1. Apparatus for metasearching on a wireless sensor network, comprising:

  • a plurality of spatially distributed sensor nodes, comprising a plurality of motes that monitor physical and environmental conditions at a plurality of locations,each mote of said plurality of motes comprising;

    at least one sensor, which collects physical and environmental data, a mote server device, and a mote-transceiver,said each mote of said plurality of motes communicating with at least one other mote of said plurality of motes;

    a gateway node, comprising a gateway transceiver and a gateway server device, which comprises a metasearch engine,said metasearch engine communicating with at least two motes of said plurality of motes directly or via said at least one other mote of said plurality of motes or combination thereof;

    a client device, comprising a client transceiver,said client device communicating with said metasearch engine;

    said metasearch engine receiving a request from said client device, activated by said request executed on said client device, for said metasearch engine to request said metasearch engine to send a plurality of search queries to said at least two motes of said plurality of motes,said metasearch engine sending said plurality of search queries to said at least two motes of said plurality of motes,said metasearch engine receiving search results from said at least two motes of said plurality of motes in response to said plurality of search queries sent to said at least two motes of said plurality of motes,said metasearch engine grouping and sorting said search results into a plurality of groups comprising a plurality of physical and environmental data lists, according to said plurality of search queries,said metasearch engine incorporating said grouped and sorted search results, comprising said plurality of groups comprising said plurality of physical and environmental data lists, into a response for communicating to said client device,said metasearch engine communicating said response to said client device.
