communication frequently suffers from severe variations in transmission delay and high packet loss rates. In such environments, the use of Delay Tolerant Networks (DTNs) is considered promising as an information delivery method. DTNs achieve data delivery by storing messages and forwarding them opportunistically as nodes move. However, to realize multi-hop communication among multiple mobile nodes in underwater environments, improvements in end-to-end data delivery performance are required. In this study, we address this challenge by proposing a redundant packet allocation method that dynamically adjusts redundancy using Reed-Solomon coding based on quantified communication conditions derived from received signal strength indicator (RSSI) measurements. Each node periodically transmits beacon messages and measures the RSSI of received beacons. An exponential moving average of the RSSI values is calculated to quantify the communication quality. Based on this metric, the transmitting node determines the required number of redundant packets for communication with the receiving node. We implement the proposed method on Raspberry Pi devices and evaluate its effectiveness in a terrestrial experimental environment that emulates underwater communication conditions.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2026-02-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"16","bibliographicVolumeNumber":"2026-IOT-72"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"id":2007393,"updated":"2026-02-16T07:50:11.066345+00:00","links":{}}
