Efficient Person Search Mechanism in Peer-to-Peer Networks在點對點網絡有效尋找人的機制

总结: A structured overlay using in Pastry is efficient to search for unique items and is applied in our study. However, since all items are treated equally in structured overlays, the search time for popular people (such as the ones in the hot list) cannot be fast based on Pastry. We therefore propose a scheme which makes use of the user's hot list to form the routing table for the search phase, leading to faster search time for the ones a user calls often.

Furthermore, by intelligently assigning nodeIDs to peers, peers of the same domain can be close to each other in the overlay search graph. Due to access locality within a domain, the search goes to a domain first before the person is located. This greatly reduces search time. Simulation shows that the search time for our approach is much faster than the traditional Pastry (by as much as 50%).
