Abstract :
In this paper indoor wireless Infrared (IR) technology for healthcare monitoring is studied. Monitoring provides a continuous and reliable vital sign measurement to secure patient staying in the hospital. Considering that patient moving is inevitable, we focus on a mobile IR channel based on diffuse propagation. A model of mobile channel is developed through the study of statistical distributions of channel gain state for OOK modulation. We consider two mobility schemes for the transmitter which is coupled to the monitoring system: one in 2 dimensions (2D) for (x,y) mobility and another in 3D for (x,y,z) mobility. From statistical analysis, the outage probability is calculated in order to evaluate the performance for different data rates and for different average transmitted power before concluding on the reliability of diffuse mobile monitoring.
