Packet Transport on Scale-Free Networks
We introduce a model of information packet transport on networks in which the packets are posted by a given rate and move in parallel according to a local search algorithm. By performing a number of simulations we investigate the major kinetic properties of the transport as a function of the network geometry, the packet input rate and the buffer size. We find long-range correlations in the powe...
متن کاملRobustness of the avalanche dynamics in data-packet transport on scale-free networks.
We study the avalanche dynamics in the data-packet transport on scale-free networks through a simple model. In the model, each vertex is assigned a capacity proportional to the load with the proportionality constant 1+a . When the system is perturbed by a single vertex removal, the load of each vertex is redistributed, followed by subsequent failures of overloaded vertices. The avalanche size d...
متن کاملPacket transport and load distribution in scale-free network models
In scale-free networks, the degree distribution follows a power law with the exponent . Many model networks exist which reproduce the scale-free nature of the real-world networks. In most of these models, the value of is continuously tunable, thus is not universal. We study a problem of data packet transport in scale-free networks and de/ne load at each vertex as the accumulated total number of...
متن کاملAnomalous transport in scale-free networks.
To study transport properties of scale-free and Erdos-Rényi networks, we analyze the conductance G between two arbitrarily chosen nodes of random scale-free networks with degree distribution P(k)-k(-lambda) in which all links have unit resistance. We predict a broad range of values of G, with a power-law tail distribution phi(SF)(G)-G(-g(G)), where g(G)=2lambda-1, and confirm our predictions by...
متن کاملSandpile on scale-free networks.
We investigate the avalanche dynamics of the Bak-Tang-Wiesenfeld sandpile model on scale-free (SF) networks, where the threshold height of each node is distributed heterogeneously, given as its own degree. We find that the avalanche size distribution follows a power law with an exponent tau. Applying the theory of the multiplicative branching process, we obtain the exponent tau and the dynamic ...
