Recent work has shown that intelligent neighbor selection during construction
can significantly enhance the performance of peer-to-peer overlay networks.
While its impact on performance has been recognized, few have examined the
impact of neighbor selection on network resilience. In this paper,
we study the impact with a generalized cost model for overlay construction that
takes into consideration different types of heterogeneity, such as node
capacity and network proximity.
Our simulation results show that the resulting performance improvement
comes at the cost of static resilience against targeted attacks.
