This paper is proposed a range-free localization algorithm in WSN technology. Effective use some useful information for localization algorithm during sensor node deploy process, to avoid distance-based localization algorithm when in complex environments ranging difficulties, while the same time, avoid the extensive use GPS node of anchor-free localization algorithm with cost Consideration. And the experiment results show that this method is available and efficient localization algorithm. Wireless sensor network is generally a close, low complexity, low power, low cost and low-bandwidth wireless communication network.
