A probabilistic joint energy and spinning reserve market model

Sidi-Rachid Cherkaoui, Ali Ahmadi Khatir

Both deterministic and probabilistic approaches can be used to establish spinning reserve requirements. It has been proved that determining reserve requirements based on probabilistic approaches results in more economical efficiency. So, a probabilistic se ...

SensorTune: a Mobile Auditory Interface for DIY Wireless Sensor Networks

Jean-Pierre Hubaux, Jeffrey Huang, Julien Freudiger, Guillaume Zufferey, Enrico Costanza, Jacques Panchard

Wireless Sensor Networks (WSNs) allow the monitoring of activity or environmental conditions over a large area, from homes to industrial plants, from agriculture fields to forests and glaciers. They can support a variety of applications, from assisted livi ...

Collaborative routing in mobile partitioned networks

Natasa Sarafijanovic-Djukic

Embedded wireless networks find a broad spectrum of applications in transportation, environmental monitoring, logistics, supply chain management, and "pocketswitched" communication. The node mobility patterns in these applications tend to give rise to spat ...

Elucidating the Instability of Random Access Wireless Mesh Networks

Patrick Thiran, Adel Aziz

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 impac ...

Mobility-centric design of collaborative transportation systems

Embedded sensors and actuators are revolutionizing the way we perceive and interact with the physical world. Current research on such Cyber-Physical Systems (CPSs) has focused mostly on distributed sensing and data gathering. The next step is to move from ...

Neighbor Discovery in Wireless Networks and the Coupon Collector's Problem

Ramin Khalili

Neighbor discovery is one of the first steps in the initialization of a wireless ad hoc network. In this paper, we design and analyze practical algorithms for neighbor discovery in wireless networks. We first consider an ALOHA-like neighbor discovery algor ...

On uncoordinated wireless ad-hoc networks : data dissemination over WIFI and cross-layer optimization for ultra wide band impulse radio

Alexandre Fawal

Emerging pervasive wireless networks, pocket switched networks, Internet of things, vehicular networks and even sensor networks present very challenging communication circumstances. They might involve up to several hundreds of wireless devices with mobilit ...
