Abstract: The paper presents original results from research that analyses words that are used by the readers of given text to describe the key message in the entire text. Those readers’ words are then lemmatized and compared to lemmatized words from the original main text. The research reveals that for texts with deeper meaning are used surprisingly and also significantly such words by the readers that cannot be found in the entire original text. The percentage of such words increases when forced to express the key message using less words.

A PERFORMANCE OF MAC LAYER OVER ERROR-PRONE CHANNEL IN THE IEEE 802.11AC
Published In: 2ND INTERNATIONAL CONFERENCE ON ADVANCES IN COMPUTING, ELECTRONICS AND COMMUNICATION
Author(s): HA CHEOL LEE
Abstract: A MAC (Medium Access Control) layer throughput is evaluated over error-prone channel in the IEEE 802.11ac-based wireless LAN. In this evaluation, DCF (Distributed Coordination Function) protocol and A-MPDU (MAC Protocol Data Unit Aggregation) scheme are used. Using theoretical analysis method, the MAC saturation throughput is evaluated with the PER (Packet Error Rate) on the condition that the number of station, transmission probability, the number of parallel beams and the number of frames in each A-MPDU are variables. When the PER is 10-2 and the number of aggregated MPDUs in each A-MPDU is 20, it is identified that the MAC layer throughput of IEEE 802.11ac can be maximally attained up to a 92.8% of physical transmission rate in this evaluation.
