Method and apparatus for adaptive searching of distributed datasets

摘要

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.

1. A method comprising:
in a first communication device comprising memory in which data is stored:
receiving a request packet from a second communication device, wherein said request packet comprises:
a request to search said data stored in said memory; anda transmit power field that indicates a power at which said request packet was transmitted;measuring a received signal strength for said request packet;determining whether to perform said search of said data stored in said memory based on said received signal strength and said power at which said request packet was transmitted;performing said search by comparing a search token to said data stored in said memory; andgenerating a search score that indicates one or more of:
the number of matches and/or partial matches of said search token found in said data stored in said memory; andthe location of matches and/or partial matches of said search token found in said data stored in said memory.
