A Cooperative Automatic Retransmission Request Technique Based on Listening Node Participation Competition

To improve the stability of automatic retransmission requests, a competition control method for requests cooperative-based listening nodes is proposed. Because number source involved in communication reduced, reduces energy consumption. Cooperative consists two main parts work. When node sends signals to surrounding nodes, relay and other receive broadcast signals. The received by both are same. A mechanism based on probability link disruption as an indicator designed. with higher identified that retransmits signal. An experiment performance comparison multiple algorithms organized simulation. results show proposed new strategy has lower values BER metrics. This indicates transmits high signal quality compared dominant methods retransmitting forwarded successfully transmitted no longer effort. In cooperative communication, consumed system reduced. improved algorithm achieves low-power practical innovative communication.
