Abstract:
In order to improve the system throughput of IEEE 802.11n under delay constraint, the average data quantity of one transmission with aggregation under non-ideal channel condition(when transmission error exists)is derived. The calculating formula of saturation throughput of distributed coordination function(DCF)system in non-ideal channel condition is obtained by inlaying the average data quantity into the mathematical expression of saturation throughput in Markov model which describes the DCF system in ideal channel condition. Analysis is presented on the average delay of system and each backoff stage of DCF with aggregation scheme to transform the delay constraint to the limit of average delay. To maximize the saturation throughput, the packet size and aggregation number are dynamically adjusted according to the variable channel conditions under the limit of average delay. The simulation results show that the system throughput from the adjusting algorithm is obviously higher than that from fixed packet size and aggregation number scheme.
