Abstract:

An efficient weakening community structure strategy (WCS) by adding links to the existing networks was propose,which could enhance Internet transmission performance.Internet topology reconstruction could be realized by WCS strategy,because lightpaths that represent logical links between nodes could achieve the same high performance as physical links by means of optically bypassing intermediate nodes.The performance of the proposed strategy was investigated in pseudo random networks with community structure scale-free network with community structure and Internet,topology respectively,for both local routing strategy and global shortest-path routing strategy.The experimental results show that the traffic capacity of networks and the average shortest path are considerably improved by adding a few links among communities.

Key words: complex network, community structure, information transfer, modularity
