Coordinating Interfering Transmissions in Cooperative Wireless LANs

Deploying and configuring wireless mesh network in coexistence of highly interfering wireless LANs

In wireless mesh network, environmental conditions and location of “nodes” on the network are largely unpredictable and in a constant state of change. Heterogeneous signal propagation patterns in addition to interference from existing infrastructure pose significant challenges for a wireless mesh network design. In this paper, we explore, by experiments, link performance results produced at Qat...

Cooperative Transmissions for Random Access Wireless Networks with MPR Channels

A random access protocol for wireless networks was recently proposed in [16], that achieves high throughput by exploiting cooperative diversity of network nodes. According to that scheme, when a collision occurs, the network nodes bounce off the signal that they heard during the collision slot. The base station, by processing the collided packets and the relay transmissions can recover the coll...

A New Cooperative MAC Protocol for Wireless LANs

This paper introduces a new cooperative MAC-protocol for wireless LANs. This scheme is totally compatible with the legacy systems and leverages the multi-rate capability of IEEE systems. The proposed protocol is evaluated via theoretical analysis and the result shows a throughput improvement using the same physical layer as in IEEE802.11b.

Wireless LANs

Wireless LANs based on the IEEE 802.11 standard have achieved wide customer acceptance in the enterprise environment. They are expected to continue to expand in popularity and become ubiquitous communication systems even in private and public places. This paper discusses the basics of the wireless LAN physical layer, focusing on radio tranceiver specifications and design options.
