Title: Improving Performance of Voice over IEEE 802.11e   

Author Name: Chenna Reddy P   

Synopsis:   

Quality of service is how well the network satisfies the user requirements. IEEE 802.11e is the quality of service extension of wireless LAN standard IEEE 802.11. IEEE 802.11e achieves quality of service by service differentiation using the parameters Arbitration interframe space and contention window. They are set to different initial values for different flows to achieve service differentiation. But the procedure used to change contention window is same for all the flows. In this paper the contention window is adjusted differently for different flows to improve the performance of voice. Network simulator, NS2, is used for simulation.
