TCP sur lien asymétrique : analyse des phénomènes et étude de solutions de faible empreinte mémoire ou de bout-en-bout by Tristan Braud( )

1 edition published in 2016 in French and held by 2 WorldCat member libraries worldwide

Using TCP on asymmetric links may lead to unexpected and significant performance drops, severely degrading user experience. Those performance drops can come in various forms, among which a huge latency at the beginning of a connection, under-utilization of link capacities, or even excessive delays for the whole connection.In order to prevent those effects to happen, various approaches exist, either end-to-end through changes in the TCP/IP stack, or in the network core with a collection of scheduling algorithms.The first goal of this thesis is to explore if and how an end-to-end policy (i.e where CPU and memory resources are the most abundant) can achieve similar results as buffering policies in the core of the network. Secondly, we provide an in-depth analysis of the root cause of the performance drops, and evaluate existing algorithms. Finally, new solutions, both end-to-end and in the core of the network, are brought and tested in real life networks
Etude du standard IEEE 802.11 dans le cadre des réseaux ad hoc = tudy of the IEEE 802.11 standard un ad hoc networks context : from simulation to experimentation : de la simulation à l'expérimentation by Dominique Dhoutaut( Book )

2 editions published in 2003 in French and held by 2 WorldCat member libraries worldwide

Les réseaux ad hoc constitués de mobiles ne s'appuient sur aucune infrastructure fixe et s'auto-organisent au gré des mouvements. Dans ce domaine de recherche récent, la majeure partie de l'activité est tournée vers le routage. De part sa disponibilité commerciale et sa facilité d'utilisation, la norme IEEE 802.11(Wi-Fi) est en général choisie comme support dans de nombreux travaux de recherche sur le routage. Mais 802.11 n'a pas été conçue pour le contexte des réseaux multi-sauts et présente des limites que nous nous attachons à mettre en lumière. Par simulation puis par expérimentation réelle, nous soulevons un certain nombre de problèmes, allant de l'équité dans l'accès au canal aux problèmes de portée et d'impact de l'environnement. Grâce à une étude détaillée de ces divers phénomènes, cette thèse a un impact en particulier sur les protocoles de routage ad hoc et la manière dont ils sont élaborés, mais aussi sur d'autres protocoles de niveau supérieur, à commencer par TCP

Radio resources management for Terahertz nanonetworks by Lina Aliouat( Book )

2 editions published in 2020 in English and held by 2 WorldCat member libraries worldwide

Wireless NanoNetwork (WNN) is a wireless ad hoc network composed of a high number of sub-millimetric nodes called nanonodes. The size of the devices makes the Terahertz band (0.1-10 THz) a suitable candidate for supporting the wireless communication between nanonodes.The intrinsic limitations of nanonodes (energy, memory, communication range, and computation capacity) and the severe path loss of Terahertz band communication, impose WNN protocols to be adapted to these stringent requirements and represent a challenge to the communication (much below one meter) among nanonodes and the overall network performance.In this thesis, we studied different options for improving the lower networking layers (access protocols, and routing protocols)for Terahertz WNN. First, we proposed a new Terahertz pulse-based access protocol (SDMA-TSOOK) that allows to balance the radio access over the active nanonodes while reducing the co-channel and collision risks. The SDMA-TSOOK protocol is then compared with the most relevant methods such as : TSOOK, RD-TSOOK and SRH-TSOOK.We proposed three 2.5 networking layer protocols for reducing the density of the nanonetwork physical topology. Indeed, the high concentration of nanonodes increases the number of direct communication links. Therefore, it is important to reduce smartly the number of direct links to reduce the flooding effects and the routing complexity. First, We proposed a protocol to convert the physical topology of the network into directed-graph topology where the direct neighboring nodes of each node is reduced to a subset of its physical neighbors. We also studied cluster-based traffic regulation approach for Terahertz nanonetwork. In this case, the physical topology of the network is reduced to a hierarchical based topology that allows to prevent multiple receptions and loops effects.Finally, We extend our work, to the study of routing protocols in ultra dense nanonetworks. We have shown that classical and dedicated ad hoc nanonetwork routing solutions are inefficient for ultra dense nanonetwork, particularly, when the nanonetwork deployment presents distortions and concave sides. We proposed then a proactive multirelay to multirelay routing protocol that takes into account the residual energy level of the nanonodes and the reliability of the routing paths
Supports de communications ubiquitaires pour les réseaux à l'échelle de la ville by Pierre Brunisholz( )

1 edition published in 2019 in French and held by 2 WorldCat member libraries worldwide

Wi-Fi is everywhere in cities, whether through the growing number of publicaccess points, or the massive private access points deployment, in the formof set-top boxes for the major part.If we assume that all these access points are usable in order to allow anydevice to access the Internet, then we would potentially have network coveragethroughout the city.This assumption led us to wonder if Wi-Fi could be used as a city-wide network.This network could, more specifically, be used in a context of mobility.However, Wi-Fi was not designed to manage mobile users, and devices have tooften change their access points when they no longer have connectivity.This mechanism, called handover, can be long because devices must first detecttheir connectivity losses before they can start looking for the next accesspoint to associate with.It can be particularly long for devices such as smartphones because they areenergy constrained and therefore do not apply an aggressive handover policy.In this context we tried to characterize the possible Wi-FI applications for amoving user, considering the handover duration, the user speed and the accesspoints density in the city.We found that for slow-moving users, the impact of the handover is smallcompared to the their overall connectivity.This allows them to use bandwidth-intensive applications as long as they areto some extend delay-tolerant.However, when the user's speed increases, the impact of handover's durationgradually degrades the user's connectivity, so that high speed users can nolonger expect to use different access points.Fast moving devices spend more time performing handovers with new access pointsthan transmitting application data.Retransmissions play an important role in the duration of handover.In order to study in detail the retransmissions in 802.11, we have set up atestbed allowing us to observe the sequences of retransmitted messages usingdifferent implementations of 802.11 when we suddenly make the access pointdisappear.We compared these sequences with the one described in the standard, and we wefound that the maximum number of retransmissions as well as the growth in thecontention window were not respected.In addition, these implementations spend a lot of time trying to retransmitbefore initiating their handover procedures.Retransmissions are also used in the rate control algorithms to determine ifthe link is deteriorating.However, during contention, the number of losses increases with the higherprobability of collisions.In order to observe the impact of retransmissions on the rate controlalgorithms during contention, we have set up a testbed composed of about thirtyidentical stations.We found that the rate control algorithm used underperforms compared to theuse of a single modulation.Finally, we proposed a geographical addressing scheme compliant with theInternet infrastructure.It allows to obtain both a hierarchical division of the world, and ahierarchical prefix for the addresses, similar to the one used in the CIDRformat.We show that this addressing scheme can be used in multicast addresses to sendmessages to specific geographical areas (minimum area of one square meter)
