Existing multi-channel protocols have been demonstrated to significantly increase
aggregate throughput compared to single-channel protocols. However, we show that …

Multi-hop wireless networks employing random access protocols have been shown to incur
large discrepancies in the throughputs achieved by the flows sharing the network. Indeed …

IEEE 802.11 MAC protocol has been the standard for wireless LANs and is also
implemented in many simulation software for mobile ad hoc networks. However, IEEE …

We demonstrate that CSMA/CA networks, including IEEE 802.11 networks, exhibit severe
fairness problem in many scenarios, where some hosts obtain most of the channel's …

Collisions are a main cause of throughput degradation in wireless local area networks. The
current contention mechanism used in the IEEE 802.11 networks is called carrier sense …

The distributed coordination function (DCF) mode of the IEEE 802.11 MAC standard, though
proposed for medium access in wireless local area networks, is seen as the de-facto …

Carrier sense multiple access (CSMA) protocols, such as the IEEE 802.11 protocol, are
widely used in wireless ad hoc networks. In this paper, we consider how the parameters of …

This paper proposes a novel distributed multi-channel medium access control (MAC)
protocol using fast and slow hopping sequences with dual radio interfaces. Specifically, one …

This paper proposes a medium access control (MAC) protocol for ad hoc wireless networks
that utilizes multiple channels dynamically to improve performance. The IEEE 802.11 …

We consider the problem of efficientMAC design for long-distance WiFi-based mesh
networks. In such networks it is common to find long propagation delays, the use of …
