Demands for QoS challenging wireless multimedia services are continuously increasing for both professional and entertainment needs. Efficient wireless technologies, able to offer the corresponding throughput and QoS are required. The IEEE 802.11n is the latest wireless standard. It introduces many improvements at both Physical and MAC layers. However, and despite the increase of the physical data rate, the large overhead associated with channel access and packet transmission schemes reduces its overall efficiency, mainly at the MAC layer. In this paper, we propose QoS-HAN: a new scheme for the 802.11n aggregation process. QoS-HAN is mainly designed to meet the requirements of multimedia services over Home Automated Networks (HAN). It takes into consideration the size of the packet during aggregation. The proposed scheme is evaluated and examined for different types of traffic. Simulation results demonstrate the efficiency of the proposed scheme in terms of throughput, delay and PDR.
