About

Benjamin Desjardins is a researcher whose work lies at the intersection of robotics, wireless sensor networks, and multi-objective optimization. His primary research focus is on developing robust and reliable strategies for robot-assisted sensor relocation—a critical task for extending the operational lifetime of wireless sensor networks. Desjardins’s major contributions center on formulating sensor replacement as a multi-objective optimization problem, where trade-offs between energy efficiency, travel distance, and network coverage are systematically balanced. His most cited work, "Planning Robust Sensor Relocation Trajectories for a Mobile Robot with Evolutionary Multi-objective Optimization" (2017, 9 citations), introduces methods for generating resilient robot paths that account for uncertainty. This builds on his earlier foundational studies, including "A multi-objective optimization approach to reliable Robot-Assisted Sensor Relocation" (2015, 7 citations), which first framed the problem of replacing damaged sensors with functional spares using a single mobile robot. His 2016 paper on reliable multiple-robot sensor relocation (5 citations) extends this concept to multi-robot teams, enhancing scalability and fault tolerance. While his citation counts reflect a niche but impactful area, Desjardins’s work is notable for pioneering the application of evolutionary multi-objective algorithms to practical sensor network maintenance, offering a systematic framework that balances competing objectives in real-world deployment scenarios.
