摘要：

This paper investigates the Hidden-node phenomenon (HN) that arises in IEEE 802.11 wireless networks. HN can cause many performance problems, including throughput degradation, unfair throughput distribution among flows, and throughput instability. Previous investigations mostly focus on indirect methods to alleviate these performance problems rather than direct elimination of HN. Such an approach may solve one but not all of these problems. This paper identifies the fundamental conditions leading to HN, and devises a Hidden-node-Free Design (HFD) to completely remove HN. Also, we further improve HFD to reduce Exposed-node problem while keeping the network free of HN.
