Abstract
A method and system for dividing a set of tagged items into subsets. Each tagged item is tagged with a passive RFID tag. A RFID reader is instructed to poll the RFID tags of all tagged items in a specified region having fixed boundaries to generate information including, for each tagged item, a spatial location of each tagged item and a list of all other tagged items in the region which are adjacent to each tagged item. The region is split into non-overlapping subregions. For each subregion, a central tagged item having more adjacent tagged items in each subregion than any other tagged item in each subregion is determined, utilizing the generated information. A virtual boundary is outlined around the central tagged item to enclose the central tagged item and a portion of the tagged items in each subregion which are adjacent to the central tagged item.
