Face-routing is one of the reliable recovery schemes when geographic routing fails to transmit data packets. Although studies on face-routing can overcome the failure of the data transmission, they lead to much energy consumption due to frequent data transmissions between adjacent nodes for carrying out the rule of face-routing. To avoid the frequent data transmissions, several face-routing schemes have been recently proposed to transmit data packets to the farthest-neighbor node. However, they happen with many data retransmissions because the farthest-neighbor node has a relatively low transmission success ratio. To solve this problem, we propose a new face-routing scheme that determines the most appropriate neighbor node to balance the trade-off between energy efficiency and transmission reliability with two viewpoints. The first viewpoint focuses on how to increase the distance progress of the data delivery in one-hop range to enhance energy efficiency. After that, the second viewpoint focuses on how to increase the success ratio of the data delivery to enhance the transmission reliability. As a result of the simulation, it was confirmed that the proposed method achieves better performance in terms of energy efficiency than existing face-routing research, and it is better than recent face-routing research in terms of reliability and retransmission.
面路由是地理路由失败时传输数据包的一种可靠恢复方案。虽然面路由研究可以克服数据传输的失败，但由于相邻节点之间为执行面路由规则而频繁地传输数据，因此会导致大量的能量消耗。为了避免频繁的数据传输，最近已经提出了几种面路由方案，以便将数据包传输到最远邻居节点。然而，由于最远邻居节点的传输成功率相对较低，因此会发生许多数据重传。为了解决这个问题，我们提出了一种新的面路由方案，该方案从两个角度确定最合适的邻居节点，以平衡能量效率和传输可靠性之间的权衡。第一个角度侧重于如何增加一跳范围内数据传输的距离进度，以提高能量效率。之后，第二个角度侧重于如何提高数据传输的成功率，以提高传输可靠性。通过仿真验证，所提出的方法在能量效率方面优于现有的面路由研究，在可靠性和重传方面优于最近的面路由研究。
