Abstract

災害時に携帯電話や小型センサデバイスどうしで無線通信を行い,緊急情報の伝搬や被災者のバイタルサイン情報を救援者(救助隊や医療班)に迅速に伝搬させ,災害時の救命救急作業の高度化を目指した様々な研究開発が進められている.本論文では,まず災害現場で無線通信端末を持つ被災者や救援者の行動を形式的に記述するためのモデルを提案する.提案モデルは,災害現場の被災状況や被災者らの行動範囲の動的な変化を指定する地理モデル,被災者や救援者らの行動パターンを記述するためのノードモデル,対象とする救援活動の内容を指定するシミュレーションシナリオから構成される.次に,これらのモデルを無線ネットワークシミュレータMobiREAL上に導入し,そのシミュレータを用いて,無線通信端末上で動作する実アプリケーションの動作や性能を検証する機能も実現した.提案モデルを用いた評価実験により,災害現場を再現したもとでの無線通信端末の有無による救命支援システムの評価が容易に行えることを示せた.また,400ノードからなるネットワークシミュレーションを介した実アプリケーション動作実験では十分小さい遅延で実アプリケーションの通信が実現できることを示した.In this paper, we propose a new simulation environment to evaluate computersupported life-saving activities in disaster area. The environment includes the modeling of human behavior, their activities and dynamic change of geographical regions' attributes in disaster areas as well as a disaster scenario description language. These models have been implemented into our wireless network simulator MobiREAL along with a function to simulate communication traffic of application programs running on real terminals. Experimental results have shown that the proposed environment facilitated the evaluation to assess effectiveness of life-saving activities using networked applications. Furthermore, simulation of application traffic could be done with reasonable simulation delay, which did not affect the performance of the application.
