<i>Boxed Ambients</i> are a variant of Mobile Ambients that result from dropping the open capability and introducing new primitives for ambient communication. The new model of communication is faithful to the principles of distribution and location-awareness of Mobile Ambients, and complements the constructs in and out for mobility with finer-grained(More)
Boxed Ambients (BA) replace Mobile Ambients'ÓÔÒ capability with communication primitives acting across ambient boundaries. Expressiveness is achieved at the price of communication interferences on message reception whose resolution requires synchronisation of activities at multiple, distributed locations. We study a variant of BA aimed at controlling(More)
—Service Oriented Architectures draw heavily on techniques for reusing and assembling off-the-shelf software components. While powerful, this programming practice is not without a cost: the software architect must ensure that the off-the-shelf components interact safely and in ways that conform with the specification. We develop a new theory for adaptable(More)
Boxed Ambients are a variant of Mobile Ambients, that result from (i) dropping the open capability and (ii) providing new primitives for ambient communication while retaining the constructs in and out for mobility. The new model of communication is faithful to the principles of distribution and location-awareness of Mobile Ambients, and complements the(More)
