چکیده

Over the past years of research various layers of programming abstraction for networked sensor systems have evolved and the motivation of macro-programming is discussed. Among several recently proposed macro-programming techniques, the abstract task graph macro-programming framework was developed to alleviate application developer work when creating a wide range of wireless sensor network applications. However, its underlying runtime system currently supports only initial task placement onto the nodes of the target network. Since sensor networks operate in a dynamic environment, runtime system should be improved to support the migration of tasks based on energy situation in the networked sensor system. In this paper, an approach for task migration in the runtime is proposed. To achieve this goal, a set of abstract task annotations is extended with migration elements, runtime system is complemented with task migration components, and destination node selection method for the task to be migrated is provided.
