Spectral efficient transmit diversity techniques without cyclic prefix for fading relay channels
Abstract--This paper proposes spectral efficient relayassisted transmit diversity techniques, i.e., space-time and space-frequency block codes (STBC/SFBC), for single carrier frequ...

Design of a Channel Characteristics-Aware Routing Protocol
Abstract—Radio channel quality of real-world wireless networks tends to exhibit both short-term and long-term temporal variations that are in general difficult to model. To maxi...

Coupled 802.11 Flows in Urban Channels: Model and Experimental Evaluation
Abstract—Contending flows in multi-hop 802.11 wireless networks compete with two fundamental asymmetries: (i) channel asymmetry, in which one flow has a stronger signal, potent...
