%X Localization technology plays an important role in wireless sensor networks,several Range-free localization algorithms are analyzed and Localization Based on Received Signal Strength Indicator(LBRSSI) is presented.LBRSSI uses rings generated by comparing received signal strength to determine node's location and additional angle threshold to suit irregular wireless signal.Location precision affected by some system parameters is studied,the results are that larger radio propagation irregularity can lead to small localization precision,increasing anchor nodes number can get localization precision better,increasing the anchor nodes' distance can partially improve localization precision.
