1. A system, comprising:
- a structure; and
a plurality of radio frequency identification devices (RFIDs) supported by the structure, wherein each of the plurality of RFIDs;
queries one or more proximate RFIDs to determine initial relative location information for the one or more proximate RFIDs;
stores the initial relative location information in a memory;
in response to a predetermined event, queries the one or more proximate RFIDs to determine post-event relative location information for the one or more proximate RFIDs; and
forwards the initial relative location information and the post-event relative location information to a remote processing device,wherein the remote processing device analyzes the post-event relative location information to determine whether the structure has experienced a damage event.

Abstract
A plurality of RFIDs is installed on aircraft or other structure. The RFIDs can query one another upon original installation and in response to predetermined event detection, and determine their relative locations within a mesh. The determined location data and other information are stored within the respect memories of the RFIDs. The stored data can be later accessed and used in analyzing damage or structural failure of the aircraft. Corrective measures are thus expedited because before-and-after structural comparisons can be readily made, with or without reference to original engineering data for the aircraft.

9. An aircraft including one or more structural elements, the aircraft further comprising:
a plurality of radio frequency identification devices (RFIDs) supported at respective locations by the one or more structural elements, the plurality of RFIDs defining respective nodes of a mesh, wherein at least a first RFID wherein each of the plurality of RFIDs; queries one or more proximate RFIDs to determine initial relative location information for one or more proximate RFIDs; stores the initial relative location information in a memory; in response to a predetermined event, queries the one or more proximate RFIDs to determine post-event relative location information for the one or more proximate RFIDs; and forwards the initial relative location information and the post-event relative location information to a remote processing device, wherein the remote processing device analyzes the post-event relative location information to determine whether the structure has experienced a damage event. - View Dependent Claims (10, 11, 12, 13, 14)
