LinkNet: A New Approach for Searching in a Large Peer-to-Peer System

This paper presents a new scalable distributed data structure LinkNet for searching in a large Peer-to-Peer system.In LinkNet,all elements are stored in a sorted doubly linked list,and one node stores many elements.LinkNet uses virtual links to decrease storage cost and speed search.In an N nodes M elements network,the expected total space this data structure takes is(O(M),) and when M is big enough,the search operation takes expected O(logN) messages among nodes.
