Estimation of ZigBee´s RSSI fluctuated by crowd behavior in indoor space

Crowd behavior research gets more and more important, because crowd has a matter of common livelihood. However, estimation of looking at crowd behavior in a large field of view hasn´t had adequate study done. To solve above problem, this paper presents the fluctuation of ZigBee´s Received Signal Strength Indicator (RSSI) effected crowd behavior indoor space and the possibility of estimation of crowd behavior using ZigBee´s RSSI from the macro standpoint. To begin with, we define the crowd behavior in indoor space. Next, we measure ZigBee´s RSSI in those of environment. Finally, according to the given result about environment, we analyze time-series of RSSI, including the possibility of knowledge for crowd behavior from ZigBee´s RSSI.
