802.11 slot time propagation delay

By Administrator

For the IEEE 802.11 DCF basic access mechanism, a successful transmission includes the time for the physical and MAC headers (), payload (), SIFS (), DIFS (), and an acknowledgment from the intended receiver station, considering the propagation delay: where and are the propagation delay and the longest packet payload involved in the collision ...

(CSMA/CA) protocol according to IEEE 802.11 standard, approved in June 1997, for Wireless Local Area Networks. The model has been developed using the simulation tool SES/Workbench. Our purpose is to analyze the access protocol performance in terms of available throughput, access delay and packet dropping. The evaluation has been done to make a
