Abstract-In recent years, several researchers have applied wor kflow technologies for service automation on ubiquitous computing environments. However, most context-aware workflows do not offer a method to compose several workflows in order to get more large-scale or complicated workflow. They only p rovide a simple workflow model, not a composite workflow model. In this paper, t he autorhs propose a context-aware workflow model to support composite workflow s by expanding the patterns of the existing context-aware workflows, which supp ort the basic workflow patterns. The suggested workflow model offers composite w orkflow patterns for a context-aware workflow, which consists of various flow p atterns, such as simple, split, parallel flows, and subflow. With the suggested model, the model can easily reuse few of existing workflows to make a new work flow. As a result, it can save the development efforts and time of context-awar e workflows and increase the workflow reusability. Therefore, the suggested mode l is expected to make it easy to develop applications related to context-aware workflow services on ubiquitous computing environments.
