Rescue and recovery operations are critical in disaster management. For the speedy rescue process in order to save the lives, proper surveillance of the disaster affected area is essential. In this regard, surveillance using Unmanned Aerial Vehicles (UAV's) are predominately helpful in such circumstances for speedy surveillance. In this context, for faster surveillance, multiple UAV's are deployed in the disaster affected region. In this paper, the multiple UAV's are considered as multi-agent systems and explored the algorithms such as UAV back-and-forth algorithm, UAV FA algorithm and UAV random algorithm. The simulation results are carried out and evaluated the algorithms with respect to various parameters such as, residual battery in the drones, number of targets, average hit time and energy consumption. Based on the simulation results, the requirements and the need of the multi-agents for overall efficient surveillance for disaster management can be analysed based on the gathered information.
