Abstract
Decentralized tuple space is an e®ective
paradigm for distributed collaborative applications since
its loose decoupling, availability and °exibility in system's
organization. However, there are very few research results
on its replication and consistency. This paper presents
a decentralized tuple space model to enable tuple update
by creating loose update links among decentralized Tuple
space nodes. Besides, tuples are grouped with tuple types,
the unit of being applied a replication policy, which con-
trols the distribution of replicas. The model is simulated
by Desmo-J. The experiments show that applying di®er-
entiate replication policies used for di®erent purposes is
absolutely necessary, because no single policy is suitable
under all use patterns.
