In this paper, we propose a new consistency maintenance scheme for P2P file sharing systems which allow end-users to update shared files. The basic idea of the proposed scheme is to construct a static tree for each file to efficiently propagate the update information to all replica peers. The link to the root in a tree is acquired by referring to a Chord ring which registers the mapping from the set...
In this paper, we propose a distributed scheme to realize a quick update of the AOI (Area Of Interest) of players participating in a MMORPG. The basic idea of the proposed scheme is to dynamically adjust the number of master peers in each region using a threshold-based merge and split mechanism, where region is a part of the game field obtained by statically partitioning it. The result of simulations...
