Recipients' anonymity in multihop ad-hoc networks
No full textMultihop ad-hoc networks have a dynamic topology. Retrieving a route towards a remote peer requires the execution of a recipient lookup, which can publicly reveal sensitive information about him. Within this context, we propose an efficient, practical and scalable solution to guarantee the anonymity of recipients' nodes in ad-hoc networks.Los saltos múltiples de redes ad-hoc tienen una topología dinámica.

Retinal Thickness Changes Over Time in a Murine AD Model APP NL-F/NL-F.
No full textBackground: Alzheimer's disease (AD) may present retinal changes before brain pathology, suggesting the retina as an accessible biomarker of AD. The present work is a diachronic study using spectral domain optical coherence tomography (SD-OCT) to determine the total retinal thickness and retinal nerve fiber layer (RNFL) thickness in an APPNL-F/NL-F mouse model of AD at 6, 9, 12, 15, 17, and 20 months old compared to wild type (WT) animals. Methods: Total retinal thickness and RNFL thickness were determined. The mean total retinal thickness was analyzed following the Early Treatment Diabetic Retinopathy Study sectors. RNFL was measured in six sectors of axonal ring scans around the optic nerve. Results: In the APPNL-F/NL-F group compared to WT animals, the total retinal thickness changes observed were the following: (i) At 6-months-old, a significant thinning in the outer temporal sector was observed; (ii) at 15-months-old a significant thinning in the inner temporal and in the inner and outer inferior retinal sectors was noticed; (iii) at 17-months-old, a significant thickening in the inferior and nasal sectors was found in both inner and outer rings; and (iv) at 20-months-old, a significant thinning in the inner ring of nasal, temporal, and inferior retina and in the outer ring of superior and temporal retina was seen. In RNFL thickness, there was significant thinning in the global analysis and in nasal and inner-temporal sectors at 6 months old. Thinning was also found in the supero-temporal and nasal sectors and global value at 20 months old. Conclusions: In the APPNL-F/NL-F AD model, the retinal thickness showed thinning, possibly produced by neurodegeneration alternating with thickening caused by deposits and neuroinflammation in some areas of the retina. These changes over time are similar to those observed in the human retina and could be a biomarker for AD. The APPNL-F/NL-F AD model may help us better understand the different retinal changes during the progression of AD.This research was funded by the Ophthalmological Network OFTARED (RD16/0008/0005) of the Institute of Health of Carlos III of the Spanish Ministry of Science and Innovation; and the Research Network RETIBRAIN (RED2018-102499-T) and Grant PID2019-106581RB-I00 of the Spanish Ministry of Science and Innovation; and Leducq Foundation for Cardiovascular Research TNE-19CVD01.

Cooperation enforcement in ad-hoc wireless networks
No full textIncludes bibliographical references.Ad-hoc networks consist of a system of wireless nodes that can freely and dynamically self-organise into a working network topology. This allows people to internetwork seamlessly in areas that have no preexisting communication infrastructure. Nodes are expected to forward the traffic of other nodes in order for the packets to reach their final destination. It is envisaged that community ad-hoc networks will become widespread in the near future, as they require no administrative support. Nodes will be able to enter and leave the network as they choose. An unfortunate result is that in an open multi-agent system such as this, the role-players tend to be unreliable and self-interested
Gerência da largura de banda para garantir QoS adaptável em redes sem fio ad hoc
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico.As redes sem fio apresentam um novo paradigma computacional que tem como função principal prover aos usuários o acesso permanente à rede independente de sua localização física. Com a diminuição dos custos dos dispositivos portáteis e o aumento da sua capacidade surgiu um novo conceito chamado redes ad hoc, onde a comunicação é feita diretamente entre os computadores móveis. Neste trabalho são descritas as características fundamentais das redes ad hoc. Assim como as principais tendências para garantir a qualidade de serviço nas redes sem fio, considerando as características: transmissão pouco confiável, largura de banda limitada e alta taxa de erros. No trabalho é proposto um mecanismo para manter QoS adaptável sobre o princípio de gerência da largura de banda em redes sem fio de topologia ad hoc. Também foi desenvolvido um software que permite simular ambientes de redes ad hoc, fazendo as conexões em conformidade com o critério do mecanismo proposto. Para a validação realizaram-se várias experiências que permitiram provar as vantagens do mecanismo. Naquelas redes onde o mecanismo de QoS adaptável foi usado, obteve-se melhor aproveitamento do canal de transmissão, ao mesmo tempo que maior quantidade de conexões eram aceitas

Routing And Communication Path Mapping In VANETS
No full textVehicular ad-hoc network (VANET) has quickly become an important aspect of the intelligent transport system (ITS), which is a combination of information technology, and transport works to improve efficiency and safety through data gathering and dissemination. However, transmitting data over an ad-hoc network comes with several issues such as broadcast storms, hidden terminal problems and unreliability; these greatly reduce the efficiency of the network and hence the purpose for which it was developed. We therefore propose a system of utilising information gathered externally from the node or through the various layers of the network into the access layer of the ETSI communication stack for routing to improve the overall efficiency of data delivery, reduce hidden terminals and increase reliability. We divide route into segments and design a set of metric system to select a controlling node as well as procedure for data transfer. Furthermore we propose a system for faster data delivery based on priority of data and density of nodes from route information while developing a map to show the communication situation of an area. These metrics and algorithms will be simulated in further research using the NS-3 environment to demonstrate the effectiveness
