NS3-based simulation system in heterogeneous wireless network

The development of wireless technologies shows a trend to heterogeneous wireless network (HWN), which attracts extensive attention on the research. Compared with a real network environment, a simulation system not only reduces cost, but also provides reliable and quantitative basis. This paper presents the design and implementation of our simulation system in HWN based on NS3 (Network Simulator 3), and two experiments we conducted in the system.
