C. de  aMobile agent-based systemsban alternative paradigm for distributed systems development.  c1997  ap. 508-516  aAgent-based systems (ABS) constitute an alternative to distributed systems development. The terms agent and agent-based system, although widely used, to do not have yet a consensus definition. This paper presents concepts and a set of characteristics concerning agenthood. Mobility, in addition to the fundamental characteristcs of agenthood, makes mobile agent-based systems (MABS) a unique approach to distributed systems development. Issues regarding frameworks that support mobile agent-bases systems are also addressed in this paper. Finally, a set of existing frameworks is a assessed based on some of the addressed issues.1 aCARDOZO, E.  tIn: SIMPOSIO BRASILEIRO DE REDES DE COMPUTADORES, 15., 1997, Sao Carlos. Anais...
