Abstract: Wireless local area network is emerging field in research and science. It is all about the transmission of data through various networks. The common categories of data transmission are email, twitter and web browsers. These days, the WLAN are being capable to support various time sensitive services like voice and videos. Most of the applications of WLAN are seen in hospitals, at airports and in huge commercial areas. Further, WLAN is not just support to Ethernet but also applicable for providing better quality of services (QoS). The local network is more flexible, scalable and mobility of nodes does not create traffic on network. There is use of some routing protocols that improves the working criteria of WLAN. The routing protocols are EDCF (Enhanced Distributed Coordination Function), HCF (Hybrid Coordination Function), DCF (Distributed Coordination Function) and PCF (Point Coordination Function). Firstly of all, the study of 802.11 is required before moving on the routing protocols. It is discussing about the shortcomings of QoS of a network and performed two types of operations as DCF and PCF. In this research work, the chief focus is on the EDCA, HDCA and BFOA (Bacterial Foraging Optimization Algorithm) which is inspired from the behavior of enzymes as name Escherichia Coli and utilized with the use of Chemo-taxis. In this work, a new optimized HCCA 802.11E is discovered mainly for the safety and real time systems under the Wireless local area networks. In research work, we will perform the optimized (BFOA) service intervals and TXOP calculations in hard real time scheduling scenario. Then it will evaluate the performance of the system in terms of end delay, throughput and packet losses in hard real times and evaluates the performance with the base approach. The results are generated from proposed work demonstrates that the packet loss and end to end delay declined dramatically while throughput is continuously flourished.
