Summary:How to obtain location information of an unknown node precisely is a key problem of locating service under ubiquitous computing environment. The paper proposes and proves the theorem of spatial location unit distribution model according to the analysis of the location error produced during location using the polygon location method in the three-dimensional space. On this basis, the location unit selection (LUS) algorithm is proposed by improving on the traditional polygon location algorithm. The simulation results indicate that the location unit distribution model theorem and the LUS algorithm can meet the requirements of a ubiquitous terminalpsilas real-time location and possess a preferable precision in location.
