A proposal of QoE based self-organized wireless system considering the measurement results in a major hospital

In this paper, we propose a Quality of Experience based autonomously distributed wireless system for medical and disaster situation. The radio resource assignment and topology are dynamically controlled based on QoE of each application. First of all, we show a situation of 2.4 GHz wireless system environment in a major hospital, and raise some issues of spectrum usage in medical area from the measurement results. The results indicate possible technologies for more efficient spectrum usage with considering application quality. After discussing these aspects, we show the concept of our proposed self-organized wireless system for solving the issues.
