Frame Aggregation and Concatenation Schemes for IEEE EDCF 802.11e: A First Order MAC and PHY Cross-Layer Model to Estimate the Throughput

We develop a first order analytical medium access control (MAC) and physical (PHY) cross-layer model to estimate the saturation net throughput of IEEE 802.11e wireless local area networks (WLANs) with MAC enhancements schemes. The MAC improvements analyzed consist of minor modifications of the IEEE 802.11e enhanced distributed coordination function (EDCF) MAC protocol in order to support frame aggregation and concatenation.
