Federating mote-associated index data

A method comprising:

• creating one or more administered content indexes for a set of motes;
• obtaining at least a part of the one or more administered content indexes of the set of motes, the obtaining comprising:
• obtaining first sensing, control, and routing/spatial indexes for a first subset of the set of motes associated with a first domain, and
• obtaining second sensing, control, and routing/spatial indexes for a second subset of the set of motes associated with a second domain, the second domain being different from the first domain;
• and
• creating a federated index from at least the part of the one or more administered content indexes, the federated index comprising federated sensing, control, and routing/spatial indexes for the first subset of the set of motes associated with the first domain and the second subset of the set of motes associated with the second domain,
• wherein said creating further comprises:
• determining a mote-network address of a first mote;
• determining a listing of mote-network addresses of other motes directly accessible from the first mote by direct radio transmission;
• determining a listing of spatial orientations of the other motes relative to the first mote and spatial reference locations for the other motes that are directly accessible from the first mote;
• and
• associating, with the mote-network address of the first mote, the listing of mote-network addresses of the other motes directly accessible from the first mote and the listing of the spatial orientations of the other motes relative to the first mote and the spatial reference locations for the other motes that are directly accessible from the first mote.
