Together with process distribution, mobility, remote operations and asynchronous communication through distributed data spaces, the language provides constructs for explicitly modelling inter-node connections and for dynamically establishing and removing them. For the proposed language, we define natural notions of extensional observations and study their closure under operational reductions and/or language contexts to obtain barbed congruence and may testing equivalence. For such equivalences, we provide alternative characterizations in terms of a labelled bisimulation and a trace equivalence that can be used for actual proofs. date: 2005 date_type: published series: Lecture Notes in Computer Science volume: 3580 publisher: Springer pagerange: 1226-1238 id_number: 10.1007/11523468_99 refereed: TRUE isbn: 3-540-27580-0 book_title: Automata, Languages and Programming (ICALP 2005) editors_name: Caires, Luis editors_name: F.
