AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The throughput of wireless networks is known to scale poorly when the number of users grows. The rate at which an arbitrary pair of nodes can communicate must decrease to zero as the number of users tends to infinity, under various assumptions. One of them ...
This paper presents the research activities carried out within the scope of the Liaison project. Most of the work has been performed on WiFi location. WiFi is nowadays widely deployed in buildings such as hotels, hospitals, airports, train stations, public ...
The ad hoc networking technology can enable novel civilian and military applications. However, ad hoc networking protocols are vulnerable to a wide range of attacks. The design of defense mechanisms is a challenging problem, especially in comparison to sec ...
We show that network coding allows to realize significant energy savings in a wireless ad-hoc network, when each node of the network is a source that wants to transmit information to all other nodes. Energy efficiency directly affects battery life and thus ...
We consider a cross-layer design of wireless ad-hoc networks. Traditional networking approaches optimize separately each of the three layers: physical layer, medium access and routing. This may lead to largely suboptimal network designs. In this work, we p ...
The low-power communication in wireless sensor networks can be impacted by severe channel impairments. In this paper, to address this problem and achieve high network goodput, we propose that the medium access control protocol takes into consideration the ...
This paper (in Frensh) summarizes recent results obtained by using shot noise processes for two applications in communication networks: first, TCP/IP traffic models for backbone networks; and next the study of connectivity under rate constraints in wireles ...
In this paper we will propose a relaying scheme for wireless multi-hop networks. It is based on collaboration of intermediate relays at network layer to forward useful side information in place of dumbly forwarding packets. In our scheme we assume that the ...
Some forms of ad-hoc networks need to operate in extremely performance- challenged environments where end-to-end connectivity is rare. Such environments can be found for example in very sparse mobile networks where nodes ”meet” only occasionally and are ab ...
Network coding is an area that has emerged in 2000, and has since then attracted an increasing interest, as it promises to have a significant impact in both the theory and practice of networks. To evaluate its performance in realistic situation, we develop ...
