  • Frame aggregation is one of the efficient methods to improve wireless channel utility of MAC (Media Access Control) and spectral efficiency. Aiming at multi-services, this paper adopts two-level buffer mechanism and polls each queue for aggregation according to aggregation weight factor. The aggregation weight factor of each queue is dynamically adjusted based on the packet overtime urgent factor defined to meet with the delay requirement of each QoS type of service. This paper introduces queue theory into the performance analysis of frame aggregation scheme. A mathematical analysis model is set up. Additionally, the relationship of main performance parameters and system load is quantificationally analyzed. Compared with the performance of the two-level aggregation scheme defined in IEEE 802.11n standard, the proposed scheme indicates the performance of the new frame aggregation scheme is more efficient than the two-level aggregation scheme defined in 802.11n standard.
