Définition et validation d'un modèle de communication supportant la communication basée contenus dans les réseaux mobiles ad hoc discontinus

Abstract : Research 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.
