Abstract(in English) | Interworking among heterogeneous wireless networks across licensed and unlicensed bands has gained much attention to support the surge in mobile traffic. In unlicensed bands, the dominant wireless network application is wireless LAN (LAN) where frequency resources are shared based on carrier sense multiple access with collision avoidance (CSMA/CA) mechanism. When the mobile traffic starts to overwhelm the wireless resources, the throughput of some users will be significantly degraded by the hidden and exposed terminal problems created by radio environment asymmetry around the transmitter and the receiver. In order to alleviate this problem, we present a channel access acquisition control scheme for wireless LANs with the assist of licensed band. In this paper, we evaluate our proposed scheme through computer simulations, and show that our scheme improves the user throughput by twice even when there exist uncontrollable APs. |
