Relay Subset Selection in Wireless Networks Using Partial Decode-and-Forward Transmission
This paper considers the problem of selecting a subset of nodes in a two-hop wireless network to act as relays in aiding the communication between the source-destination pair. Opt...

Multi-rate Relaying for Performance Improvement in IEEE 802.11 WLANs
It is well known that the presence of nodes using a low data transmit rate has a disproportionate impact on the performance of an IEEE 802.11 WLAN. ORP is an opportunistic relay pr...

Architecture and algorithms for an IEEE 802.11-based multi-channel wireless mesh network
— Even though multiple non-overlapped channels exist in the 2.4GHz and 5GHz spectrum, most IEEE 802.11-based multi-hop ad hoc networks today use only a single channel. As a resul...
