Link layer traffic and behavior in congested WLANs

Author Name : Vikram Singh

ABSTRACT: In a congested network, the client faces a lot of problem (overhead) to transmit a single frame of useful data. So, the efficiency is reduced. This problem causes a lot of packets to be lost. When packets are lost, the client misinterprets the actual reason for it (whether it was congestion or the error in transmission). Client may even perform Hand-off which may be purely unnecessary, thereby increasing the overhead. The main components which constitute the unwanted traffic are the management frames and the control frames. So, there is a need to reduce the sending and receiving of such frames to an extent that the performance doesn’t pay the price.
