Fuzzy service selection in active networks
P. Bosc, Ernesto Damiani · 2002
The object selection problem requires the evaluation of the fitness of a candidate server object to execute a certain task on the basis of the information about its functional and non-functional features. Active networks store such information in a Trader agent that can be browsed or queried by client objects. In this paper, a fuzzy data model is proposed as the basis of the design of a Trader system. Such a Trader is based on a fuzzy query algebra allowing for deriving operator definitions (and, therefore, query execution mechanisms) at run time, on the basis of user-selected semantics.
