JMED-Uma arquitetura PEER-TO-PEER para aplicações em telemedicina

Abstract

In the last years Research and Development (R&D) in the area of computer systems and communication systems have started a technological revolution which has made it possible to conceive a number of new products, particularly embedded systems, from cell phones to medical equipments. The area which makes use of both technologies above is frequently known as Information Technology (IT). IT has boosted a number of research projects and has established as a research area in its own. Among the applications which have benefited from IT, Telemedicine is one that stands out. Telemedicine is the distribution of medical care, as well as medical knowledge cooperation at distance by using IT. Many solutions proposals to support Telemedicina if base on the architecture Client-Server. This architecture presents low Reliability for the fact to count on a central element (Server) to provide the requested services. It is clearly that redundancy can be incorporated in server level, but to the high price to have itself that to guarantee the consistency of the talked back servers. In this dissertation we propose a communication architecture based on peer-to-peer (P2P) computing, that it decides the problem of the architecture Client-Server. The importance is argued of if to use this technology in offers in the distance of services of specialized medical assistance, considering a direct style of contribution between doctors, from the interconnection between computational equipment. The proposed system, named JMED, was developed using programming platform for distributed P2P computing known as JXTA. JMED was implemented and we showed that is can be used in Telemedicine application by designing an application known as “second opinion”, where computers and cell phones were used as communication stations.
