Summary of Experimental Results on Accurate Wireless Sensing System for a Group of Exercisers Spread in an Outdoor Ground

Towards the purposes of health care and injury/disease prevention for a group of exercisers in an outdoor ground, we have been developing a system named ʠ AccuWiSe (Accurate Wireless Sensing). ʡAccuWiSe employs a novel multi-hop networking protocol based on flooding/time division multiple access scheme, and just by putting vital sensor nodes to exercisers, it can collect vital data at a data collection node without any relaying nodes, such as heart rate, volume oxygen, body surface temperature/humidity and air temperature/humidity. We have so far successfully finished two demonstration experiments of AccuWiSe involving 50 subjects on the 6th of March and the 9th of August, 2019. In this paper, we summarize the experimental results and discuss solutions for the problems encountered in the experiments.
