Title: Firewalks: Discovery Mechanism for Non-Replicable Reusable Resources
Author(s): Georgios Exarchakos, Nick Antonopoulos, Kan Zhang
Keywords: Peer-to-peer, adaptive search, non-replicable resources
Abstract: P2P Networks are traditionally used for file sharing, but have recently attracted attention for non-replicable reusable and mobile resource sharing. Existing blind search mechanisms for random directed graphs appear to have weak performance since they cannot cope with the dynamic behaviour of these resources. Firewalks is a blind search technique based on which queries hop from node to node using its most recently created link. This may ease the access to recently moved resources (from providers to requestors) and discovered providers. A number of experiments indicated that this technique has better and more stable performance without significant extra messages and manages to preserve the topology of the overlay in contrast to flooding and walkers.
