A Scalable Pervasive Computing Architecture for Hospital Information System Based on Multi-weight Virtual Machine
Yuanfei Chen, Zhenmin Zhu, Ji Quan Teng · 2008
A new multi-weight virtual machine based on pervasive computing architecture has been introduced to support the future hospital information system in pervasive computing age. In this architecture, four running modes are defined according to the terminal's hardware performance and the weight of the applications. To realize the architecture, some prototypes have been developed. Compared with the traditional PC-based architecture, VM-based architecture has many advantages in TCO, manageability and availability.
