Coursework - Essay Example This paper presents results from a research project aiming at developing an architecture supporting local mobility within hospital. The architecture is based on fieldwork and mostly on the knowledge derived from a large number of reliable sources. The fieldwork has emphasized the differences between remote mobility, where users travel over long distances, and local mobility, where users walk around within a fixed set of building. Based on an in depth study, I conclude that local mobility puts up three requirements for computer support;(i) it should integrate into the existing infrastructure (ii) it should support the use of various heterogeneous devices, and (iii) it should enable seamless application roaming between these devices. The paper describes how these requirements were realized in an architecture for local mobility, and how the architecture can be implemented in the health care domain and the costs involved in it and the various benefits gained from it.
