Influence on Asymmetric Space-link Performance of Vegas Algorithm
Shengbo Hu · Guizhou kexue · 2011
TCP performance of asymmetric space link is very important to spatial network.Based on NS2,the spatial network TCP scenario is built.After several TCP congestion control algorithms are compared,the Vegas algorithm for asymmetrical space-link performance is focused.Simulation results based on NS2 show that Vegas algorithm window threshold α and β can increase the throughput and the corresponding window sizes will become larger.The number of packets δ in the buffer of Vegas algorithm estimates affects the size of the window,and throughput is biggest while δ is selected the default value.
