Abstract
A host and a communicatively linked paired tag can be identified. The tag can be associated with a tracked entity. The tag can be a low power computing device which can provide a location of a tracked entity to the host. An out of range condition can be detected. The condition can result in communication between the host and the tag being temporarily interrupted. A last location of the tag can be established. A set of hosts proximate to the last location can be determined. The set of hosts can be queried to determine if the hosts have received an advertisement message from the tag. Each of the set of hosts can be linked to a different paired tag. A notification can be conveyed to the host when the set of hosts receives the message from the paired tag. The notification can include a new location of the paired tag.
