Abstract

This research aims to design and evaluate the logging pattern suitable for Internet of things usage in medical fields with NETPIE, developed by National Electronics and Computer Technology Center (NECTEC), which reduces the distance issue in the patient monitoring applications and stores the health information of each period in details. The proposed logging mechanism uses the basic communication information without violating the data owner. There are three logging types including logging at things, logging at NETPIE and logging both. There are four issues to be checked by the system including new device, complete communication, complete communication with delay, and data lost. The evaluation result from 4 sensors on each patient; there are 30 patients; the data is sent every 250ms to the doctor computer at the hospital via NETPIE using each logging type. The results show that the logging mechanism can detect all new connections and delays. However, the lost and delay can be detected differently for each logging type. For logging at things only, the lost cannot be detected. For logging at NETPIE only, the lost-before-NETPIE cannot be detected. For logging at both, all issues can be detected. The storage for the logging data for logging at things is 0.4%, 0.2% for the logging at NETPIE and 0.61% for logging at both. Thus, the storage for the logging data is less than 1% of all communication data. However, the logging at both can affect the delay. There are 0.91% of data take the average travel time slightly larger than 1 second.
