Abstract: This paper presents a self-adaptive evolution model——DESM, which is based on pervasive computing. It describes the structure and function through the internal definition of DESM, and uses graph for the causes of the ubiquitous environment and timing of evolution to model, so as to ensure the consistency of the system. It verifies the feasibility and the effectiveness of the model during an information management system, and describes its internal evolution with timing diagram.

Key words: pervasive computing, self-adaptive, software architecture
