A first communication device comprising memory in which data is stored may receive a request packet from a second communication device, measure received signal strength for the request packet, and determine whether to perform the requested search of the data stored in the memory based on the received signal strength and the power at which the request packet was transmitted. The search request packet may comprise a request to search the data stored in the memory, and a transmit power field that indicates a power at which the request packet was transmitted. The determining may be based on a result of a comparison between the received signal strength and a threshold and/or based on a comparison of a relative power and a threshold. The relative power may be calculated utilizing the received signal strength and the power at which the packet was transmitted. |
