A new localization algorithm was proposed to enhance positional accuracy of ZigBee from improving distribution of beacon nodes. In this algorithm, beacon nodes were distributed as regular hexagon, with preferred appropriate beacon nodes in location calculation. RSSI was adopted as the distance reference. Moreover, Multimetering Averaging Method was used to reduce the impact of Gauss noise on RSSI.
