Abstract
Recently, there are technical advances of CPS such as Real-time and Embedded Systems, Sensor Networks, and Information Systems. All the components in CPS are connected with each other to distribute and propagate data. So, CPS is necessary for the technologies of Data Communication Middleware to handle massive data exchanges efficiently. Although there are a number of traditional publisher/subscriber communication middleware, they have some problems in real-time and Quality of Service. Now we introduce the DDS as a middleware of CPS and implement it considering the features for optimization such as memory management, thread management, and lock free. In this paper, we propose a new memory management to enhance the performance of the DDS.
