| Abstract(in English) | We propose the delay tolerant message delivery system using unmanned aircraft systems (UAS) that is capable to establish communications between surviving and isolated areas caused by the disaster. Wi-Fi is considered to be used for communications between user terminals and UAS. We assume that the wireless environment of the ground is different from that of UAS flying with an altitude of several hundred meters. In this paper, we measure Wi-Fi performances affected by the difference between wireless environments of the ground and upper air and investigate communication characteristics of the ground and upper air by computer simulations. Results reveal that in order to let UAS easily receive signals of Wi-Fi devices located in a wide area, performance degrades significantly due to packet collisions caused by the hidden terminal in the upper air. |
