Abstract: Targeted at heterogeneous network, the environment of topology is complex, changeable, unbalanced load, etc. Traditional cognition of the network is no longer meeting the needs of its performance enhancing. So an important prerequisite for heterogeneous network performance enhancing is analyzing parameters reasonably. In the case of no object model and prior knowledge, this paper uses the ns2 to simulate a large number of heterogeneous network environments with the bottleneck link and different state, then creates two new parameters. It uses the lattice close-degree method to analyse the correlation of each parameter depthly. The new parameters have high correlation and response the current network performance effectively, providing a reliable basis for future work on split-link connection of heterogeneous network performance enhancement.
