Cooperative communication is becoming a promising technology for wireless networks by exploiting two key characteristics of the wireless medium: broadcast nature and spatial diversity. To integrate cooperation into practical systems, efficient protocols are needed across the entire protocol stack. This paper presents a novel cooperative relay-based auto rate medium access control (MAC) protocol (CRBAR)...
The quality of service (QoS) support in wireless local area networks (WLANs) faces a big challenge due to time-correlated fading channel. Conventional automatic repeat reQuest (ARQ) schemes based on time diversity may result in consecutive retransmission failures degrading QoS severely. This paper proposes a novel Differentiated cooperative medium access control (MAC) protocol, called DC-MAC, to enhance...
Cooperative communication is becoming a promising technology for wireless networks by exploiting multipath fading instead of mitigating its impact. To integrate cooperative diversity into practical systems, efficient protocols are needed across the entire protocol stack. This paper presents a Cooperative Relay-Based Auto-Rate MAC protocol (CRBAR) to enhance the multi-rate capability along a long link...
