摘要：The Mobile Computing is a vision of future that promises to modify the way
people work and interact today. It has emerged as a new field, distinct from
conventional distributed computing by its focus on mobility and its consequence.
The physical and logical mobility allows the creation of applications with news
requirements: built-in mobility, adaptability and flexibility. So, software
production for this global mobility is complex. Challenges include designing
applications which service levels and available resources are unpredictable, and
the behavior is variable in time and space. To provide a system
architecture that simplifies the task of implementing the mobile applications
with adaptive behavior is the objective of the ongoing ISAM Project. In
order to achieve its goal, ISAM uses as strategies: (a) integrated
environment that provides a programming paradigm and its execution environment;
(b) uniform treatment of adaptation through multilevel collaborative model,
in which both the system and the application contribute for that. The scheduling
