Özet: In recent years, the problem of designing a cooperative communication system to support a swarm of Unmanned Aerial Vehicles (UAVs) is a major research challenge. In this paper, we present a time-effective approach for multiple UAVs conducting a collaborative search algorithm, this approach is targeted for sensing the disaster zone and finding the survivors in most efficient manner. In this respect, we consider a swarm of autonomous quad rotor UAVs that serve as a mobile sensors; communicate through a wireless link and equipped with a sensing devices. We aimed in this approach for the cooperative UAVs to coordinate their actions and behave as an intelligent array of sensors during the searching, detecting, and locating survivors. This approach has the ability to move the UAVs to the required location and finally achieving a cooperative decision making.  A simulation of cooperative quadrotor UAVs is implemented using the Optimized Network Engineering Tool (OPNET). We develop a module for each UAV in which it is responsible for searching, detecting, and locating survivors. Moreover, this module is responsible for the wireless communication between the quad rotor UAVs. Performance of a cooperative decision making technique is observed when communication range and number of UAVs are varied. The results indicate that the number of quadrotor UAVs was found to have the greatest impact on the total time that is taken for detecting, and locating survivors. The findings demonstrate that the proposed approach can be used to search a large disaster zone in a very short time.
