| Abstract(in English) | In energy harvesting delay tolerant networks (DTN), each node carries, stores, and forwards messages to other nodes while charging its battery with energy harvesting technology. By utilizing the energy harvesting DTN, messages can be transmitted to other users in unstable network environments where frequent disconnections occur. Currently, in the energy harvesting DTN, unmanned aerial vehicles (UAV) is expected to be used as a mobile node. Here, we consider a DTN system where messages are transmitted by using multiple UAVs that can charge the battery with energy harvesting technology as a node. In such a system, each UAV should decide whether a message is forwarded or not by considering its battery and the number of transmissions. In this paper, we propose a message forwarding method based on Markov Decision Process (MDP). In the proposed method, an UAV decides the optimal action based on the battery and the number of transmissions. In numerical examples, we investigate the performance of the proposed method and show that an UAV can decide the optimal action according its state. |
