Abstract

Enhanced distributed channel access (EDCA) protocol of IEEE 802.11e WLAN standard supports access category (AC) wise quality of service (QoS) differentiation. But the EDCA does not fulfill the very stringent QoS requirements of hard real-time applications. Keeping this in mind, in this research article, we have enhanced the QoS feature of EDCA by adding transmission opportunity (TXOP) based frame-concatenation with block-acknowledgement scheme. Together with these enhancements, we have proposed an analytical model for the performance analysis of EDCA using three-dimensional Markov chain. The contemporary models of EDCA support only a small subset of features. Our analytical model covers all salient features of EDCA. Also, the enhanced frame-concatenation with block-acknowledgement feature is included. The computed throughput and delay characteristics for both EDCA and EDCA with enhanced frame-concatenation with block-acknowledgement scheme are thoroughly studied and compared. Analytical and simulation results match pretty well and validate our model.
