To tackle these challenges, in this paper, we propose adopting the current mesh standard, namely IEEE 802.11 s, in its routing capabilities to provide improved performance. Specifically, we propose two new link quality routing metrics called SrFTime and CRP as an alternative to the IEEE 802.11 s default Airtime routing metric to meet network throughput requirements for FANET applications. Basically, SrFTime improves network performance of stationary FANETs, while CRP is designed to fit the transient link characteristics of mobile drones and enable more efficient routes from drones to their destinations. To be able to test these metrics, we also introduce a group mobility model adaptation for FANETs needs.
