in the last two decades, the trend in healthcare information technology has been towards digital and multimedia concepts. the next generation of healthcare information systems will consist of a vast network of heterogeneous, autonomous and distributed imaging scanners, hospital information systems (his), medical information from clinical departments such as radiology information systems (ris), ...

background: hospitals employing telesurgery need to be evaluated to determine whether they satisfy the international standards. the main goal of this research was to assess the software, hardware, telecommunication equipments, privacy and security methods, and staffing requirements for supporting and executing telesurgery in hospitals affiliated to tehran universities of medical sciences, tehra...

Man, is living in an era that the knowledge is estimated to be doubled in a relatively short time. The fast rate of technology's growth in the "Century of information", is caused by fast growth of communication technologies like the internet which has become one of the best tools for a quick, cheap, effective and vastly supported communication. For an efficient and effective usage of tools and ...

Routing is an important challenge in WSN due to the presence of hundreds or thousands of sensor nodes. Low Energy Adaptive Clustering Hierarchy (LEACH) is a hierarchical routing and data dissemination protocol. LEACH divides a network domain into several sub-domains that are called clusters. Non-uniformity of cluster distribution and CHs selection without considering the positions of other sens...

Routing in computer networks has played a special role in recent years. The cause of this is the role of routing in a performance of the networks. The quality of service and security is one of the most important challenges in routing due to lack of reliable methods. Routers use routing algorithms to find the best route to a particular destination. When talking about the best path, we consider p...
