Resumo: The distributed computing environment today is characterized by increasing diversity, the dynamism and increasingly complex applications. Applications for this type of environment they need autonomy to conduct management activities such as installation, configuration and maintenance, with the aim of decreasing the cost and effort involved in such activities. In mobile environments, for example, applications need to adapt due to changes in the environment (available bandwidth, signal level, etc..), Which can affect the quality of service offered to users. This paper presents a proposal for self-adaptation based on the architecture of Meta-ORB reflective middleware. The fluffy main purpose is to provide support to self-adaptation for applications that have requirements of service quality. In this paper, the concept of adaptation policies was introduced in the meta-model middleware, allowing the developer to define both the model of adaptive behavior as their applications using the same modeling language. This unified model is available at run time, being used by a mechanism of self-adaptation to the embedded middleware. The proposed architecture was implemented in a prototype called MetaORB.NET, employed in a case study to evaluate the use of architecture in the development of self-adaptive applications
