Revealed preference data from WiFi traces for pedestrian activity scheduling

Michel Bierlaire, Bilal Farooq, Antonin Danalet

We use communication network infrastructure, in particular WiFi traces, to detect activity-episodes sequences in a pedestrian facility. Due to the poor quality of WiFi localization, a probabilistic method is proposed that infers activity-episodes locations ...

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 ...

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 ...

Simple Relaying Strategies for Half-duplex Networks

Christina Fragouli, Ayfer Özgür Aydin, Siddhartha Brahma

We consider the diamond network where a source communicates with the destination through N non-interfering half-duplex relays. Using simple outer bounds on the capacity of the network, we show that simple relaying strategies having exactly two states and a ...

Simple schedules for half-duplex networks

Christina Fragouli, Siddhartha Brahma

We consider the diamond network where a source communicates with the destination through N non-interfering half-duplex relays. Deriving a simple approximation to the capacity of the network, we show that simple schedules having exactly two states and avoid ...

Wireless network simplification: the Gaussian N-relay diamond network

Christina Fragouli, Ayfer Özgür Aydin

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

Understanding and Tackling the Root Causes of Instability in Wireless Mesh Networks

Patrick Thiran, Adel Aziz, David Starobinski

We investigate, both theoretically and experimentally, the stability of CSMA-based wireless mesh networks, where a network is said to be stable if and only if the queue of each relay node remains (almost surely) finite. We identify two key factors that imp ...

Energy Efficient Offloading of 3G Networks

Jean-Yves Le Boudec, Nikodin Ristanovic

A huge increase in the amount of data consumed by smartphone users is becoming a serious problem for mobile operators. In three years, mobile data traffic in the AT&T's network rose 5000%. The US operators invest 50 billion dollars in their data networks e ...

Models of 802.11 Multi-Hop Networks: Theoretical Insights and Experimental Validation

Patrick Thiran, Olivier Dousse, Adel Aziz, Mathilde Durvy

Wireless Multi-Hop CSMA/CA Networks are challenging to analyze. On the one hand, their dynamics are complex and rather subtle effects may severely affect their performance. Yet, understanding these effects is critical to operate upper layer protocols, such ...
