Abstract: To apply wireless sensor networks to stereoscopic environments such as outer-space and deep oceans, three dimensional localizations are required. Approximate Point in Sphere (APIS) arithmetic based on calculating intersections of spheres was brought forward. Both principles and practice of APIS were discussed. APIS-based algorithm was then simulated with Visual C. Results indicate in the space of 100*100*100 with 55 randomly scattered anchor nodes, locations of 98% of nodes could be calculated. The average errors in relative remain as small as 60%. In conclusion, APIS algorithm is an effective approach to determine the locations of nodes of a sensor network in 3d space.
