Abstract:  Unmanned aerial vehicles have become cheaper because many control functions can be implemented in software rather than having to depend on expensive hardware . This even allows multiple UAVs to be used for a single application. In this case, the UAVs must have communication facilities so that they can communicate with each other. This can easily be achieved by equipping an UAV with a wireless mesh node. In this scenario, the UAV swarm can be considered to be a highly mobile wireless mesh network. In this paper we propose an architecture based on unmanned aerial vehicles (UAVs) that can be employed to implement a control loop for agricultural applications where UAVs are responsible for spraying chemicals on crops. The process of applying the chemicals is controlled by means of the feedback from the wireless sensors network deployed at ground level on the crop field. The aim of this solution is to support short delays in the control loop so that the UAV spraying can process the information from the sensors. Further more ,we evaluate an algorithm to adjust the UAV route under changes in the wind (intensity and direction) and the impact related to the number of messages exchanged between the UAV and the WSN. The information retrieved by the WSN allows the UAV to Confine its spraying of chemicals to strictly designated areas. Since there are sudden and frequent changes in environmental conditions the control loop must be able to react as quickly as possible.
