“…Regarding UDP-like traffic, the performance of IEEE 802.11 (taking into account the aggregation schemes) has been investigated in dozens of papers over the years. For example, in [23][24][25][26][27][28][29][30][31][32][33][34][35] the Throughput and Delay performance of the A-MSDU, A-MPDU and Two-Level aggregation schemes are investigated. Several papers assume an error-free channel with no collisions, several papers assume an error-prone channel and others also assume collisions.…”

This paper suggests a new model for the transmission of Transmission Control Protocol (TCP) traffic over IEEE 802.11 using the new features of IEEE 802.11ac . The paper examines a first step in this direction and as such we first consider a single TCP connection, which is typical in a home environment. We show that when the IEEE 802.11ac MAC is aware of QoS TCP traffic, using Reverse Direction improves the TCP Goodput in tens of percentages compared to the traditional contention based channel access. In an error-free channel this improvement is 20% while in an errorprone channel the improvement reaches 60%, also using blind retransmission of frames. In our operation modes we also assume the use in Two-Level aggregation scheme, the Automatic Repeat-Request (ARQ) protocol of the IEEE 802.11ac MAC layer and also assume the data rates and the four Access Categories defined in this standard.

“…But 802.11n transmitters also accept Block ACKs which confirm receipt of multiple unicast frames. For example, instead of sending 9 legacy ACKs to confirm frames 1 through 8 and 10, an 802.11n receiver can say the same thing with just one Block ACK [10].…”

WLAN plays important role in remote patient monitoring, it represents the intermediate component between the WPAN and the backbone of WSN ,In this paper we introduced a proposed switch-case algorithm to improve the performance of the WLAN by decreasing the delay and increasing the throughput for any degradation especially if there is a huge degradation that can be caused by dense patient monitoring, this algorithm has five improved mechanisms include enhanced techniques of 802.11n such as block acknowledgment, Channel bonding, frame aggregation and spatial multiplexing. This algorithm is equipped to both nonjamming and jamming environments.

“…In the sub frame header the values of destination address and sender address should match with the values of receiver address and the transmitter address in the MAC header. The maximum frame length allowed in A-MSDU scheme is 3kb or 7kb [2]. Every sub frame consists of a header these headers is followed by packets that arrived from logical link control and 0 -3 bytes of padding [10].…”

The outer scheduler separates delay sensitive applications from the incoming burst of multi-part data and also decides whether to apply Aggregated -MAC Service Data Unit (A-MSDU) aggregation technique or to send the data without any aggregation. The inner scheduler schedules the remaining (delay-insensitive, background and best-effort) packets using Aggregated-MAC Protocol Data unit (A-MPDU) aggregation technique.
