IEEE 802.11 wireless LANs (WLANs) employing CSMA/CA has been widely and densely deployed, and its demand is still growing.
In the wireless LAN, the increase of traffic demand brings severe contention to obtain a transmission opportunity among multiple basic service sets , and it brings frequent collisions of frame transmission, and then subsequently leads to frame loss.
However, in general, the transmitter hardly knows why its frame is lost, in other words, whether SNR is insufficient or frame is collided.
So, it is important to analyze and/or know the reason of frame loss to take a suitable action to avoid frame loss and to improve communication quality. |
