Fairness Enhancement Scheme for Multimedia Applications in IEEE 802.11e Wireless LANs

Multimedia traffic should be transmitted to a receiver within the delay bound. The traffic is discarded when breaking its delay bound. Then, QoS (Quality of Service) of the traffic and network performance are lowered. The IEEE 802.11e standard defines a TXOP (Transmission Opportunity) parameter. The TXOP is the time interval in which a station can continuously transmit multiple data packets. Al...

TCP fairness issues in IEEE 802.11 wireless LANs

In this paper, we study several TCP fairness issues in wireless local networks, both experimentally and via simulation. We illustrate the unfairness problems caused by the 802.11 MAC protocol, as well as by cross-layer interactions. Two possible solutions, namely SPM-AF queue management and LAS queue management, are proposed in the paper. These two queue management approaches are designed to al...

Robust SuperPoll with Chaining Protocol for IEEE 802.11 Wireless LANs in Support of Multimedia Applications

Design of Wireless Local Area Networks (WLANs) needs to take into consideration the limited bandwidth available in the ISM band along with the noisy characteristics of the wireless environment and hidden terminal effects. In this paper we propose an enhancement for IEEE 802.11 standard that improves the WLAN support for multimedia applications. In the IEEE 802.11 PCF polling based protocol desi...

Association Scheme with Traffic Control for IEEE 802.11 Wireless LANs

In wireless LANs, wireless clients are associated with one of access points (APs) to obtain network connectivity, and the AP performs network traffic relay between the wired infrastructure and wireless clients. If a client with a low transmission rate is associated with an AP, the throughput performance of all the clients that are associated with the AP is significantly degraded because of the ...

A Delayed-ack Scheme for Performance Enhancement of Wireless Lans

The IEEE 802.11 MAC protocol provides a reliable link layer using Stop & Wait ARQ. The cost for high reliability is the overhead due to acknowledgement packets in the direction opposite to the actual data flow. In this paper, the design of a new protocol as an enhancement of IEEE 802.11 is proposed, with the aim of reducing supplementary traffic overhead in order to increase the bandwidth avail...
