Research of the BA Network Information Transmitting Based on the LAN Selection Strategy

Information transmitting has been a very important research field of complex network and lots of researchers have been contributing to it for years to help improve the transmitting efficiency and the network´s loading capacity, and build of the information transmitting mechanisms. But most of them are based on the global information of the topology architecture, which turns out to be quite difficult to obtain when the network becomes larger. In view of that situation, authors propose an information transmitting model based on the Local Selection Strategy. In this model, the source nodes where the information package locates are based on the topology information of its neighbor nodes, and will select a node as a target to transmit information until the packet reaches the target nodes. In this paper, authors study the efficiency of the information transmitting of the model in the network of BA. It is figured out in the final results, with the average degree of the network becomes bigger, the transmitting efficiency improves, while the speed of improvement slows down. In that case, elevation of the transmitting efficiency with increasing the scale of network is limited.
