Our distributed storage middleware is built in the user space (as an app, no changes to the OS) of mobile, portable and embedded devices. When activated, it transforms a device into a storage node of an ad-hoc storage service (made by the other devices running the same middleware). The current version of the middleware exploits the HEAVEN communication middleware to coordinate the operations of the multiple devices running the distributed database service.

Although the adoption of surveillance drones seems to continuously increase these days, especially within the public security sectors, their limited battery autonomy considerably hinders their performance and restrains their use to short duration missions.

A fleet of drones receives the command from one operator to patrol a defined zone from above for extended view.

A specific coverage percentage rate is calculated by embedded AI algorithms to ensure the target zone can be protected by the drones of the fleet.
