Full textSatellite communication is the achievement of more than 50 years of research in the fields of telecommunications and space technologies.First satellites had exorbitant costs for very limited performances. Technological advances occurred in these areas have helped them to become commercially feasible and satisfying. This enable the increase of satellite launches and thus, building complete satellite networks.Today, there are many GEO or LEO satellite constellations used for civilian or military applications. In general, routing in these constellations is done by pre-computing existing routes. These routes are then used for a given period and refreshed if needed. This type of routing is optimal only on deterministic topologies as a consequence we need to consider other solutions if we relax this assumption. The objective of this thesis is to explore alternatives to pre-computed routing. As a potential solution, we propose to assess the suitability of replication based routing protocols issued from the world of delay tolerant networks, DTN. To provide a relevant framework to study this topic, we focus on a particular constellation that present a quasi-deterministic nature and do not provide direct connectivity between all nodes of the system. In a second part, we focus on the modeling of the Binary Spray and Wait, routing protocol. We develop a model that can theoretically determine the distribution of end-to-end delay for any type of network, homogeneous and heterogeneous. Finally, we present a possible use of this model to conduct more in-depth theoretical analysis

Full textThe Internet has entirely reshaped the way we communicate and interact with one another. The rapid development of the wireless infrastructure by network providers has being accompanied by an exponential growth in the number of mobile users. However, global Internet access and connectivity still face several challenges: scarce or poor quality connectivity in developing countries or places with limited accessibility, physical obstacles limiting the deployment of wireless networks and natural or man-made disasters. Delay tolerant networks (DTNs) were introduced to deal with environments where interruptions or disruptions of service were expected. Such networks usually lack of end-to-end paths or any infrastructure to help communications. In these networks, mobile nodes may interact using their contacts as a communication opportunity. The store-carry-forward paradigm allows nodes to exploit spatio-temporal paths created by contact opportunities in order to deliver messages over time. Instead we raise the question: can we design a mobile and opportunistic infrastructure that could help deliver messages? In the quest to provide such infrastructure, we study the application of temporal random walks (TRW) over the opportunistic networks. We explore the application and impact of TRW as a minimal and non invasive infrastructure from two points of view: data forwarding and data recollection/transmission

Full textResearch activity in the area of mobile ad hoc networks (MANETs) has aimed mainly at defining dynamic routing methods within these networks. Most proposals assume that communication between two mobile devices is possible only if a message delivery route can be established between devices when necessary. This approach is equivalent to considering that communication between two mobile devices can only be achieved in a fully-connected network. More recently, the field has been extended to consider the specificities of disconnected MANETs, that is MANETs appearing as collections of subnets (referred to as islands of connectivity) within which terminals can communicate using dynamic routing, but among which no communication is possible. Routing in such networks is a research area that is gaining attention. The approach generally adopted, called opportunistic networking, is to leverage mobile devices as data mules, able to store, carry, and forward messages among disconnected islands in order to deliver messages to their destinations. In this thesis I am interested in supporting content-based communication in disconnected MANETs. Content-based communication is a communication model in which information flows towards interested terminals rather than towards specifically set destinations. I believe that many applications can benefit from this communication model, such as file sharing, news articles distribution, service advertisement and discovery, etc. In this manuscript I present the communication protocol I have designed to provide this style of communication in disconnected MANETs ; I also present the experiments I conducted to validate my approach. This protocol relies on a combination of content-based communication, opportunistic networking, and multi-hop communication concepts to take into account the characteristics of disconnected mobile ad hoc networks

Full textThroughout this thesis, we seek to propose and design optimized strategies that are adapted to a widespread class of use cases in which communications between network nodes may be disrupted by adverse deployment conditions, assuming that standard fault repair mechanisms are unable to address and mitigate the effects created by these disruptions. Such use cases include the applicative context of emergency communication networks, which are often met in the wake of disasters, or more generally after the occurrence of any unexpected event which may leave the existing networks of an affected area partially or even totally damaged. The aforementioned disruptions can be of different nature: they may result from a detrimental network dimensioning (e.g. low number of network nodes, excessive node scattering surface, insufficient radio communication range, . . . with respect to the other considered deployment parameter values). They may also stem from external causes, e.g. the unexpected presence of obstacles on the area of interest, or the existence of extrinsic interference sources that may disturb the considered network. In general, it can be observed that given such disruptions, a network which is not inherently designed to operate in these conditions is likely to under-perform and, as a result, to offer a significantly decreased quality of experience to its users. In this regard, we seek to compare our perception of the traditional concept of mobility as seen in common infrastructure, ad hoc or disruption- and delay-tolerant wireless networks with the principles of controlled mobility, according to which a network node may directly control its own movement and affect its trajectory accordingly. More precisely, we investigate the means to define a virtual force system which encompasses multiple repulsive, attractive, friction and alignment forces, all of which may be applied to network nodes in order to enforce this principle of controlled mobility.We then explain how virtual forces can concretely be implemented and used in a realistic network deployment, and we specify a protocol solution and its variations, which we enforce within controlled mobility strategies with the prospect that those prove best suited to the considered network environments. We first take as an applicative background a scenario aiming to fight the spread of an invasive species, the Asian hornet, and we outline a practical deployment relying on a wireless ad hoc network formed with unmanned aerial nodes which all enforce our first proposed controlled mobility strategy. We then seek to identify the best value intervals for the key parameters of our virtual force-based protocol, anticipating that configured with these values, the deployed network will yield its best performance in terms of delays and packet delivery. Later, we introduce a scenario related to the deployment of an emergency communication network, still on the basis of wireless ad hoc network principles. We then present an analysis of how a second proposed controlled mobility strategy performs in this applicative environment. In particular, we show how this strategy behaves when the number of network nodes increases. At that point, we address the context of networks deployed in challenging conditions, and of the use of disruption- and delaytolerant mechanisms. We aim here at designing a third type of strategy that jointly uses disruption- and delay-tolerant mechanisms as well as controlled mobility principles, in order to significantly increase the overall network performance. We then investigate and explain how this strategy allows transmitting a fraction of the user traffic with short delays, when an end-to-end route is available along a communication chain, while the other fraction of the traffic is delivered with longer delays, with the support of delay-tolerant routing mechanisms
