Research of Key Technologies of Universal Middleware for Wireless Computing

To shield heterogeneous and distribution of system and improve the efficiency of development, middleware technology has been successfully applied to the traditional distributed system. But in the wireless sensor network environment, traditional middleware technology is facing enormous challenges such as dynamic environment, network asymmetry, frequent disconnection, limited resources, and wide diversity of context. Therefore, it is important to design the universal middleware for massively heterogeneous wireless sensors. It can improve the system performance and efficiency and provide effective extension and expansion for traditional middleware. In this paper, we introduce the system structure of the universal wireless middleware platform, which is divided into infrastructure middleware and application service middleware. Meanwhile the key technologies of the middleware platform for wireless computing environment are analyzed.
