A throughput analysis of the Persistent Relay Carrier Sensing Multiple Access (PRCSMA) protocol is presented in this paper. The protocol has been designed to execute a cooperative ARQ (C-ARQ) scheme in wireless networks. The model herein presented takes into account the contention time among the relays. This time consists in wasted time due to both backoff deferral periods and collisions occurred...
The distributed queuing MAC protocol for cooperative networks (DQCOOP) is presented in this paper as an innovative MAC protocol designed to coordinate the relay retransmissions in a cooperative automatic retransmission request (C-ARQ) scheme for wireless networks. The distributed cooperative ARQ scheme when the DQCOOP is applied at layer two is compared to an ideal non-cooperative ARQ scheme. Computer...
