Programming Strategies for Runtime Adaptability

Future advanced embedded computing systems are expected to dynamically adapt applications' behavior and runtime system according to, e.g., usage contexts, operating environments, resources' availability, and battery energy levels. Besides application's functionalities provided by high-level and/or executable binary codes, code for specifying strategies/policies to extend typical functionalities with adaptability behavior is required. A domain-specific language, able to program this adaptability behavior, will allow developers to specify strategies for adaptation, will improve portability, and will help tools to map those strategies to the target system. This paper presents our recent ideas for programming strategies focused on runtime adaptability. The ideas are exposed using extensions to LARA, an aspect-oriented programming language, agnostic to the target language and system. We show examples of using LARA to specify strategies and we comment on the possible implementations to make viable those strategies.
