Opportunistic use of client repeaters to improve performance of WLANs
Currently deployed IEEE 802.11 WLANs (Wi-Fi networks) share access point (AP) bandwidth on a per-packet basis. However, the various stations communicating with the AP often have d...

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...
