%X Node localization is a hotspot in international research of Wireless Sensor Network (WSN). Location error cumulate is a key problem to deal with in node localization. Error cumulate could be restrained effectively by using Weighted Least Square Estimates (WLSE). How to apply WLSE to node localization algorithm and choose proper weight coefficient to reduce location error are introduced. Simulations studies show that WLSE perform well by restrain the error cumulate and improve location precision.
