Design and Implementation of a Virtual Quality of Service MAC Layer (VQML) for Wireless LANs
نویسندگان
چکیده
Wireless LANs are becoming increasingly popular. While the technology offers wireless connectivity, it offers minimal or no quality of service (QoS) to multimedia applications. We propose a virtual QoS MAC layer (VQML) between MAC and networking layers to provide QoS. The proposed VQML architecture is implemented in a Linux platform and tested in an experimental wireless network test-bed in the Network Research Laboratory of UNSW. This report details the design, implementation, and experimentation of VQML.

متن کاملAchieving proportional delay differentiation in wireless LAN via cross-layer scheduling
Providing service differentiation in wireless networks has attracted much attention in recent research. Existing studies so far have focused on the design of differentiated media access algorithms. Some quality of service (QoS) metrics, such as queueing delay cannot be completely addressed by these approaches. Moreover, without a formalized service differentiation goal that quantifies the outco...
متن کاملMulti-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey
Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

متن کاملPerformance analysis of IEEE 802.11 MAC protocols in wireless LANs
IEEE 802.11 MAC protocol is the de facto standard for wireless LANs, and has also been implemented in many network simulation packages for wireless multi-hop ad hoc networks. However, it is well known that, as the number of active stations increases, the performance of IEEE 802.11 MAC in terms of delay and throughput degrades dramatically, especially when each station’s load approaches to its s...
