A wireless parameter-sensing node in a network thereof, the parameter-sensing node includes: sensors to sample values of parameters, respectively; a memory; a collection engine configured to: selectively collect data representing at least some of the sampled values, respectively; and store the collected data in the memory; an omega engine configured to: retrieve selected portions of the collected data from the memory; and send the selected portions to a remote host; wherein at least one of the collection, the storage, the retrieval and the sending are performable according to one or more reconfigurable collection-control criteria, one or more reconfigurable storage-control criteria, one or more reconfigurable retrieval-control criteria and one or more reconfigurable reporting-control criteria, respectively, stored in the memory. The parameter-sensing node and the remote host relate, e.g., as a taskee-client and a taskor-server, respectively.
