Complex Network Traffic Congestion Evacuation Strategy

There are a variety of networks in the real world. Our life is closely related to thenetwork. With the development of the society, the network scale grows explosively, thenetwork is easy to appear a series of problems, and a typical problem is the networkcongestion. Network congestion not only affects our life, but also hinders thedevelopment of social and economy. By changing the network topology structure tosolve the network congestion not only needs huge economic investment, but also notscientific and reality. On the other hand, we can abstract real network into concretecomplex network model, based on the network model, looking for a better trafficevacuation strategy to improve the efficiency of network transmission is a kind ofeconomic and convenient method. So, how to optimize the network traffic evacuationstrategy becomes an important topic in the field of complex networks. The research ofcomplex network traffic evacuation strategy can not only rich theory of complexnetwork, but also brings practical significance.On the basis of the static local routing strategy, by limiting the number of packetqueue and removing packets that stranded in the network for a long time, we get twoimproved network traffic evacuation strategies, through simulation and analysis, twooptimizations further increases the network critical packet generation rate, shorten thepacket transmission time. Simulation to get the packet distribution on the nodes ofnetwork explains the inner mechanism of improving the network transmissionefficiency by proposed optimization schemes. under the emergency that a nodeprocessing power reduces in the network, traffic dynamic model is established and theresult of the incident influence on the network traffic by simulation is analyzed, we putforward the packet preference Selection routing strategy to reduce the influence of theincident on network traffic, and by changing the parameters of policy value, we get theoptimal strategy plan.
