Performance improvement of IEEE 802.11n WLANs via frame aggregation in NS-3

IEEE 802.11 based Wireless Local Area Networks (WLANs) are widely used because of its flexibility. IEEE 802.11n is the latest inclusion in IEEE 802.11 standard. High throughput can be gained by enhancing the performance medium access control (MAC) layer. In that case MAC layer Frame Aggregation Mechanism can be used. Two types of frame aggregation are introduced by this standard namely MAC Service Data Unit (MSDU) aggregation and MAC Proto-col Data Unit (MPDU) aggregation. In this paper we have implemented an aggregation scheme by combining these two types of mechanism an analyzed its performance by using NS-3 in multi-client mode. The simulation result outperformed in case of throughput.
