Bit Error Correction Without Redundant Data: A mac Layer Technique for 802.11 Networks
In wireless network monitoring, received packets such as MAC frames may contain bit errors. Such errors either makes the monitoring data less accurate, or forces the monitoring software to drop errored frames to avoid such inaccuracy. This paper presents a MAC layer based measurement technique for monitoring 802.11 networks. It...

MRMC: A Multi-Rate Multi-Channel mac Protocol for Multi-Radio Wireless LANs
Dynamic transmission rate selection is widely used in IEEE 802.11b Wireless LANs WLANs to combat adverse wireless channel conditions. However, overall system throughput suffers when stations with different transmission rates share the same physical channel. This paper describes and evaluates a multi-rate multi-channel Medium Access Control MAC protocol to solve...

Experimental Evaluation of 802.11e EDCA For Enhanced Voice Over WLAN Performance
The 802.11e MAC protocol extends the 802.11 CSMA/CA contention mechanism by allowing the adjustment of MAC parameters that were previously fixed. While the 802.11e protocol has been extensively studied, the work discussed in this paper is almost entirely confined to analytical and simulation studies. This paper demonstrates a technique for...

mac Layer Multicast in Wireless Multihop Networks
Many applications in wireless ad-hoc networks require multicast communication. In order to provide efficient multicast, various multicast routing protocols have been designed in recent years to facilitate formation of routes between multicast senders and receivers. There has also been some work to develop a suitable MAC protocol to improve efficiency...

Split-Channel Pipelined Packet Scheduling for Wireless Networks
To reduce Medium Access Control MAC overhead and improve channel utilization, there has been extensive research on dynamically adjusting the channel access behavior of a contending station based on channel feedback information. This paper explores an alternative approach, named pipelined packet scheduling, to reduce the MAC overhead. MAC overheads can...

The Case for Heterogeneous Wireless macs
This paper analyzes the interference mitigation strategies in existing 802.11 WLANs and shows that incomplete and inconsistent channel status assessment due to intra- /inter-BSS interferences leads to the hidden/exposed terminal problem. The paper then proposes a novel approach based on a class of heterogeneous MAC protocols that are not only...

Enterasys LAN Switching: Deploying IP Multicast Switching
With the advent of more IP multicast based applications coupled with the deployment of larger switched LANs, the possibility of non-unique MAC address mappings in an IP multicast environment is greatly increased. The presence of non-unique MAC multicast addresses prevents IP multicast capable switches from building independent MAC layer multicast...
