Maximum Throughput Gain of Compute-and-Forward for Multiple Unicast

Michael Christoph Gastpar, Jasper Goseling

Compute-and-Forward (CF), also known as reliable physical layer network coding, is a technique that provides the possibility of exploiting the features of broadcast and superposition in wireless networks. It has been shown that the throughput for multiple ...

Topology Optimization For Energy-Efficient Communications In Consensus Wireless Networks

Martin Vetterli, Benjamin Bejar Haro

Over the past years there has been an increasing interest in developing distributed computation methods over wireless networks. A new communication paradigm has emerged where distributed algorithms such as consensus have played a key role in the developmen ...

We consider the Gaussian N-relay diamond network, where a source wants to communicate to destination node through a layer of N-relay nodes. We investigate the following question: what fraction of the capacity can we maintain using only k out of the N avail ...

Power-line communications are becoming a key component in home networking. The dominant MAC protocol for high data-rate power-line communications, IEEE 1901, employs a CSMA/CA mechanism similar to the backoff process of 802.11. Existing performance evaluat ...

Analyzing and Boosting the Performance of Power-Line Communication Networks

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou

Power-line communications are employed in home networking to provide easy and high-throughput connectivity. IEEE 1901, the MAC protocol for power-line networks, employs a CSMA/CA protocol similar to that of 802.11, but is substantially more complex, which ...

Implementation of a Wireless Mesh Network of Ultra Light MAVs with Dynamic Routing

Dario Floreano, Bixio Rimoldi, Jean-Christophe Zufferey, Alberto Jimenez Pacheco, Yannick Gasser

This paper describes the implementation and characterisation of a mobile ad-hoc network (MANET) of ultra-light intelligent flying robots. The flying nature of the network makes it suitable to collect or disseminate content in urban areas or challenging ter ...

Content Management in Mobile Wireless Networks

Francisco De Meneses Neves Ramos Dos Santos

Approximately one billion users have access to mobile broadband, through which they intend to obtain the same data they can reach using a wired connection. Because of the cost of transmitting data over a mobile-broadband connection and given that 3G networ ...

Bringing Stability to Wireless Mesh Networks

Adel Aziz

Wireless mesh networks were designed as a mean to rapidly deliver large-scale communication capabilities without the support of any prior infrastructure. Among the different properties of mesh networks, the self-organizing feature is particularly interesti ...
