Discovery of objects in wireless environments

摘要

An object discovery capability is provided to enable discovery of objects in a wireless environment, which may include discovering objects available from a set of wireless nodes in a wireless environment. The discovery of objects available from a set of wireless nodes may include a determination as to whether a particular object is available from the set of wireless nodes, identification of the wireless node or nodes from which a particular object is available, or the like. The object discovery capability may leverage physical features of the wireless medium (namely the additive nature of wireless signals in a Hertzian broadcast channel) in combination with set reconciliation techniques (e.g., using data encoding structures, such as Bloom filters, with information at the physical layer or one or more other layers) in order to enable discovery of objects available from a set of wireless nodes in a wireless environment.

主权项

1. An apparatus for discovering objects available from a set of wireless nodes, the apparatus comprising:
a processor and a memory communicatively connected to the processor, the processor configured to:
receive a sequence of combined wireless signals, the combined wireless signals being respective wireless combinations of wireless signals of respective wireless signal sequences transmitted by the wireless nodes, the wireless signal sequences of the wireless nodes being representative of respective local object data structures of the wireless nodes, the local object data structures of the wireless nodes being indicative of respective sets of objects available from the wireless nodes; andgenerate a combined object data structure based on the sequence of combined wireless signals, the combined object data structure being indicative of objects available from the set of wireless nodes.
