Small unpiloted aircraft (UAVs) each have limited power budgets. If a group (swarm) of small UAVs is organized to perform a common task such as geo-location then it is possible to share the total power across the group by introducing task mobility inside the group supported by an ad hoc wireless network (where the communication encoding/decodeing is also done on fpgas). In this presentation I will describe research into the construction of a distributed operating system where partial dynamic reconfiguration and network mobility are combined so that fpga tasks can be moved to make the best use of the total power available in a swarm of UAVs.
