About

Raju Shrestha is a leading researcher at the intersection of wireless communications and autonomous robotics, with a primary focus on radio map estimation. His work addresses a critical challenge: how to efficiently and accurately construct spatial maps of radio frequency metrics—such as received signal strength—using minimal, intelligently gathered measurements. Shrestha’s most impactful contribution, “Spectrum Surveying: Active Radio Map Estimation With Autonomous UAVs” (2022, 70 citations), pioneers a novel framework where unmanned aerial vehicles actively plan their flight paths to optimize data collection, dramatically improving map accuracy while reducing surveying time. This active sensing approach has significant implications for resource allocation, interference coordination, and mission planning in dynamic environments. His subsequent theoretical work (2024, 17 citations) provides a rigorous mathematical foundation for the radio map estimation problem, offering bounds and insights that guide future algorithm design. By bridging theory and practical deployment, Shrestha’s research is shaping next-generation wireless systems and autonomous navigation, making him a key voice in spectrum surveying and intelligent sensing.
