Improving Quality of Service in the MAC 802.11 Layer
نویسندگان
چکیده
Quality of service in wireless networks cannot be achieved without the support for service differentiation at the medium access layer. IEEE802.11 layer suffers from QoS limitations that are summarized in [1] along with a survey of the current research work to enhance QoS. This paper presents simulation results to show the effectiveness of prevalent techniques of improving the QoS in IEEE802.11. The paper takes a closer look at the Sliding Contention Window (SCW) technique and presents a performance study that augments the work in [5] by considering network utilization and the determinism in QoS achieved.

802.11 wireless networks are a convenient way to provide ‘last-hop’ network connections in many environments. However the distributed nature of their operation poses problems in providing quality of service guarantees, which are vital for providing interactive services such as Voice over IP. In this thesis we will review the operation of 802.11 and it’s extended MAC layer, 802.11e. We will then...
متن کاملThroughput and QoS Optimization in IEEE 802.11 WLAN
In a wireless LAN (WLAN) based on IEEE 802.11, supporting multiple classes of services with QoS constraints in MAC layer is very important. In this paper, we propose a class-based analytical model to support multiple traffic classes. Through investigating the relationship between access control parameters, such as contention window (CW) sizes and inter-frame space (IFS) under QoS constraints, w...

In VANET high speed is the real characteristics which leads to frequent breakdown, interference etc. Therefore Performance of adhoc routing protocols is helpful to improve the Quality of Service (QOS). In this paper we studied various adhoc routing protocols, Reactive, Proactive & Hybrid, taking in to consideration parameters like speed, altitude, mobility etc in real VANET scenario. The AODV a...
