Abstract
In this paper, we propose a new map-based content sharing system ’MapWiki’ for ubiquitous
content distribution. In MapWiki, users can publish location-dependent information on the map as
Wiki contents which contains links or inline images of the objects in the ubiquitous environment by
simple formatting rules. The status change of the content are updated on the map in real-time which
enables users to communicate between real field and virtual environment. Publishers and receivers
are authenticated using social network to ensure the trustfulness of the content. We have
implemented MapWiki on Google Maps and evaluated its effectiveness. We also propose a
distributed P2P-based content management method to manage locationdependent information of
GMapWiki. In this content management method, each user stores his or her own locationdependent
content in the local computer. This P2P-based content management method realizes scalability,
flexibility and privacy of the GMapWiki system. We have enhanced a P2P networking method called
‘LL-Net’ to implement a prototype system and confirmed its feasibility.
