In this paper, we propose a method to deploy wireless network surrounding a target building. Nodes are attached to balloons outside a building and deployed in the air so that the network can be accessed from anywhere in the building. In order to address the three-dimensional deployment problem, the proposed method optimizes an objective function for minimizing the number of network nodes on guarantee the coverage. For solving this problem, we propose an algorithm based on a genetic algorithm. We also introduce an original radio propagation model for predicting path loss from an outdoor position to a position inside a building. To evaluate the proposed method, we compared our method with three benchmark methods, and the results show that the proposed method requires 18-50% fewer nodes than other methods under the same execution time. Moreover, we confirmed that the error rate of radio coverage is about 6% through a real world experiment.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_publisher_10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人情報処理学会","subitem_publisher_language":"ja"}]},"item_7_rights_11":{"attribute_name":"出版者URL","attribute_value_mlt":[{"subitem_rights":"http://id.nii.ac.jp/1001/00102563/"}]},"item_7_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
