Hidden terminal problem in wireless lan
WebA carrier sense multiple access with collision avoidance (CSMA/CA) is an access protocol of wireless LAN (WLAN). When the carrier sensing is missed, the WLAN systems simultaneously access the channel and then packet collision occurs. It is a hidden terminal problem. In this paper, the recognition of the hidden terminal problem is performed by … WebThe popular Wireless Fidelity (Wi-Fi) LAN standard (more accurately, the IEEE [802.11] ... To understand the hidden terminal problem, consider the two wireless laptops and AP shown in Figure 3.12. (The problem does not only occur with …
