ABSTRACT
The improvement on the ETE reliability is not the only benefit that we can get from cooperative routing. From another aspect, the total power consumption can also be reduced by using cooperation. Various cooperative routing algorithms have been developed to further reduce the total transmission power of cooperative transmission [22, 23, 24, 25, 26]. However, most existing cooperative routing algorithms are implemented by identifying a shortest path first, and thus the performance gains of cooperative communication cannot be fully exploited. Motivated by the QoS-driven routing algorithm in Section 2.4 and the optimal power allocation of DAF cooperative link in Section 7.1.1, we propose a power-efficient cooperative routing algorithm as follows.
