A general architecture of IUCELA is designed to connect multiple sensing devices with location-aware applications. Then the function of location-aware middleware which is the core component of the proposed architecture is elaborated. Finally an indoor forum is taken as an example scenario to demonstrate the security, usefulness, flexibility and robustness of IUCELA.展开更多

If organizations want to remain competitive in today’s fast changing business and technological environment, they must overcome these problems. Middleware is a valuable technology in that it provides convenient methods to construct system infrastructure, so it can be used to migrate the legacy systems. This paper gives a case study on using middleware technologies for the implementation of reengineering distributed and heterogeneous bank legacy system in Anhui branch of China Construction Bank. Using middleware to migrate legacy system has proved to be good choice in practice.展开更多
