Abstract

Reduce both the number of retransmissions and the transmission time for each packet to get over the unreliability of the wireless medium. Due to the inherent unreliability of the wireless medium, any transmitted packets are subject to failto decode at the receiver. In this paper, we jointly consider both the cooperative retransmission and the transmission rate control in order to reduce both the number of retransmissions and the transmission time for each packet. We first propose an optimal retransmission scheduling scheme with the optimal transmission rate control. In addition, we propose an advanced scheme by taking the energy constraint into our consideration. By performing an extensive set of evaluations,we validate the proposed schemes.o decode at the receiver.
