Medical devices has been using cutting edge technology to provide a better precision and accuracy in monitoring patients and to carry out different operations. Further advancements has led to the introduction of wireless sensing networking devices in medical field.
Introduction of Wireless Sensor Networking:
Advances in wireless sensor networking have opened up new opportunities in healthcare systems. The future will see the integration of the abundance of existing specialized medical technology with pervasive, wireless networks. They will co-exist with the installed infrastructure, augmenting data collection and real-time response. Examples of areas in which future medical systems can benefit the most from wireless sensor networks are in-home assistance, smart nursing homes, and clinical trial and research augmentation.
Enabling Technologies for Future Medical Devices:
As a result of the heterogeneity present in the system, communication between devices may occupy multiple bands and use different protocols. For example, motes use unlicensed bands for general telemetry or ISM equipment. Implanted medical devices may use a licensed band allocated for that purpose by the FCC. In order to avoid interference in the increasingly crowded unlicensed ISM band, biomedical devices may use the WMTS band (wireless medical telemetry services, at 608 MHz).
Real-time data acquisition and analysis: The rate of collection of data is higher in this type of network than in many environmental studies. Efficient communication and processing will be essential. Event ordering, time-stamping, synchronization, and quick response in emergency situations will all be required.
Reliability and robustness: Sensors and other devices must operate with enough reliability to yield high-confidence data suitable for medical diagnosis and treatment. Since the network will not be maintained in a controlled environment, devices must be robust.
New node architectures: The integration of different types of sensors, RFID tags, and back-channel long-haul networks may necessitate new and modular node architectures.
