A bloom filter is representation of data item indexes,
which achives small memory requirement
by allowing one-sided errors (false positive).
Because of such feature, it is often used for lookup in P2P networks;
in advance, each peer disserminates a bloom filter
representing indexes of the data items it owns.
Using the information in disserminated bloom filters as clue,
each query can find a short path to its destination.
In this paper, we propose an extension of bloom filter,
called a Deterministic Decay Bloom Filter(DDBF),
and a search method based on it.
While the standard bloom filter suffers performance degradation
caused by containing the information of too much data items
when its dissermination range is large,
the DDBF can circumvent such degradation
caused by containing the information according to the distance
between the filter holder and items holders, i.e.,
a DDBF contains the less information for faraway items
and much information for nearby items.
Then, we can reduce the amount of information aggregated by one peer,
and can avoid the increase of error rate.
We also show by simulation that our method can
achieves better lookup performance than than the existing one. |
