Integrating legacy medical data sensors in a wireless network infrastucture.

In the process of developing a wireless networking solution to provide effective field-deployable communications and telemetry support for rescuers during major natural disasters, we are faced with the task of interfacing the multitude of medical and other legacy data collection sensors to the network grid. In this paper, we detail a number of solutions, with particular attention given to the issue of data security. The chosen implementation allows for sensor control and management from remote network locations, while the sensors can wirelessly transmit their data to nearby network nodes securely, utilizing the latest commercially available cryptography solutions. Initial testing validates the design choices, while the network-enabled sensors are being integrated in the overall wireless network security framework.

A novel communications network for the provision of medical care in disaster and emergency situations.

We have designed and developed a novel data communications network targeted at the provision of Emergency Medical Care in disaster situations over wide areas. The network nodes can transmit essential biosignals and in addition, support video and diagnostic quality sound (auscultation) broadcasting for teleconsultation purposes, by using a variety of wireless transports. The medical data acquisition stations are networked dynamically and on demand, with no requirement for an existing communications infrastructure at the disaster sites. The network design allows for limited transmitting station mobility and support for software-based Voice over IP during station roaming. Initial test results, following the hardware and software integration, indicate that the chosen network design meets specifications, and a full-scale field test, utilizing a large number of wireless stations operating under realistic conditions is to take place.
