%X Getting location information of an unknown mobile node is a key point of locating service in the ubiquitous computing environment.The errors due to locating an triangular area was studied in the 2-D space as a pervasive computing environment.And the theorem of a locating unit deployment(LUD) was presented.Based on the finding,a new physical property parameter of coverage,coverage base,was defined and introduced for the first time.And,the deployment issue between locating units was also studied,as a result,t...
