For communication between vehicles and systems, many types of communication mediasuch as Dedicated Short Range Communications (DSRC) and Cellular phones, which have different characteristics such as the range of communicative area, the bandwidth and the cost for communication, can be used. Recently, for exchanging large data between systems and moving vehicles, there are researches for forming a connected area which consists of multiple DSRC communicative areas. In DSRC network where multiple connected areas are scattered along the road, applications are required to have functions for detecting network status, re-sending messages, and so on.For improving development efficiency of applications in DSRC network, so far, we have proposed the middleware with the message delegation system that realizes reliable message delivery based on the information of network status of DSRC network. In this paper, we describe implementation of the middleware and show results of the middleware through evaluation.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"44","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告高度交通システム（ITS）"}],"bibliographicPageStart":"37","bibliographicIssueDates":{"bibliographicIssueDate":"2003-09-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"89(2003-ITS-014)","bibliographicVolumeNumber":"2003"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T23:11:37.760483+00:00","id":45761,"links":{}}
