Definition, design and priority management of a cognitive radio driven hospital: CogMed

Wireless is becoming more and more common in the healthcare system in near future. These may cause issues such as EMI effects on the operating devices, shortage of medical band. To handle these issues in a proper manner, a hospital system has to be designed carefully. Therefore, in this article we propose system definition and design of a cognitive radio enabled hospital system known as CogMed. First we describe the shortcomings of recent wireless healthcare facility by critically analyzing the contemporary literatures on cognitive radio network centric healthcare facility. Then we propose a fully opportunistic network based hospital system architecture where dynamic spectrum access (DSA) capable medical, non-medical and sensor devices are characterized based on a dynamic priority management mechanism. We prioritize the medical and non-medical device according to the urgency. We also proposed a priority based channel access mechanism which is based on IEEE 802.11.e standard. The proposed priority policy emphasized not only the devices, but also the application in wireless hospital.
