Ti Experimental results are typically envisioned as the ultimate validation reference for any theoretical and/or simulation modelling assumptions. However, in the case of Wireless LANs, the situation is(More)
We propose a powerful MAC/PHY cross-layer approach to measuring IEEE 802.11 transmission opportunities in WLAN networks on a per-link basis. Our estimator can operate at a single station and it is able to: 1) classify losses caused by noise, collisions, and hidden nodes; and 2) distinguish between these losses and the unfairness caused by both exposed nodes(More)
Driven by the miniaturization and advancement of computing, communication, and sensing units, commodity micro aerial vehicles (MAVs) enable manifold exciting new services. Being small unmanned aerial robots with a weight up to a few kilograms, MAVs feature embedded processing, various sensors, and movement in 3D space. MAVs can perform planned missions(More)
Wireless local area networks have been designed for wireless communication. Frames are acknowledged (ACKed) after a short and predefined MAC idle time. The MAC idle time varies with i) the physical distance between stations, caused by the delay of wireless signal propagation, and ii) the time to detect the ACK at the local station, which varies with the(More)
Offloading traffic through opportunistic communications has been recently proposed as a way to relieve the current overload of cellular networks. Opportunistic communication can occur when mobile device users are (temporarily) in each other’s proximity, such that the devices can establish a local peer-to-peer connection (e.g., via Bluetooth). Since(More)
Outdoor WLAN communication is envisioning an increasing interest, due to the massive emergence and deployment of outdoor wireless Mesh Networks. This paper provides a report on an extensive measurement campaign carried out in an outdoor Wireless LAN Campus scenario. A public domain driver, namely MADWiFi, has been modified in order to achieve a high(More)
Aggregating multiple 802.11 Access Point (AP) backhauls using a single-radio WLAN card has been considered as a way of bypassing the backhaul capacity limit. However, current AP aggregation solutions greedily maximize the individual station throughput without taking fairness into account. This can lead to grossly unfair throughput distributions, which can(More)
Though there has been a lot of interest in Visible Light Communication (VLC) in recent years, a reference platform based on commercial off-the-shelf components is still missing. We believe that an open-source platform would lower the barriers of entry to VLC research and help the VLC community gain momentum. In this paper we take an initial step toward the(More)
In Search And Rescue missions, Unmanned Aerial Vehicles (UAVs) equipped with cameras allow for efficient scanning of large areas. Yet, delivering high resolution images to rescuers also requires high-speed communication. In this paper, we investigate the potential and challenges of wireless communication between UAVs in such scenarios. Our fleet of UAVs(More)
Visible Light Communication (VLC) is an emerging technology in which Light Emitting Diodes (LEDs) transport information wirelessly, using the visible light spectrum. While most of the research on VLC has focused on wideband white LEDs used in ambient illumination, narrowband and colored LEDs have received little attention. Short-range free-space optical(More)
