Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, store-carry-forward routing schemes which relay a message by combining conventional wired/wireless networking technologies and physical movements of relay nodes, have been proposed. When an access point (AP) forwards a message to a relay node passing near the AP, AP cannot ensure that the relay node passes through the destination node of the message, that is, the success of the delivery will be unknown. In our study, we assume that, for a given message, the AP can perceive a relative magnitude of the probability for a contacted relay node to successfully deliver the message compared with other nodes previously encountered by the AP. Utilizing this information on relative magnitude of success delivery, we propose a message forward scheduling based on the Secretary Problem in which the AP likely selects a relay node with a higher delivery probability while considering a finite lifetime of messages. Through a basic model simulation, we demonstrate that our proposed scheduling improves the message delivery ratio, regardless of the transmission capacity between AP and a node, and mitigates an imbalance of the message delivery ratio among destinations compared with a first-come basis.
