| Research Abstract |
Mobile code is now a popular abstraction mechanism to construct adaptable distributed systems in convenient way. To develop a system using mobile code, on has to overcome several new complexities (as well as security and safety problems) in his/her code arise from the mixed use of mobility primitives. In this research, we claim the need for appropriate support for mobility aspects and discuss how to modularize them using compile-time/run-time metalevel architectures. We have designed and implemented a modular, generic fault-handling mechanism for mobile code systems. The mechanism is based on a simple per-object metalevel architecture. We also consider safety issues on dynamic adaptability of component-based software systems and have proposed an architecture for safe dynamic adaptability.
