Middleware for ubiquitous Healthcare Information system

Healthcare Information system requirements differ from other existing applications. The gap between existing application and medical care needs makes it more complex. To get the maximum benefit of Ubiquitous healthcare system it is necessary to build a Middleware between different ubiquitous applications which can play an important role in management of data and information processing. To enable medical personal for real-time triage, correlation with hospital records and long-term observation of patients is necessary, while sharing the most accurate and real-time patient information. The technology requirements of various domains are increasing, such as distributed platforms are commonly in use, the quality of service requirements for ubiquitous Healthcare systems are increasing as the low level sensor network grows powerful, customers ask for platform independent software and interoperability, etc. Middleware is a class of software technologies designed to help manage the complexity and heterogeneity inherent in distributed systems. It is defined as a layer of software above the operating system but below the application program that provides a common programming abstraction across a distributed system. Middleware can be classifying into two levels, low level middleware and high level middleware. Low level middleware exist between different sensor node, raw data and their application. High level middleware exist between different application which is used for exchange data and communication between various applications. If we first take the consideration then we find there is great work has been done on low level middleware and their different technology. Like Mobiware, ALICE, CAMUS, MiLAN etc. but if we talk about high level middleware then we find there is not good work has been done. And we find that without the proper research of this field we can not achieve the real ubiquitous healthcare system. In this paper, we present a review of the low level and high level middleware literature and then enumerate these common features and then we briefly presents our own middleware system and how it relates to these features.
