Abstract

bio-inspired diffusion P2P self-organization self-protection
We present a bio-inspired mechanism that allows a peer-to-peer overlay network to adapt its topology in response to attacks that try to disrupt the overlay by targeting high-degree nodes. Our strategy is based on the diffusion of an “alert hormone” through the overlay network, in response to node failures. A high level of hormone concentration in a node induce that node to switch protocol. That leads to a self-organized modification of the entire overlay from a superpeer, scale-free layout, to a flatter network that is much less vulnerable to targeted attacks. As the hormone is metabolized with time, nodes switch back to the original protocol and reconstruct a superpeer overlay. We demonstrate and evaluate this mechanism on top of the peer-to-peer Myconet overlay, which is itself self-organized and bio-inspired.
