Abstract
The rapid change of topology is one of the most important factors affecting the performance of the routing protocols of flying ad hoc networks (FANETs). A routing scheme suitable for highly dynamic mobile ad hoc networks is proposed for the rapid change of topology in complex scenarios. In the scheme moving nodes sense changes of the surrounding network topology periodically, and the current mobile scenario is confirmed according to the perceived result. Furthermore, a suitable routing protocol is selected for maintaining network performances at a high level. The concerned performance metrics are packet delivery ratio, network throughput, average end-to-end delay and average jitter. The experiments combine the random waypoint model, the reference point group mobility model and the pursue model to a chain scenario, and simulate the large changes of the network topology. Results show that an appropriate routing scheme can adapt to rapid changes in network topology and effectively improve network performance.

Mobility is one of the most prominent features of mobile ad hoc networks (MANETs) and one Mobility is one of the most prominent features of mobile ad hoc networks (MANETs) and one of of the important factors affecting network performance
In response to the above objectives, this paper proposes a solution for choosing routing protocols in highly dynamic flying ad hoc networks (FANETs), namely topology change aware routing protocols choosing scheme (TARCS)
From 0 s to 200 s nodes move with the RWP model, they move with the RPGM (g = 5) model from 200 s to 400 s, and nodes move with the
Summary
Mobility is one of the most prominent features of mobile ad hoc networks (MANETs) and one Mobility is one of the most prominent features of mobile ad hoc networks (MANETs) and one of of the important factors affecting network performance. Being a typical subset of MANETs, the the important factors affecting network performance. Being a typical subset of MANETs, the node node mobility in flying ad hoc networks (FANETs) [1,2,3] is stronger and severely impacts the mobility in flying ad hoc networks (FANETs) [1,2,3] is stronger and severely impacts the network network performance (Figure 1). In FANETs, www.mdpi.com/journal/electronics high-speed moving nodes usually need to complete multiple tasks, such as search/exploration, Electronics 2018, 7, x; doi: FOR PEER REVIEW. The node mobility mode (such as node motion speed, direction, distance, etc.) changes which will cause the network topology to change rapidly and seriously affect the network performance
