Many times there is a need to transfer data from remote or inaccessible locations, or in case of emergency, such as fires, earthquakes, floods, when otherwise reliable communications are interrupted. In these cases, drones could be used to act as gateways to transmit data. With this purpose, as part of the master's thesis, we set up a model system that, through the help of drones, provides communication connectivity to the Internet of Things devices located in an area without communication infrastructure. We have designed a communication protocol for routing and packet exchange between drones, which contributes to better connectivity in the delay tolerant networks. We proposed two types of drone movement and two routing protocols. We designed two-phase drone movement with the purpose for optimizing movement in static environments. To demonstrate the feasibility of the model, we have developed a simulation environment that enables system visualization and performance testing.
