Using Location Services to Autonomously Drive Flying Mobile Sinks in Wireless Sensor Networks

The use of mobility in a Wireless Sensor Network has already
been indicated as a feature whose exploitation would increase the performances
and the ease of mantainance in these environments. Expecially
in a event-based WSN, where is necessary a prompt response in terms
of data processing and offloading, a set of mobile flying sinks could be a
good option for the role of autonomous data collectors. For those reasons
in this paper we propose a distributed algorithm to independently and
autonomously drive a mobile sink through the nodes of a WSN and we
show its preferability over more classical routing approaches expecially
in the presence of a localized generation of large amount of information.
Our result shows that, in the case of fairly complete coverage of the area
where the nodes lie, it is possible to promptly notify a mobile sink about
the presence of data to offload, drive it to the interested area and achieve
interesting performances.
