NODE AND EDGE DRONE SURVEILLANCE PROBLEM WITH CONSIDERATION OF REQUIRED OBSERVATION QUALITY AND BATTERY REPLACEMENT

Node and Edge Drone Surveillance Problem With Consideration of Required Observation Quality and Battery Replacement

Our study introduces a drone routing problem in Replacement Wick which drones fly to capture photos for surveillance purposes after a disaster.The drones perform observations on nodes and edges representing populated areas and road segments of a network from multiple altitudes.Each target node and edge requires observation at least once with a cert
