An Efficient Curing Policy for Epidemics on Graphs
"... Abstract-We provide a dynamic policy for the rapid containment of a contagion process modeled as an SIS epidemic on a bounded degree undirected graph with n nodes. We show that if the budget r of curing resources available at each time is VðW Þ, where W is the CutWidth of the graph, and also of ord ..."

The effect of network topology on the spread of epidemics
- IN IEEE INFOCOM
, 2005
"... Many network phenomena are well modeled as spreads of epidemics through a network. Prominent examples include the spread of worms and email viruses, and, more generally, faults. Many types of information dissemination can also be modeled as spreads of epidemics. In this paper we address the question ..."

the question of what makes an epidemic either weak or potent. More precisely, we identify topological properties of the graph that determine the persistence of epidemics. In particular, we show that if the ratio of cure to infection rates is smaller than the spectral radius of the graph, then the mean epidemic
The role of the airline transportation network in the prediction and predictability of global epidemics.
- Proc. Natl Acad. Sci. USA 103,
, 2006
"... The systematic study of large-scale networks has unveiled the ubiquitous presence of connectivity patterns characterized by large-scale heterogeneities and unbounded statistical fluctuations. These features affect dramatically the behavior of the diffusion processes occurring on networks, determini ..."

stochasticity of disease transmission and traffic flows. To address these issues we define a set of quantitative measures able to characterize the level of heterogeneity and predictability of the epidemic pattern. These measures may be used for the analysis of containment policies and epidemic risk assessment
When is a network epidemic hard to eliminate?
"... We consider the propagation of a contagion process (“epidemic”) on a network and study the problem of dynamically allocating a fixed curing budget to the nodes of the graph, at each time instant. For bounded degree graphs, we provide a lower bound on the expected time to extinction under any such dy ..."

How to distribute antidote to control epidemics
"... Motivated by the control of epidemics on technological and social networks, we give a rigorous analysis of a variant of the contact process on a finite graph in which the cure rate is allowed to vary from one vertex to the next, and even to depend on the current state of the system. We think of the ..."

Efficient control of epidemics over random networks
, 2009
"... Motivated by the modeling of the spread of viruses or epidemics with coordination among agents, we introduce a new model generalizing both the basic contact model and the bootstrap percolation. We analyze this percolated threshold model when the underlying network is a random graph with fixed degree ..."

Using the Small-World Model to Improve Freenet Performance
, 2002
"... Efficient data retrieval in a peer-to-peer system like Freenet is a challenging problem. In this paper we study the impact of cache replacement policy on the performance of Freenet. We find that, with Freenet's LRU cache replacement, there is a steep reduction in the hit ratio with increasing ..."

Epidemics in networks with nodal selfinfection and the epidemic threshold,” Phys
- Rev. E
, 2012
"... Since the Susceptible-Infected-Susceptible (SIS) epidemic threshold is not precisely defined in spite of its practical importance, the classical SIS epidemic process has been generalized to the ε−SIS model, where a node possesses a self-infection rate ε, in addition to a link infection rate β and a ..."
