In the research of wireless sensor network, it is important to estimate the location nodes. In this paper, we analyze a problem of the position estimate technique that previously proposed. Then propose the additional method that can solve it. With this method, we can find the positions of nodes easily because we use information that nodes have. And we can make a map for all the nodes because we can measure a relative position for an node whose position is not known based on anchor nodes whose positions are already known and then we can confirm whether nodes are placed appropriately. We confirmed that we could locate positions of all nodes, estimated node positions had average 4~7% error through verifying the proposed method.
