To overcome this problem, a method to permit mobile nodes to transmit information only in transmittable areas has been considered. This method is called Information Floating. Theoretical analysis of Information Floating is important because it is necessary for some purposes such as control of the size of a transmittable area, and has been studied in various situations. In this paper, we consider Information Floating by pedestrians walking toward opposite directions along a street, and theoretically analyze performance of Information Floating under the assumption that the communication range changes due to the positional relationship between mobile nodes because the mobile nodes themselves become obstacles. From the numerical results, we show that degree of effects of the assumption that mobile nodes themselves become obstacles on performance of Information Floating depends on the densities of mobile nodes and the difference between the densities of mobile nodes moving toward the opposite directions, and show effectiveness of the proposed theoretical method. Based on these results, we show a method to decide the size of a transmittable area suitable to the situation where mobile nodes themselves become obstacles.</p>"},{"@language":"ja","@value":"<p>歩行者や自動車などの移動ノードが，直接無線通信及び情報を持つ移動ノードの移動により情報を空間的に拡散させ伝達する場合，無秩序かつ不必要な情報拡散が発生する．この問題を防ぐため，直接無線通信による情報の送信場所を送信可能エリアだけに制限して伝達することが考えられ，この手法は情報フローティングと呼ばれている．情報フローティングの理論性能評価は，送信可能エリアの大きさの決定などに必要なことから重要であり，様々な状況を仮定し，研究されてきた．本論文では，道路上を双方向に移動する歩行者群による情報フローティングを考え，通信を行う移動ノードの位置関係によって移動ノード自身が障害物になり直接通信可能距離が異なる場合の情報フローティングの理論解析を行う．理論解析の数値計算結果より，移動ノードの密度及び各方向の密度の違いによって移動ノード自身が障害物になることの情報フローティングへの影響の程度が異なることを示し，本論文の理論解析手法の有効性を示す．この結果を踏まえたうえで，移動ノード自身が障害物になる状況に適した送信可能エリアの大きさの決定法を示す．</p>"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420845751149380480","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"30313505"},{"@type":"NRID","@value":"1000030313505"},{"@type":"NRID","@value":"9000004798738"},{"@type":"NRID","@value":"9000408427173"},{"@type":"NRID","@value":"9000399755009"},{"@type":"NRID","@value":"9000415219829"},{"@type":"NRID","@value":"9000399754408"},{"@type":"NRID","@value":"9000414938241"},{"@type":"NRID","@value":"9000403023990"},{"@type":"NRID","@value":"9000408634635"},{"@type":"NRID","@value":"9000399755035"},{"@type":"NRID","@value":"9000399754429"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/KARASAWA-Naoyuki"}],"foaf:name":[{"@language":"en","@value":"Karasawa
