Project description

The occurrence of natural disasters, such as earthquakes, often have long-lasting repercussions in terms of damages to existing communication infrastructure, thus hampering coordination in search and rescue efforts. Consequently, it is crucial for emergency workers to have a rapidly deployable communication network in place to support rescue operations. In such scenarios, a swarm of powered fixed-wing drones may be employed to form a communication mesh, to hop messages across a large area [1]. Some of the drones in the swarm may also be allocated as runners, to physically fly information from one zone to another. However, the operability of such a communication network is severely constrained by the limited endurance on individual drones.

The proposed PhD project considers an alternative solution through the exploitation of thermal columns by aerial gliders [2,3]. Thermals are columns of upward moving air-currents in low altitudes of the earth’s atmosphere, caused by the uneven heating of the earth’s surfaces (see [4] for model of thermals). They typically occur above dark regions of the earth’s surface -- absorbing more heat. Gliders may exploit the thermals as a source of lift, gliding from one thermal column to another to remain airborne. For a human pilot, localizing a thermal is a complex process involving many subtle cues, thus being difficult to replicate in an autonomous glider. However, a swarm of gliders, spread out across a large expanse, may be able to guide each other into thermals they have flown into [5]. The project aims to create such a constellation of gliders to cover a large expanse of land with a communications relay. 

The following challenges will be addressed in the project:

a. Develop simulation framework of a UAV swarm and dynamically evolving thermals.

b. Develop computationally and communication efficient swarm coordination algorithms for a large-scale (50-100) swarm of low-cost gliders to maximize their time in the air, while maintaining a dynamically changing, distributed map, of the location of discovered thermals.

c. Evolving coordinated responses of the swarm to changing environments.

d. The swarm communicating to a human operator the “health” of the communication relay, and whether additional gliders need to be launched from the base station.

Key skills Strong programming skills, good math and statistical analysis.
