Patent ID: 8437773

Claim:
A method for use in a location based system having a hierarchical zonal structure defined, at least in part, by a first nodal transmitting device located in a first zonal position in said hierarchical zonal structure and a second nodal transmitting device located at a second zonal position in said hierarchical zonal structure, said first zonal position being different than said second zonal position, the method comprising: obtaining with said first nodal transmitting device one or more signals representing information associated with an item of interest located at a specified location, transmitting with said first nodal transmitting device to said second nodal transmitting device one or more signals representing part of said information associated with said item of interest, wherein within said location based system said first zonal position and said second zonal position are differentiated and propagation of said information and said part of said information is selectively controlled based, at least in part, on at least one of a spatial restriction parameter associated with said specified location, and a temporal restriction parameter associated with the hierarchical zonal structure.
