Mobile Medical Database Approach for Battlefield Environments

摘要

With the advent of portable computers and wireless communication systems, much research has been devoted to mobile computing and database query management. The introduction of portable computers into existing database systems requires traditional transaction mechanisms to be adapted to meet the needs of the mobile user. These mobile users utilise hand-held and laptop computers, which are called mobile hosts, that can access the database from any location at any time. Unlike fixed hosts, the mobile hosts can be "disconnected" from the network for long periods of time. Moreover, advancements in cellular and satellite technology have permitted portable computers to communicate with existing distributed computing networks. Users with palm-top computers, known as mobile hosts (MHs), utilise wireless connections to communicate with wired networks from a number of locations at different times. In this paper, we introduce a mobile database approach and an architecture for a medical battlefield environment. When data is stored on mobile hosts, the mobility issue becomes increasingly more complicated: To deal with this issue, we introduce a transaction manager. (MTM) that is responsible for all the global transactions created by mobile hosts, which contain a portion of the distributed database. A battlefield is a very unique environment due to the fact that the medical units are susceptible to damage and.disconnection from an attack by an enemy force. Prime Time Ⅲ, which is being supported by the Medical Advanced Technology Management Office, is the operational name for the telemedicine support for the US troop deployment in Bosnia. A distributed patient-soldier database provides patient-soldier medical information in real-time. An application of the patient-soldier database is discussed with respect to transaction management in the medical battlefield environment.
