ...
Analysis of the value added from improving contact-center response time in a customer service application
(Universidad de los AndesMaestría en Ingeniería IndustrialFacultad de IngenieríaDepartamento de Ingeniería Industrial, 2022-05-27)
Targeted maximum likelihood estimation (TMLE) procedure is proposed to evaluate the causal impact of the waiting time and abandonment of a phone call in customer profits. Based on different spending behaviors and Customer ...
Síntese e caracterização de scaffolds de Pcl/Biovidro: estudo in vitro da biocompatibilidade e da diferenciação celular
(Universidade Estadual Paulista (Unesp), 2018-12-14)
As membranas reabsorvíveis tem sido utilizadas para promover o crescimento ósseo em defeitos causados por doenças periodontais, periapicais ou por exodontia. Essas membranas possuem diversas composições, podendo ter em sua ...
