Our paper, “Experimental Performance Analysis of Two-Hop Aerial 802.11 Networks” is accepted in IEEE Wireless Communication and Networking Conference 2014.
The paper focuses on deployment of standard WLAN technology for different network setups over an aerial network. It is experienced that certain setups not only offer network range extension, but also much lower variance in throughput. It is also seen that the standard routing protocol for 802.11s mesh lacks vastly in its implementation when applied to multihop aerial networks. Thus, there is a need to evaluate alternative mesh routing protocols that cater for aerial communication network demands.
Christian Bettstetter and I have organized the Sixth Lakeside Research Days on Multi-UAV Systems. The event was hosted by Lakeside Labs and the University of Klagenfurt in Klagenfurt, Austria, from July 8 to 12, 2013.
We have demonstrated a multi-UAV coverage scenario with three quadrotors working together to make an overview image of a large area. The vehicles were equipped with cameras and they followed pre-computed flight paths, taking high-quality pictures at certain points. The collected images were immediately transmitted to a ground station, where the mission progress could be readily overseen and changed if necessary.
Check out our multi-UAV system in action! The video was nominated for Best Student Video in AAAI (http://www.aaaivideos.org/2013/) and was awarded second place.
Our paper entitled “Medium Access with Adaptive Relay Selection in Cooperative Wireless Networks” with Helmut Adam and Christian Bettstetter has been accepted for publication in IEEE Transactions on Mobile Computing.
