Firstly, a dynamic routing trust model based on trust relationship and routing behaviors is brought forward. The model not only supports trust network connection, but also gives a comprehensive assessment to the network security and efficiency affected by router access according to routers' interactive behaviors...
'Robust yet fragile (RYF)' is a major feature of Internet survivability. The cascading failure, which is caused by attacks or configuration mistakes, is one of the most serious incidents impact on the network survivability. Taking aim at this incident, this paper proposes a simple 'load-capacity' model based on the 'self-organized criticality' and the 'highly optimized tolerance' theories in complex...
