Priority Aware Cognitive Radio Driven Hospital System

Abstract

Wireless communication technology is the prime attribute to improve mobility, flexibility and reliability for hospital information system. However, due to the growth of wireless devices in near future, healthcare services may face challenges on medical spectrum scarcity, electromagnetic interference to bio-medical devices and medical data transmission reliability. To dimi nish these issues cognitive radio (CR) can be improvised and fine-tuned the wireless healthcare service system. However, contemporary research on CR driven healthcare has shown limited guidelines for priority policy and network model for hospital. Thus, the main objective of this research is to design a CR based system for healthcare services where all of the hospital devices are CR enabled and categorized as per the activity. An intelligent dynamic priority enabled queuing management based hospital traffic transmission mechanism is then introduced in the proposed system. The proposed priority mechanism intelligently determines the critical level of medical management by computing weight of hospital traffics considering hospital location and device priority. The proposed priority mechanism intelligently determines the critical level of hospital data and decreases the rate of packet drop. Finally, simulation results show that the critical emergency medical traffic obligates very low drop rate, queuing time and network delay comparing to other hospital devices. The proposed system transmission is also shown to outperform the other well-known methods for data transmission system.
