Abstract :
Real-time patient monitoring is critical to early detection of clinical patient deterioration in general hospital wards. A key challenge in such applications is to reliably deliver sensor data from mobile patients. We present an empirical analysis on the reliability of data collection from wireless pulse oximeters attached to users. We observe that most packet loss occur from mobile users to their first-hop relays. Based on this insight we developed the dynamic relay association protocol (DRAP), a simple and effective mechanism for dynamically discovering the right relays to be used for forwarding data from mobile users.
