Abstract
Towards the world of Internet of Things, people utilize knowledge from sensor
streams in various kinds of smart applications including, but not limited to smart
medical information systems. The number of sensed devices is rapidly increasing
along with the amount of sensing data. Consequently, the bottleneck problem
at the local gateway has become a huge concern given the critical loss and delay
intolerant nature of medical data. Orthogonally to the existing solutions, we
propose sensor data prioritization mechanism to enhance the information quality
while utilizing resources using Value of Information (VoI) at the application
level. Our approach adopts signal processing techniques and information theory
related concepts to assess the VoI. We introduce basic yet convenient ways to
enhance the efficiency of medical information systems, not only when considering
the resource consumption, but also when performing updates, by selecting
appropriate delay for wearable sensors to send data at optimal VoI. Our analysis
shows some interesting results about the correlation and dependency of different
sensor signals, that we use for the value assesment. This preliminary analysis
could be an initiative for further investigation of VoI in medical data transmission
using more advanced methods.Towards the world of Internet of Things, people utilize knowledge from sensor
