....essentially because this technology greatly relies on portable implementation techniques, relatively little prior work exists on how agents may additionally adapt themselves to take the specificities of their local execution environment into account . The DAS dynamic adaptation model [2] proposes to enable mobile agents to adapt in the middle of their execution to asynchronous events of all kinds. The focus is however not on semantic interoperability, but on how to be aware of changes (especially of hardware and temporal contraints) and to react correctly. Adaptability is ....

....environments. However, it is hard to control inside behavior of each software system from its outside. Thus, each software system should have the ability to adapt itself to the changes. We call the ability dynamic adaptability. We have proposed a software model with dynamic adaptability named DAS[2] and its description language named LEAD [3] In this paper, we consider about safety issues on dynamic adaptability of software systems based on mobile code and propose an extended DAS model named Safe DAS. The safety means that adaptable behavior in the software systems does not violate their ....

....software systems with dynamic adaptability not only adapt themselves to dynamically changing runtime environments, but also change their own functionalities exibly to make full use of the properties in the runtime environments. We have proposed a software model with dynamic adaptability called DAS[1, 2] and its description language LEAD [3] The DAS model is a re ective software model, and LEAD is an object oriented re ective language based on Java. Using LEAD , we can construct component based software systems with dynamic adaptability (called dynamically adaptable software systems) in ....

The mechanism to instantiate components in runtime (Plug Play) The mechanism to change inside behaviors of a component in runtime. 3 Overview of LEAD We have proposed a software model with dynamic adaptability called DAS[1, 2] and its description language LEAD [3] The DAS model is a re ective software model, and LEAD is an object oriented re ective language that is an extension of Java. The syntax of LEAD is based on Java with some additional extensions. The prototype of LEAD is a pre processor of Java. LEAD ....

....systems with dynamic adaptability not only adapt themselves to dynamically changing runtime environments, but also change their own functionalities exibly to make full use of the properties in the runtime environments. We have proposed a software model with dynamic adaptability called DAS [1] and implemented a glue language system LEAD [2] based on the model. 2 The DAS model The following are main concepts of the DAS model. The basic components of adaptable behaviors are procedures, and the control of adaptable behaviors is based on procedure s invocation. The DAS model has a ....
