To get high precision of localization with radio irregularity in WSN(wireless sensor network),a multi-node localization method based on RSSI is proposed.The position is acquired approximately to predict the angle of each antenna,then the RSSI based on the angle is processed,and the positions of anchor node is used to calculate the position of the node.The experiments show that the average location error is improved from 40% to less than 10%.

Key words: wireless sensor network;localization;radio irregularity;RSSI;anchor node
