“…However, the initial scale-free topology is built using a centralized oracle, which does not provide support for reverting the topology after an attack is complete. Our own previous work, HITAP [26] (Hormone-Inspired Topology Adaptation Protection), similarly proposes a binary switch approach, but is fully decentralized and biologically inspired. HITAP uses the diffusion of an "alert hormone" through the nodes, to propagate the signal to switch between a superpeer and a flat topology, in response to targeted attacks against high-degree peers, and to switch back as the hormone level decays.…”

“…The Myconet protocol has a number of parameters, and we have chosen their settings based on values used in our previous work for ease of comparison [25,26,29]). The C n parameter controls the target number of inter-hyphal links that branching and immobile nodes maintain, and influences the level of resilience of the superpeer Myconet overlay to disruptive events.…”

“…In our experiments, we simulate denial-of-service attacks against the most important peers in the network as used in our previous work [26] (and similar to the attack described in [33]). During this attack, the k highest-degree peers are removed each cycle.…”

Unstructured superpeer overlays are an approach to peer-to-peer systems that enables collective organization and ensures the efficient participation and use of divers peers with heterogenous capabilities and resources. Such overlays are, however, vulnerable to failures and attacks that target the superpeers in an attempt to disrupt the overlay. In this paper, we present SODAP (Self-Organized Degree Adaptation Protection), a self-organized strategy for the self-protection of the overlay, based on the local adaptation of a peer's degree in response to disconnections, whether directly detected, or indirectly discovered with the assistance of neighbor peers. When network conditions deteriorate, the SODAP mechanism induces the creation of redundant connections to superpeers, which leads to the adjustment of the entire overlay to a topology that is more resilient to disconnection, while still allowing the system to continue exploiting heterogeneous peer capabilities. When network conditions improve, SODAP responds by reducing peer degrees to reduce redundancy and streamline the topology. We demonstrate this mechanism and evaluate its effectiveness as an extension to Myconet, a self-organized superpeer overlay for unstructured peer-to-peer networks.
