%X Localization is an emerging subject in the filed of Wireless Sensors Networks(WSNs).This paper describes a hybrid localization approach combinning TOA(Time of Arrival) ranging with DV_distance localization algorithm based on Zigbee networks.The main principle of hybrid scheme is using DV_distance to get the culmulative distance with correction,after ranging the neighbor-nodes distance by TOA.The TOA ranging based on MAC-layer protocal of Zigbee can get a perfect result with no additional hardwares.This approach shows perfect precision,less affected by the proportion of anchor nodes,which is quite suitable for localization in large scale WSNs.
