Asymmetry in Repairing and Infection: The Case of a Self-repair Network

摘要

A self-repair network is a model consisting of autonomous nodes capable of repairing connected nodes. Self-repairing by mutual repair involves the "double-edged sword" problem where repairing could cause adverse effects when done by abnormal nodes. Although self repair (as opposed to mutual repair) is not susceptible to this problem because an abnormal node always repairs itself, the possibility of normal nodes repairing abnormal nodes is lost. This note compares these two types of repair: mutual and self for a self-repair network with infections. With this extended model, abnormal nodes can spread not only by repair failures but also by infections.
