A Tutorial-Cum-Survey on Percolation Theory With Applications in Large-Scale Wireless Networks

Ainur Zhaikhan

Connectivity is an important key performance indicator and a focal point of research in large-scale wireless networks. Due to path-loss attenuation of electromagnetic waves, direct wireless connectivity is limited to proximate devices. Nevertheless, connec ...

Throughput Analysis of Large Networks

Serj Haddad

While wired infrastructure constitutes the backbone of most wireless networks, wireless systems appeal the most to the dynamic and rapidly evolving requirements of today's communication systems because of their ease of deployment and mobility, not to menti ...

Connect or Not: Exploring Seamless Infrastructures through Out-Bodied Interaction

Jeffrey Huang, Selena Savic

Wireless communication relies on high-frequency signal transmission between communication nodes. The signals are at the same time the message and the infrastructure for communication. Questioning the current wireless signals space occupancy in a playful wa ...

Rigidity of equality cases in Steiner’s perimeter inequality

Maria Colombo

Characterization results for equality cases and for rigidity of equality cases in Steiner’s perimeter inequality are presented. (By rigidity, we mean the situation when all equality cases are vertical translations of the Steiner symmetral under considerati ...

Building Wireless Network Coding Protocols

Lorenzo Keller

This work studies how to build wireless network protocols that achieve better reliability, lower delay and higher throughput than existing alternatives by using network coding and by exploiting the broadcast nature of the wireless channel. In the first par ...

Hierarchical Beamforming for Large One-Dimensional Wireless Networks

Olivier Lévêque, Alla Merzakreeva

We consider a wireless network with a large number of source-destination pairs distributed over a line. Under line-of-sight propagation, this network has only one degree of freedom for communication. At high SNR, this one degree of freedom can be readily a ...

Application of a meteorological wireless sensor network to a small alpine watershed

Martin Vetterli, Marc Parlange, Steven Vincent Weijs, Guillermo Barrenetxea Kobas, Raphaël Mutzner, Silvia Simoni

This study focuses on the spatial variability of meteorological parameters in an alpine watersehd in the Swiss Alps, where a wireless sensor network has been deployed. We present some results from the previous summer campaigns, sharing experiences and chal ...

Secure key exchange in wireless networks

Christina Fragouli, László Czap

We investigate the problem of exchanging a se- cret key within a group of wireless devices. In particular, we are interested in information theoretically secure key exchange schemes that enable honest nodes of a multi-hop network to establish a secret grou ...
