Abstract

Collecting
data in remote ecosystems such as mangrove estuaries, rainforests, deep-water habitats and river flowstreams requires high coverage
and spatiotemporal precision. While satellite systems enable high coverage, they lack precise spatiotemporal data collection. Swarms of
drones have emerged as a promising way to improve the precision of data collection. However, designing drone swarms as fault-
tolerant remote sensing platforms remains challenging. This doctoral project addresses a key research issue for these platforms: fault-
tolerant data dissemination. The project will investigate and propose mission-oriented dissemination techniques to enable adaptive
sensing data collection ranging from low-latency, fast data collection to partition-tolerant, delay-tolerant remote sensing applications.

Context and proposed research

Effective environmental data collection and dissemination in drone swarms relies heavily on distributed synchronisation mechanisms that allow nodes to exchange state, maintain a consistent view of shared data, and support collective decision making. This requirement is particularly challenging in mobile settings, where communication links are intermittent, network topology changes frequently due to mobility, and available bandwidth and energy resources are limited. Additionally, the CAP Theorem [Gilbert and Lynch 2012] states that a distributed system can simultaneously satisfy at most two of the following properties: consistency, availability, and partition tolerance. In highly dynamic swarm networks, network partitions are frequent and largely unavoidable, which makes it difficult for traditional strongly consistent systems to maintain high availability. As a result, such systems are hard to deploy efficiently in drone swarms, where continuous operation and timely coordination are essential. Multicast primitives [Janic 2005] are fundamental for information dissemination in networked systems. These primitives allow drones to synchronise their collected data and to enable fault tolerance through replication. As drones communicate through a sparse, wireless ad hoc network, we assume that state synchronisation messages are exchanged through unreliable channels to reduce synchronisation costs. To explore novel primitives suitable for drones swarms, this project has three main goals. Firstly, we aim to survey data dissemination techniques for environmental monitoring. Secondly, we aim to design novel, adaptive protocols for drone swarms based on the ecosystems to be monitored. Thirdly, we expect to validate the techniques with a proof of concept.

Additional Information

This fully-funded PhD starts in September 2027 and the duration of the contract/scholarship is 3 years. Benefits include:

• French government strongly subsidizes its higher education system, therefore therefore the tuition fees are among the more competitive in Europe. Moreover, our program grants tuition fee waiver at UFPB in Brazil.
• Social security coverage included.
• Dedicated funding to support research, training, networking and international mobility activities, including allowance to cover flights and living expenses for up to 12 months in Brazil.
• Partial reimbursement of public transport costs.
• Social, cultural and sports events and activities.

Eligibility criteria

Academic Requirements: By the call deadline, candidates must hold a master’s degree or equivalent diploma; and must not hold a doctoral degree.

Mobility Rule: Applicants must not have resided or conducted their primary activity (work, studies, etc.) in the France for more than 12 months in the 36 months preceding the call deadline. Periods of stay as a tourist, refugee, or time spent in national service, are not considered as residency.

• Letter of motivation that should describe the applicant's background in the areas of the project, reason for interest in the project, and future plans
• A list of courses and grades of the last three years of study (an informal transcript is OK).
• Names and contact details of at least two people who can write you references, whom we will contact directly.
• If relevant, a link to your publications and/or open-source developments.

The selection process is three-fold:
