Packages delivered by air: Drones as delivery service

What has travelled by road to reach us until now could be delivered by drones in the future. This has many advantages: Poor rural transport infrastructure or persistent congestion in large cities can be bypassed. In 2013, Amazon was among the first to announce the intention to deliver goods using small autonomous drones. But when might this technology truly become part of our daily lives? Drone researcher Pasquale Grippa provides some answers.

Synchronization in sensor networks using time series analysis

Time synchronization is an essential building block in wireless sensor networks but is challenging due to low-precision oscillators and limited computational power of cheap devices. A novel synchronization solution for such scenarios is now proposed by Wasif Masood together with his advisors Christian Bettstetter and Jorge F. Schmidt from the University of Klagenfurt.

Synchronization with phase rate correction

Synchronization algorithms based on the theory of pulse-coupled oscillators are evaluated on programmable radios. It is experimentally demonstrated that the stochastic nature of coupling is a key ingredient for convergence to synchrony. We propose a distributed algorithm for automatic phase rate equalization and show that synchronization precisions below one microsecond are possible.
