The Optimal MAC Layer for Low-Power UWB is Non-Coordinated

Jean-Yves Le Boudec, Alaeddine El Fawal, Ruben Merz, Jörg Widmer

We consider the design of the MAC layer for low power, low data-rate, impulse-radio ultra-wide band (IR-UWB) networks. In such networks, the primary concern is energy consumption rather than rate efficiency. We explore several dimensions such as power cont ...

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 ...

We develop three functions around the MAC layer: (1) Pseudo broadcast is a technique used to improve throughput of broadcast transmissions in case of congested networks. The mechanism consists in sending a packet in unicast to a station using RTS/CTS. Othe ...

IEEE 802.11 works properly only if the stations respect the MAC protocol. We show in this paper that a greedy user can substantially increase his share of bandwidth, at the expense of the other users, by slightly modifying the driver of his network adapter ...

Self-Limiting Epidemic Forwarding

Jean-Yves Le Boudec, Alaeddine El Fawal

We define a self-limiting epidemic service as a dissemination service for ad-hoc environments that is broadcast in nature, but is limited to a local scope around each source. Example applications are chatting or bulletin boards in a traffic jam, in an inst ...

We propose a novel detection method for non-coherent synchronization (signal acquisition) in multi-access UWB impulse radio (IR) networks. It is designed to solve the IUI (Inter-User Interference) that occurs in some ad-hoc networks where concurrent transm ...

A Power Independent detection Method for Ultra Wide Band (UWB) Impulse Radio Networks

Jean-Yves Le Boudec, Alaeddine El Fawal

We propose a novel detection method for non-coherent synchronization in multi-access UWB impulse radio (IR) networks. It is designed to solve the IUI (Inter-User Interference) in particular the Near-Far scenario in the presence of concurrent UWB IR transmi ...

Tradeoff Analysis of PHY aware MAC in Low-Rate,Low-Power UWB networks

Jean-Yves Le Boudec, Alaeddine El Fawal, Ruben Merz, Jörg Widmer

We are interested in the design of physical layer (PHY) aware MAC for self-organized, low power, low data rate impulse-radio ultra-wideband (IR-UWB) networks. In such networks, energy consumption is much more of a concern than the achieved data rates. So f ...

Tradeoff Analysis of PHY-aware MAC in Low-Rate, Low-Power UWB networks

Jean-Yves Le Boudec, Alaeddine El Fawal, Ruben Merz, Jörg Widmer

We are interested in the design of physical-layer aware medium access control (PHY-aware MAC) for self-organized, low power, low data-rate impulse-radio ultra-wideband (IR-UWB) networks. In such networks, energy consumption is much more of a concern than a ...

Synchronizing Method for Impulse Radio Network

Jean-Yves Le Boudec, Alaeddine El Fawal

In IR (Impulse Radio) network, the conventional synchronization (also called signal acquisition) method becomes inefficient and results in a certain failure of synchronization when concurrent transmissions are allowed without controlling their powers. The ...
