Claim:
1. A method comprising: defining an ad-hoc perimeter to be monitored, the ad-hoc perimeter having at least one curved portion; determining a line tangent to the at least one curved portion; determining a number of autonomous drones for creating a monitoring fence arrangement of the ad-hoc perimeter, each of the autonomous drones including a movement detection mechanism, the movement detection mechanism including a light source and a light detector; determining a position for each of the determined number of autonomous drones, at least one position being based at least in part on the tangent line; transmitting the position to each of the autonomous drones; projecting a light from the light source along the tangent line; monitoring a status of the autonomous drones; transmitting a signal in response to at least one of the autonomous drones detecting a breach of the ad-hoc perimeter based at least in part on detecting movement by receiving with the light detector a reflection of the light by a surface along the tangent line.
