Monitoring of patients in clinical settings
Presently Sensors are effective for single measurements, however, are not integrated into a “complete body area
Network”, where many sensors are working cumulatively on an individual patient. Mobility is desired, but in many cases sensors have not yet become wireless. This creates the need for the execution of new biomedical personal wireless networks with a common architecture and the capacity to handle multiple sensors, monitoring different body signals, …show more content…
CodeBlue is designed to provide routing, naming, discovery, and security for wireless medical sensors, PDAs, PCs, and other devices that may be used to monitor and treat patients in a range of medical settings. To avoid network congestion and information overload, CodeBlue will support filtration and aggregation of events as they flow through the network.

CodeBlue (depicted in Figure 5) offers a scalable, robust “information plane” for coordination and communication across wireless medical devices. CodeBlue provides protocols and services for node naming, discovery, any-to-any ad hoc routing, authentication, and encryption.

CodeBlue will support a flexible security model allowing a range of policies to be implemented.

CodeBlue will simplify application development by providing a rich infrastructure for connectivity of medical devices. In the hospital, data collected from wireless sensors can be relayed to fixed, wired terminals and integrated with patient records in existing hospital information systems. At a mass casualty site, an ambulance-based system can record extensive data streams from each wireless sensor or PDA to support audits and
