A method and system for monitoring assets using radio frequency tags is provided
that includes a plurality of primary tags. Each primary tag stores an identification
of each linked tag associated with the primary tag. The primary tag receives a
polling event and transmits a query message for linked tags within an operational
range of the primary tag. Each linked tag receiving the query message transmits
a response message that includes an identification of the linked tag. The primary
tag receives the response messages and compares the identifications in the response
messages to the identifications stored for each linked tag. Based on the comparison,
the primary tag determines a monitored asset status.
